Description

I found this one while revisiting my old data. It is from a series of trying different settings when i used a uncooled ASI178MC. I spent evenings imaging M 57 - it is an easy target and i used it as some kind of reference-object. Surprisingly this is the only image of Messier 57 with the native focal length of the RC (without the reducer). It is not the best image i ever took of the ring nebula, but the image has earned its upload because of being the only one at 1624mm focal length :-)
