ASTRO: M90

Look at all of the faint fuzzies in the surrounding field! Scott I've got really dark skies here when the sky glow isn't up and running. Come summer it can really be a problem then again in late fall it gets bright, often with aurora to make matters worse. So usually there are a few dozen Unidentified Faint Objects (UFOs) in the background of most of my shots. I even had one in a shot of a small piece of the Veil! That really surprised me. Though in this shot half the stars are fuzzy. Seeing wasn't the best, rarely is, but think most of those too are tiny galaxies. Galaxy season is over. I lost this month to clouds, with little rain unfortunately. I have a few on the hard drive that I didn't like the looks of when taking them but that's all I have left to process. A couple are coming out better than I expected. One of those is M98 which I'm posting now. Stay tuned for a few others. Today I have to tend to some downed trees from the last rainless storm before the next one hits. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct.

Beautiful image Rick.

M90 reminds me a lot of M64, the Black Eye Galaxy. It has a similar set of dust and star clouds in relation to the nucleus and the rest of the arms are not well defined at all. The star clouds in the dust lane show lots of reddening, same as in M64 as well. Just the dust isn't quite as thick and extends further around the galaxy. 14" LX200R @ F/10, L=9x5' binned 2x2, RGB=3x5' binned 3x3, STL-11000XM, Paramount ME Rick -- Correct domain name is arvig and it is net not com.

Thanks. M90 is has interesting detail on a scale I can resolve with my
normal 3.5" seeing. Others have detail that's below my seeing level unless I get a good night. Going on my third week of clouds and little rain with no imaging, I'm down to processing those that didn't resolve well. Though one or two may surprise me.
