A prime focus RGB image of the ring nebula M57. I had hoped for a better result but I seemed to have focus issues all night. If I really stretched the luminescence sub-frames I started to pickup details of the nearby faint spiral galaxy IC1296. For more detail the astrobin link is: http://www.astrobin.com/267930
The Ring Nebula (Messier 57) is a planetary nebula in the constellation Lyra approximately 2300 Ly from earh. Planetary nebula are formed when ionized gas is expelled by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf. Taken in narrowband using the California, France, Hawaii Telescope palette (Hα = Red, OIII = Green, SII= Blue) Unfortunately my OIII data was slightly out of focus the the results is not a good as it could be.
