Description

After adjusting my old Maksutov 127/1500 mm (my first telescope). I wanted to do some test shots. I chose the Ring Nebula (M57) in the constellation Lyra. Fits well with the long focal length. See the imaging performance of Mak in DeepSky only conditionally suitable. I have selected 19 out of 39 images per score.
