An 11x80 Chinon, 20x100 Apogee and Tasco 60mm/700mm Observing Report From Antiparos
Version 1.2.2 of 22/4/2010-4:15 p.m.
After the author with his Equipment came back from the Greek island of Antiparos which lies in the middle of the Aegean[1][2]. After 1-2 hours of night adaptation:
Date: Friday 6 August, 2004. Skies: 5+
Preparations: On Friday, the author did a bit of surgery on the Tasco's
objective hoping to improve on the image's quality a bit, but it turned
out to be unsuccessful. He spaced out the two elements using paper clips
at 120 degree angles but the image showed several distortions and
annoying ghosts at the places where the clips were placed and
tried a star test which failed miserably, as it showed double stars,
similar to that when a close binary barely resolves. He then
removed the clips returning the objective to its original state and a
new star test showed again traces of misalignment.
Turns out the objective was slightly pinched. The author rotated it and loosened
the retainer a bit and after a bit of tinkering it returned to its
initial semi-acceptable state. The 45 degree Apogee diagonal was of
course a disaster, as it is meant for terrestrial viewing and the author didn't
know this when he ordered it. Stars with this diagonal, simply fail to
show decent diffraction rings. The two elements of the diagonal somehow
distort the image exactly in the middle, showing intense flares exactly
aligned with the diagonal's horizontal axis cut. So much for star image
quality.
First day on Friday, the author aligned the 20x100/Tasco pair using a distant
sailboat and carried the 25 lbs tripod out at around 22:00. He checked
out a couple of objects before the moon came out. First, his favorite
obligatory ones, so he could quickly compare the two binocular pairs.
M22: One can't even begin to describe
how this monster looks with the
20x100 pair. It's so huge and of the same order of brightness as the core of
M31. It might even be brighter. Uniform spherical glow, with several
cutoff areas around the left and bottom sides, but it did not resolve.
The author kept returning to it again and again, simply because it is so
mesmerizing and scary. Looking at it with the Tasco on the side at 35x, only a
fraction of its glory was visible but it did not resolve
with the Tasco either. On Saturday it was even brighter than on Friday.
A totally fascinating object. For this author, it is much more impressive than M13. This object
still gives the author the creeps. He cannot even start to imagine what lurks in
there.
M8: (Lagoon). From dark skies, the author was able to clearly and
with direct vision make out the shape of the entire nebula. The 20x100 pair
shows it as a black and white reproduction of the more famous H-alpha
photos, that show so many details. The dark lane that separates M8 from
NGC 6530 was easily visible and the boundaries of the entire object
were distinct, sharp and visible with direct vision. The sketch from "Turn
Left at Orion" is almost a joke compared to what the author could see with the
binoculars. He'd say the sketch probably resembles more of what the
Tasco telescope is able to show on M8. With the Tasco at 35x, all the nebulae stars
except the 3-4 big ones require averted vision. With the 20x100 pair,
around 2 dozen are visible directly. The nebulosity is
extensive and covers around 10% of the Apogee pair's field.
Moving a bit north, the author tried to locate M20 (Trifid nebula), which gave him lots
of trouble two years ago with the 11x80 pair. With the later pair, two years
ago, he had trouble locating it, but he suspects that this trouble came
predominantly because he had never seen it before and because it was
relatively low on the horizon. On Saturday the author waited until it reached
all the way above the sea to its highest location (which was roughly
30-40 degrees above the horizon) and he
moved about a field north of the Lagoon nebula with the 20x100 pair and there it was:
Obviously discernible, with direct vision and quite bright. Two
distinct nebulous patches, of almost equal intensity. The southern
(pink) part showed traces of dark lanes with averted vision and the
central star was easily visible. The northern (blue) part (which the author hears
is independent of the Trifid part) was almost as thick as the Trifid. CD22
and CD23 were clearly visible and almost of the same magnitude. Using the
aligned Tasco telescope on it at 35x, the author was baffled even more, as it was visible
on the telescope as well! The Tasco showed the two stars (CD22/23) well, but the
nebulosity around both required some averted vision. It's definitely
within the capabilities of a 60mm lens if one knows where to look. Then
the author aimed the 11x80 pair at it and his suspicions were vindicated: It is
visible alright, but the blue part hinges on the verge of visibility of
the later pair, whereas with the 20x100 pair it is visible using direct
vision. That's why the author had trouble seeing it two years ago. On the same
field of view M21 is also visible, and very bright with the 20x100 pair.
Date: Saturday 7 August. Skies: 5.4+
Saturday the author fired up Cartes du Ciel on the porch and he looked
around M8 to see if he could locate any of the closer objects. He spotted M28
relatively easily with the Apogee pair, but although clearly visible,
it was much less impressive than M22. The Apogee pair did not resolve this
either. The author also spotted NGC6544 easily. This one was not an easy target
for the 11x80 pair. The 20x100 pair showed a distinct nebulosity there, albeit
small. The 11x80 pair showed something there, but the author couldn't tell what he was
seeing.
Next the author moved to M17 (Swan nebula) and his jaw almost dropped on the porch. The
famous "check-mark" was extremely bright and the rest of the nebula was also
visible with direct vision. Several distinct absorption regions were
visible, with the one defining the back of the swan's "neck" being the
most prominent. The sketch on "Turn Left at Orion" is only a joke
compared to what the Apogee pair shows. Around two dozen stars were
visible interspersed in the nebula. Of course, at the time of
observation, the entire Sagittarius region was as high as
it could be above the horizon.
Next the author momentarily used Antares to re-align the Tasco/Apogee pair and
looked at M4. Beautiful, just beautiful. Although not as bright as M22,
this one definitely shows several (he'd say around a dozen) stars
resolved, with the 20x100 pair. There are continuous sparkling stars
blinking on and off everywhere inside the cluster! Both near the center
and near the edges. The Tasco telescope played dumb on it. Although easily
visible, no traces of resolving individual stars inside it. The resolving
limit of M4 appears to be somewhere between 80mm and 100mm. With the
11x80 pair there's only a vague hint of resolving. The author couldn't tell for sure,
but he did detect what seemed to be momentary starlike bursts inside the
cluster with the later pair.
Next the author moved on the back side of the house and located M31 which was
just rising against the northern mountain of Antiparos. Needless to say
the Andromeda galaxy is probably one of the best sights with giant
binoculars. The Tasco simply doesn't do this galaxy justice. Although
two years ago the author was able to see traces of the main dark lane with the
Tasco telescope, on Friday he could not detect any such thing, even with the new
Apogee eye-piece at 35x. The author pointed both the 11x80 and the 20x100 pairs against
it as he was determined to nail the two companions M32 and M110. Two
years ago with the 11x80 the author kept looking and looking until his eyes
popped out, but could not find them. So Saturday he zoomed in with Cartes du Ciel (CDC)
and recorded their locations against M31's main figure. As soon as he
mentally recorded their locations, he immediately spotted them. With the
20x100 pair, M110 shows as a relatively
bright elliptical nebulosity above M31's main body, quite far off, but inside the same field of view when
the author positioned M31 on the bottom of the field. M32 still has a starlike
appearance, but it's obvious that whatever this object is, it's not
just a star. The author would say that M32 is on the very edge of M31, almost inside
M31's haze. Curious about how fast he located them, he checked them with
the 11x80 pair. The Chinon pair shows them as well. M110 is probably a
little faint, but it shows clearly with averted vision. Having the
Apogee/Tasco pair aligned, the author also saw M32 with the Tasco. It clearly
shows a starlike object, nowhere as bright as with the Apogee, but
definitely inside the same field of view that includes the galaxy core,
at 35x. It shows how important having a good astronomy program is. The author would
never have located the companions if it wasn't for CDC. As far as M31
is concerned: The object is simply glorious with the Apogee pair: On Saturday
the author could not see any dark lanes, because the coming moon's haze
obstructed part
of it, as it was close to rising behind the mountain. The core is so
bright that the author's impression is that it becomes distinctly point-like. The
haze from the galaxy edges fills half the field of the Apogee pair.
Seeing this object is almost worth the money paid for the Apogee pair.
Last year the author had trouble with M51 as
well, so he tried this one with the
new pair. The 11x80 pair just barely shows the second nucleus and the author
needed lots of averted vision for the core of the main galaxy. This one
is on the limits of the Chinon pair, but with the Apogee pair he got a
huge bang! Both cores are visible with direct vision, the main core
slightly brighter than that of the companion. The full extent of both
galaxies is clearly visible, and although no details are discernible,
the overall nebulosity is quite large and bright with hints of its
shape. Glimpsing it with the Tasco, only a hint of haze from the main
galaxy is visible, requiring averted vision at 35x. The Tasco does this
(but not the companion), but one would have to be a masochist trying to
locate it with a small scope without a good finder.
Next the author picked M81 and M82 in
Ursa Major. The difference here between
the Chinon and the Apogee pairs is quite noticeable: With the 11x80, M81 is
an
easy target, but M82 (the irregular cigar shaped one) is a challenge,
and the shape is not evident, except on exceptional nights and with
averted vision. Contrast this with the Apogee pair, where not only the shape
of M82 is visible with direct vision, but also around 3-4 stars on, or
around the galaxy itself. It was the author's impression that there were contrast
and luminosity differences within the shape itself, probably towards
the center where there is this unexplained bulge, but it might have
been his imagination. However, the image of M82 is definitely not
uniform in terms of brightness. M81 is superb on both pairs. The
Chinon pair show hints of dark lanes and an elliptical patch, but with the
Apogee the elliptical patch becomes much more pronounced, fading non
uniformly around the spiral edges. On Saturday, the upper and lower
arms were visible with the 20x100 pair. At 20x this one was quite a
impressive sight. The Tasco showed M81 if the author covered all traces of incoming
light from the edges of the eye-piece and M82 was at the Tasco's limits. It
shows something there, but nothing more. Occasionally, with averted
vision the author glimpsed a hint of a stick-like shape, but that was about it.
At around 23:30 for a change the author thought it would be nice to chase a bit
after Uranus, to see what the Tasco could do with it. He first had to
identify the Capricorn and Aquarius constellations which were a first for him, since he
wasn't familiar with either constellation. With his Presario and CDC on
the porch, after about 10 minutes he managed to locate both constellations.
Drawing a line between lambda Aquarii and delta Capricorni, he was able to locate
sigma Aquarii, above which sits Uranus. Both binocular pairs showed the newly
seen (for him) planet easily. The disappointment came when the author tried to
discern a disk with the Tasco. A disaster. Uranus' color can be easily
seen, as blue green, but otherwise no disk. The author upped the magnification
to 60x and then to 90x, but no disk, just a very faint blue blur.
Checking with CDC, he read a 3.6" diameter, too close for comfort for
the junky Tasco. The author would say that on the best nights the Tasco won't
separate much lower than 4.5". To conclude, the author was happy that he saw
Uranus for the first time, but no disk was visible.
Date: Sunday 8 August. Skies: 6.0+
On Sunday the author
tried hunting down M33. He targeted
Andromeda for one quick look and swept south a distance equal to that between Mirach and M31. Bang, there it
was: The Chinons showed a quite obvious oval nebulosity with a tendency
to be brighter towards the center. Clearly visible on a dark sky and
quite large. Only the Apogee pair did this object justice, however. The
shape became evident, there were hints of dark lanes and the core of
the galaxy became more pronounced and visible with direct vision. It
did
resemble an oval S-curled snake, with hints of some of the spiral arms.
Very large and extended. The core was not visible with the 11x80 pair,
except via averted vision. With the Apogee pair, the object filled roughly
40% of
the binocular field of view and the core was visible with direct vision. The author's
impression is that this was the second largest object (after M31) he's
ever seen with binoculars. The Tasco only showed the core with averted
vision and with great difficulty. The arms were not visible.
Fascinating object. The author would say that this is probably one of the best sights on dark
nights with giant binoculars. He will return again and check it out.
Being in the area, the author also bagged M34. This one was exceedingly pretty,
resembling another little jewel box of the north. With the 11x80 pair
all the individual stars required some peripheral vision. With the
20x100 pair all were visible directly and made a beautiful collection of
jewels.
For a break the author checked Almack with the Tasco and it resolved nicely at
around 10", showing the beautiful contrast between reddish and blue even at
35x. Upping the magnification to 90x, the Tasco performed surprisingly
well and the pair showed perfect Airy disks with a couple of rings
around them. That's the first indication the author had that the Tasco
was somehow ok after the surgery he performed on its objective.
Then M. wanted to see C4/2003 K4 LINEAR, so the author turned the Apogee
towards Arcturus. It formed an upside down isosceles triangle with
Arcrurus and
eta Bootes, and he spotted it easily. With the Chinon pair it looked roughly as
bright as M13. There was a hint of tail, pointing at 11 o'clock, but
this became obvious only once the author turned the Apogee pair on it. It looked
like M13 but the core was much brighter. Then he tried to hunt C/2001 Q4
NEAT in Ursa Major, but he could not locate anything, after looking for
about 10 minutes.
Being in Ursa Major, the author thought he would also bag a couple of Messier objects that he had
never seen, so he looked around CDC and mentally checked M97(Owl nebula), M108
and M109. He didn't even bother with the 11x80 pair, as he knew these were
hard. They were indeed. They were all marginal even on the 20x100 pair.
The easiest was the Owl nebula, which was somehow circular with averted
vision, but both M108 and M109 were on the verge of peripheral vision
even for the giant pair. After holding his breath and performing various
vision tricks, he saw both, but he'd say that these would have to be real
challenges for anything smaller than 100mm. M108 was almost impossible.
The author thinks he saw it, but it might have been his imagination. No wonder they
are not so famous in small scopes.
Then M. wanted to see C4 K4 LINEAR again, so the author returned to
Arcturus. He grabbed the chance to show her M5, which was in the
vicinity. What a nice surprise! This is definitely nice in all three
scopes, the Tasco showing even glimpses of resolving some individuals
at 50x. There's definitely resolution with the Apogee pair and this
cluster competes favorably with M3 and M13.
On Sunday M51 was even brighter, because there was a North breeze in
the morning which seems to have cleared the atmosphere more. This time
the author clearly saw the overall shape of the main component with the 20x100 pair,
which extended all the way to the companion. The two cores were quite
bright.
Date: Monday 9 August. Skies: 6.2+
On Monday the author decided to bag some objects in Ophiuchus. He
familiarized
himself with the constellation as it was the first time he had seen it in
detail and moved to lambda Ophiuchi, thinking of turning left to spot M12 and
M10. These two were absolutely stunning. Both were very bright. M12
resolved in the 20x100 pair and the author saw about a dozen individuals blinking on
and off inside. On the Tasco at 35x, there were still sparks flying on
and off inside the cluster, but it required averted vision for more to
be seen. From all the globular clusters the author has seen, this has got to be the most
easily resolvable. The Chinon pair showed some hints of resolution as well,
but the best view was with the Apogee pair. The author spent half an hour on M12
and it went into his list of favorites. M10 was also quite bright, with
a hint of some darkness in the middle of it, but he just was not
absolutely sure his eyes were not playing tricks. He easily spot M14 as
well and quickly located IC 4665 and Cr 350, using CDC. He then headed
for NGC 6366, which was just above HR 6493. The only scope that showed
this was the Apogee pair. This object was on the limits of visibility
of the 20x100 pair. There was something there, but he couldn't tell that it
was a globular cluster. No way. Too faint. Moving south of zeta Ophiuchi, he located M107
relatively easily as well. This one was small, but definitely within
the light grasp of the Apogee pair. It was barely visible with the
Chinon pair.
Taking a small break, the author fired up Bach's Chaconne on the laptop and
waited some because the neighbor turned on the garage lights. Oh, the
horror of it. Out in the dark for 3 hours and suddenly 3x100 Watt
light-bulbs being turned on. So the author gave Ras Algheti a try with the Tasco,
only to be disappointed by this darn 45 degree diagonal he ordered from
Apogee. Horrible. He could not even focus exactly. This kind of diagonal
is meant for terrestrial viewing, but the author had no idea it would be so
useless for star splitting. He kept getting two images which would not
merge. He moved the objective, thinking it might be pinched, he unscrewed
the retainer some, and the image got fixed some. Then, after 10 minutes
Ras Algheti doubled again. The author didn't know exactly what was the deal here,
but he suspects that the air played tricks on him and somehow the
atmospheric turbulence affected the focus. After an hour of tinkering,
he was able to bring the star into perfect focus and saw the blue
companion at 90x. So much for 45degree diagonals.
The author took a quick look at M13 and examined it carefully with the 20x100
pair. This thing definitely has at least 3 different brightness layers
and is huge. Then he moved onto M92
and his jaw dropped again. Not
as large as M13, but its core is the densest and brightest he's seen.
Even the Tasco showed the bright core with direct vision and it
resembled a very bright hazy star. The core was so bright with either
equipment, that the author's brain was looking for an excuse to resolve it.
Definitely one of the best to look at with small equipment.
The author then tried to split Izar, but no matter what kind of trick he used,
the Tasco couldn't do it. Makes sense, since the Tasco won't even
show Uranus' disk, so he quickly abandoned it.
Then the author momentarily moved back to Sagittarius and took another look at the
Swan nebula. Fantastic. Monday was clearer than Sunday (he'd say around
6.5+) and the entire swan body was visible upside down. By that time the author
laptop's batteries were close to 15%, so he bagged everything and went
inside.
Date: Tuesday 10 August. Skies: 5.5+
On Tuesday we went for a drink downtown and returned around
1:30am. The author was quite buzzed from the drinks, but he still felt like
bagging a couple of objects. M. went to sleep, so he took the
laptop and the equipment out. This time he checked M55 and M75 in
Sagittarius and M72, M73 and M30 in Capricorn. The former were easy
and bright targets, but M72 and M73 were somewhat faint. It took the author a
while to spot, using the little star triangle formed by SD-14 5908,
SD-13 5813 and SD-13 5807 as a guide. Once he located the little
triangle, he saw two tiny nebulous congregations to its right, which he
immediately recognized. He did not view these with the 11x80 pair,
because they were quite faint. On the Tasco they weren't visible, or
perhaps they were so faint that the alcohol in the author's system did not allow
him to see them at 35x.
Being in Capricorn and scanning left with CDC, the author saw NGC 7293 on the
chart in Aquarius, so he thought he'd try that one as well. CDC lists
this as "Helical Nebula", but his mind did not go to "Helix". He thought
it was just another "helical" nebula. Targeting upsilon Aquarii, he saw a
huge patch of light to the right. Wow! It must have been almost twice
as large as the full moon! What a wonderful surprise! It indeed has
quite a low surface brightness, but the shape was obviously visible.
There were at least 7-9 individual stars on it blinking on and off, but
at the time the author was not aware that he was looking at the Helix nebula, so
he did not try to discern details. He'd say that with the 20x100 pair it is
just a tad brighter than M33. It was
so beautiful, the author spent around half
an hour on it, without knowing what it was. The Tasco barely showed
some very dim nebulosity there, but otherwise quite dim for a 60mm
lens. Will return someday and examine it in detail.
By then it was 1:50, so the author moved the equipment to the back of the house
to take a look at the Pleiades. Here, a strange thing happened: The
Pleiades, is of course THE object to view with large binoculars. There
was a thread in sci.astro.amateur, some time ago, asking whether
nebulosity is visible around the group. The strange thing is that the
nebulosity was visible, but with the Tasco, instead of the 20x100 pair! The
Tasco definitely showed haze around the brightest members, but with the
Apogee pair, it wasn't as prominent as with the 60mm scope.
There was some haze in the field of view, but not as pronounced as with
the Tasco at 35x. The author really bugged his eyes trying to see it with the
Apogee, but he is not sure he saw it.
Then the author briefly went over the double Perseus cluster. With the 20x100 pair it
is simply stunning. There is definitely some nebulosity around there,
visible with the giant pair. The two components barely fit inside the
same field. This is also on the author's list of favorites.
Then he also took a close look at Polaris with the Tasco and the new eye-piece. The
main difficulty with Polaris B is that it is magnitude 9.0, and the author is
not even sure the 60mm lens of the Tasco has enough light gathering
power to even show it, particularly against the blaze of the primary.
Two years ago the author easily saw the bluish companion in a neighbor's Meade
ETX 125, at 40x. So the author carefully positioned the Tasco against it and
waited, watching intermittently for about half an hour. The atmosphere
was decent. He was seing a single Airy disk at 70x, surrounded by one
ring, which at times momentarily flared up. He played with the zoom
magnification, going all the way to 92x and at certain moments of
extreme air stillness, he did detect a very faint blink southwest of the
main star, but only for a fraction of a second. He'd say this binary
needs at least 100mm's for comfort. Trying to see the companion with a
60mm scope is like driving a VW beetle at 120km/h.
Although the moon was about to rise, Lyra was now in the West, so the author
thought he'd give M57 a try with the
new binoculars. The sheer weight of
the entire system of the Tasco and the Apogee, prevented him from viewing
at angles greater than about 60 degrees, so he had to wait until Vega
came down a bit. Pointing between Sheliak and Sulafat, bang, it's
exactly in the middle. The Apogee 20x100 pair shows it easily, as a
bright non-stellar object. As with the 11x80 pair, the shape is not
visible, but it definitely looks like a little hazy button, distinctly
different from the surrounding stars. Very bright, but again, 20x is
not enough to give away essential details about its ring shape, nor make
the darker central part visible against the ring itself. Looking
through the Tasco at 35x, there was a hint of ovalness, which became
more pronounced as the author was using peripheral vision. Looking at it as
such, it resembles a smokey oval, but no dark central part. Upping the
magnification to 60x, he could still see the smokey oval shape using
peripheral vision, but otherwise no difference in its central part. Of
course, the author couldn't be asking more from the Tasco, even with the
new zoom eye-piece. The important thing here is that M57 is NOT visible using
direct vision on the Tasco, even at 35x. The 60mm simply does not
collect enough light to allow a direct view. With the Apogee pair, it
is visible directly, but no details are visible, because of the low
magnification.
By then, the crescent moon was out, so the author packed everything and went
inside.
Date: Tuesday 10 August. Skies: 6.7+
Thursday was one of those rare days when the sky was extremely luminous
and clear. The author figured that it would be a great day since the morning
hours, because there was a strong Northern breeze, which lasted all the
way into the afternoon. Three of the neighboring islands to Antiparos
were visible clearly in the horizon at distances of over 35, 40 and 60
km's respectively. Normally these islands are not visible, except on
very cool winter days after a rainfall.
The author's suspicions were vindicated around 22:00p.m. when the Milky Way came out
in Sagittarius. The author doesn't know if you can believe this, but the Milky
Way's reflection was visible against the sea.
The author understood this to be a day to look for some new faint objects and to
check some of the known ones, to make out additional details. He went
over to M81 and M82, only to not
believe his own eyes. The Apogee pair
showed the nucleus of M81 clearly, with direct vision, having a point
like appearance. Averted vision revealed the galaxy's exact shape, with
the pronounced ellipse and with the northern and southern arms readily
visible. M82's curved cigar shape was easily visible and 5 stars were
blinking in its vicinity. The author called M. out and showed her M81 and
she remarked that this was the brightest she'd seen this galaxy during
our stay here.
C4 K4 LINEAR was extremely bright. Probably as bright as M13. M.
saw it and remarked that she could not see a tail Thursday, which she
saw on Tuesday. Truth is, the author could not discern a tail either.
Then the author quickly went over to M51 and
again, and he was pleasantly surprised by the clarity of the night: The cores were visible using
direct vision and the shape of the main component was easily
discernible. Averted vision provided for incredible views of the
overall nebulous shape of both members, with the connection between the
two components visible as a very thin vaporous streamer. The two
components on Thursday were visible with the Tasco as well!
Aiming at Alkaid and Mizar, the author moved north trying to spot M101. Easy,
extended target. He'd say its luminosity was a tad lower than that of
M33. The 20x100 pair immediately
spotted it. With averted vision hints
of the shape were there, but the author did not spend too much time on it. The
Tasco showed the core with averted vision.
Backing up against Ophiuchus, the author rechecked NGC 6366, which was picked up
by the Apogee pair relatively easily, next to HR 6493. CDC lists this
as magnitude 10 and of dimensions 5.8" x 5.8". Would not be picked up if
he didn't know where to look exactly. This
was just too faint for the Tasco. The author reviewed M10 and M12 which under
those skies were fabulous: M12 was resolvable and both cores were very
bright.
Turning over to Sagittarius, the author viewed M8,
M20, M28 and M22 again, as
the night demanded it. Yes, Thursday, M22
partially resolved. The damn bugger resolved with the Apogee pair, so you can expect the object to
resolve only under 6+ skies and greater than 4" lenses. It was just fascinating
and huge. M8 was blindingly bright. The author
counted 17 stars inside it, using direct vision. M. could not believe her eyes. She remarked that
this has got to be the most fascinating object after the Andromeda galaxy and the
Orion nebula.
Checking the Andromeda galaxy under 6.7+ skies, is probably very close
to a mystical experience: The main dark lane was visible, and the
entire object was two entire full binocular fields in width. The dark
lane was visible with the Tasco as well.
Then the author went over and familiarized himself with the Cetus constellation. After he located
most of the constellation stars, he pointed the Tasco against Mira and
upped the magnification to 60x. This was the first time he saw the
little red star. Been hunting it down since age 23. Southeast of delta
Ceti, there was M77 which was an easy target at magnitude 8.9. Inside
the same field of view the author located stars BD-00 410 and BD-00 411, south
of which was NGC 1055 an edge on spiral. At magnitude 10.6, this
required averted vision, but the author saw it. No details, just a very faint
buzz, too faint to be picked up with either the 11x80 pair or the Tasco.
Then the author reworked M92 a bit. The core
was so bright Thursday, that it was
able to withstand 92x on the Tasco. Absolutely stunning and quite
resolvable. On the Tasco the author clearly saw around 4-5 sparks inside the
core at 60x.
By 3:30a.m. Aquila had turned down a bit, so the author hunted down M27. In
passing, he quickly glimpsed M71 in the Sagitta constellation, which was absolutely
obvious and quite bright and finally landed on the Dumbbell nebula after
sweeping the area. M27 was so bright
that the bow-tie shape almost gave
way to an almost circular nebulosity, with extra bright "wings" on
either side. The sketch in "Turn Left at Orion", denotes almost half
the glory of this object in 6.5+ skies and with 20x100 binoculars. The author kept
staring at it for over 20 minutes, using both direct and peripheral
vision trying to make out details. Very impressive. Admittedly one of
the most beautiful objects the author has ever seen.
Went back to M57 after that, and
tried to discern more details. The author doesn't
know why this object fascinates him so much. So he aimed the 20x100 pair
against it: Very bright and distinctly non-stellar. He tried upping the
magnification on the Tasco, to see how much it could take. Yesterday it
could stand up to 92x, easily. However, after around 50x, it required
averted vision. This was the first time the author was able to detect a "smoke
ring", at around 60x, after about 4 years of looking at it. At 92x it
was almost obvious, but only using averted viewing. The "smoke ring" in
this case, is a misnomer for the fact that the central part basically
faded faster than the boundary when one ups the magnification. The author spent
45 minutes on it, trying to convince himself that he was seeing a "ring".
The conclusion is that for non-stellar or extended objects, the Apogee 20x100 pair will
easily pick up anything brighter than magnitude ~10.6. It can pick up even fainter
objects as well, but with averted vision and if one knows where to look
exactly.
At around 3:30, the author's waist could not stand it anymore, so he moved
inside. What an incredible gift to be able to watch the skies from such
a location!
Notes
For comparisons, the author used the book Turn Left at Orion, by Guy Consolmagno, ISBN 0-521-34090-X.
