Sh2-240 supernova remnant (mosaic)
I've been meaning to capture the other half of this thing for over a year now. It's just an enormous target, more than filling the FOV of my widest scope/camera combination.
It's also a very faint target ... please forgive the noisiness, I cranked up the curves to better show the faint nebulosity.
Thanks for looking!
