Object name: ARP330
Designation(s): ARP330, SHK16,
I'd been hoping for a really good night to image this group. Finally, we had one and the northern lights turned on so bright you could read a newspaper. I might as well have been imaging from downtown Chicago. I ended up throwing out a third of the luminosity images and half of the red, green and blue images keeping the best two. Still, I had super nasty gradients. Normally my background would be about 250 counts out of 65,000 but this image was 14,000 at the upper left, falling to 8,000 near the lower right but then a huge ray or something popped up taking the very lower right corner to 39,000! Thank goodness for GradientXTerminator. It took several applications using various techniques but I ended up with a usable but not great image. My biggest worry is color balance after removing so many gradients. But I think I'm rather close to being correct even though most of the galaxies seem overly reddened.
