M51 Whirlpool Galaxy and M57 Ring Nebula

I took these last night from my light polluted front yard with a streetlight beaming in my face.  I didn't get to use the darks I took since apparently JPEGS are too artifact-y to do pixel by pixel noise replacement.

M51 - Whirlpool Galaxy - made up of about 60 1 min subs at ISO 1600 stacked using Deep Sky Stacker (and then adjusted with Photoshop)



M57 - the Ring Nebula - same setup as above, but about 75 subs (all in one whack using my automatic shutter remote once I figured out how to make it work properly).
