Sh2-240 supernova remnant (mosaic) - a photo on Flickriver

            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!
