Hi all,
I know that Messier 31 is a classic image. Probably, together with M42, one of the most imaged deep sky objects. This image has been the result of combining images from three telescopes, a 106 mm and a 150 mm refractors as well as a 24 inch reflector. The goal was to have a high resolution image of M31. You can find it at:
Enjoy,
