Description

A long time ago I owned an Atik One 6.0 mono camera, but ended up selling it because I had very few clear nights, so it was difficult and frustrating to be able to image anything... and I needed the funds. This is one of the few data sets I have from that time using the camera, and despite some strange artefacts in the background and collimation issues with the 8" reflector, I thought I would re-process this, now that I have a better monitor, so I could see what I could get. All in all I am happy with this. I think I had about 10 subs of M51 in each of the filters, each at 4 minutes exposure time. And so, 2 hours and 40 minutes is thus the approximate integration time.
