Description

This was some data I took in January with the SkyGuider Pro and my camera lens. I went back and reprocessed some old data with Affinity Photo.

My calibration frames had a little bit of issues (light leak), and this was before I knew as much about watching the histogram on my camera instead of relying on information on the camera such as read noise, etc. I also had some settings on the camera that I have since changed or disabled that don't work well for astrophotography.
