Description

2 x 600s Luminance and 3 x 600s each for RGB.

ARP117 is the biggest galaxy on the left, ARP79 is the unlabelled blue compact spiral in the middle. The bright spike on the left is courtesy of Arcturus at 2 degrees distance... Lots and lots of faint background images in this field!

In the final version I added a lot more RGB and an hour more Luminance.

21 x 600s Luminance, 11 x 600s G, 9 x 600s each R & B.

The spike from Arcturus turned red now!
