Imaged with the Maksutov 180mm F/15, at full focal lenght of 2700mm !
Imaging over two nights in April, 314 frames were colelcted, 101 frames 120″ and 212 frames 60″ at Gain 100.
This gain value did not raise up to expectations, I could see more noise in the end result easily. Compared to what I’m used to at Gain 0 with this camera.
This is a pretty faint nebula, an 8800 year-old planetary nebula, situated a little northeast of Procyon.
It’s surface brightness is very low. During the imaging session, the nebula was almost invisible on the monitor. I’m really surprised it came out so good. Obviously this is not a narrowband image, it’s created using a One Shot Color camera.
