NGC 891 is an edge-on barred spiral galaxy in the constellation Andromeda, located about 30 million light years from Earth.
This was imaged using a combination of cameras and telescopes. I imaged the luminance with the QSI 683 wsg-8 and the color data was imaged with a modified Canon T1i in 2011.
Combination of 240 sec. and 360 sec. exposure stacked in DeepSkyStacker for a total of 5 hours and 23 minutes in the RGB channel
