M57 - Ring Nebula
M57, NGC 6720, or the Ring Nebula, is an easily recognizable planetary nebula with an apparent magnitude of 8.8. It is located in the constellation Lyra, where it can easily be found even in smaller telescopes between the stars Sheliak and Sulafat. In small telescopes it appears as a larger out-of-focus star. Only in devices with a larger diameter and with greater magnification can it be recognized that it is a ring. At its center lies an Earth-sized white dwarf that illuminates the nebula and has an apparent magnitude of 14.7.
Also captured in the image is the small spiral galaxy IC 1296 with an apparent magnitude of 14.8, approximately 221 million light-years away. It is a small cloud to the northwest of the M57.
This is one of the first attempts to shoot through the OAG with a long focal length and the SCT C11 telescope". The conditions were quite decent. I originally wanted to shoot M101, but I could not find a suitable point star and refocus, so I chose M57 in the morning as an emergency option. This small object would deserve to be photographed without a reducer and using the 2800 mm focal length, but at three in the morning already to change the set-up the edges of the field are not straight, which corresponds to the reducer used, but this does not matter when photographing such a small object.
