NGC4490&4485Cocoongalaxy BG 150pEQ3 29_03_2019STa
The Cocoon galaxy.
Actually two galaxies, those being, NGC4490 & NGC4485
They have spent millions of years interacting with each other, but are now moving apart.
My equipment for the image was a Skywatcher 150p reflector on a EQ3-2 mount fitted with dual axis motor drives. So it was tracking, but not guiding.
Canon 1100D, stock version. An intervalometer for the camera control.
Best 40% of 260 light frames, each of 30 seconds at an ISO rating of 1600.
40 frames each of Darks, flats, dark flats & bias.
Stacking software was DeepSkyStacker
Processing software was StarTools.
