NGC5033

My first image from the SX Trius 814 was of the NGC5033, a very massive (2 trillion solar mass) galaxy which is also known as the octopus galaxy. Additional galaxies are also shown in the image, the most notable being the one on the bottom left (NGC5005) which is relatively close neighbouring galaxy.  The image was acquired with ACP Expert and processed with CCDstack2+ and Photoshop CC.

LIGHTS: L:14; R:12:G:9:B11 at 600s; BIAS: 100; DARKS: 30; LIGHTS:40 all at -20C.  

(As an aside: this was my first image to use a new method of dark frame subtraction - take a long DARK (1800s) and let CCDstack calculate the dark frame subtraction with the goal of minimizing the signal to noise ratio).
