On this page the author is attempting a careful electronic sketch simulation of what he saw while on the Antiparos island, with his Equipment.
The author is 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 anti-aliased, where applicable. The author is 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 the author 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.
