Image above is a "working version" from the HAS site, March 2010. 27x5 min = 2.25 hours exposure from Friday night, 3/12/2010 at the HAS site. Below is a version I did using "drizzle" with the best 29 of 33 frames. Takahashi TOA 130 Telescope (a 5" APO refractor) with flattener, AP 900GTO mount, and QHY8 CCD Camera & normal workflow plus Drizzle.
I think it shows additional detail compared with the older DSLR version below.
This is a very interesting spiral/elliptical galaxy in the constellation Centaurus, which is very low in the southern sky from the US, even from Texas. The dark dust lane through the middle is remarkable. When I started imaging this guy at 4:00 a.m. it was only 15 degrees above the horizon, and only 16 degrees when I finished up.
SEDS moved stuff and this link is broken -> As usual, SEDS has an interesting discussion of this object, and I'll refer you there for more information.
Canon EOS 20Da (unmodified), Takahashi TOA 130 (a 5" APO refractor), Losmandy G-11 mount. 7x4minute - 28 minutes total exposure 1/31/2006 around 4:00 a.m. My current image processing workflow is here.
