ASTRO: NGC 4395
Seeing was lousy a couple nights ago. It started great but then went
bad quickly as the temperature started to rise rather than fall. During the exposure it went up 5C! Clouds came and went. The guide star ranged from invisible to a 20,000 count during the exposures. Yet, with a lot of work I think I have something usable. This is a very weird galaxy. It appears the size of a galaxy's core is directly proportional to the size of the black hole in it. This galaxy has the smallest known "massive" black hole at its core and the smallest core which is nearly non existent. Making for a very flat galaxy with no bulge at the center. Yet the black hole is still eating something as the nucleus is an active Seyfert 1 class nucleus so is very bright and star-like. The galaxy is rather small, about the same as our large Magellanic Cloud. The arm structure seems very disorganized. Seeing was too lousy to show the HII region's I'd hoped to resolve though a couple are visible. It is only about 14 million light years away. 14" LX200R @ F/10, L=3x10' binned 2x2 (one frame lost to clouds), 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". |
