On this page I am attempting a careful electronic sketch simulation
of what I saw while on the Antiparos island, with my equipment:
Chinon BCF 11x80 binoculars, Apogee multicoated 20x100 binoculars and my crappy Tasco 60mm/700mm at 35x.
The Tasco has been fortified with a good zoom 22-7.4mm eyepiece from
Apogee, a 45 degree diagonal (so all images are erect) and a shorty 2x
Barlow, which I rarely used.
I am more concerned with giving the sketches a realistic appearance, i.e. for them to represent well what an observer sees through the above equipment.
All the sketches were
digitally processed using Photoshop from observations made on average
6.7+ skies. Contrast and brightness have
been changed sometimes globally, sometimes locally and extended star
images have been antialiased, where applicable,
although I am paying more attention to extended objects and not star
images, aiming at a realistic simulation.
Calculations for the digital processing assume correct fields of
vision of all three instruments and changes in brightness according to
what I saw, in most cases. Occasionally, field edges have been
cropped, to save space and time. The processing has been done on a
Presario 2100 laptop with its screen at full brightness.
For the full observing reports, consult the two articles on 11x80 and 20x100.
