ASTRO: IC 2574
This is a member of the M81 group. A very faint member. Even at 80
minutes this was a rather noisy image. I needed more color and had been waiting to get it but the skies had other ideas. It is now into my Polaris tree. At its declination I can get it only well east of the meridian when it clears the east side of the tree. At about 3 hours from the meridian it enters the tree and stays there the rest of the year. So I have a short window on this one. Maybe next year. I had figured the bright blue arcs were HII bubbles, apparently not as they were quite weak in red light and strong in blue. Not sure what to make of that. Must be bubbles of hot new stars rather than gas clouds. Next time maybe some H alpha data is in order. 14" LX200R @ f/10, L=8x10' RGB=2x10' binned 3x3, STL-11000XM, Paramount ME Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |
