Description

Ha 200 gain 50 offset

With this image, I had just switched over to using an OAG and in doing so I got the spacing wrong by about 4mm too much. With the extra spacing, the stars suffered somewhat. Especially at the edges of the frames which I cropped out. Overall I wished I would have made the switch to an OAG along time ago! In the end, it's a much simpler setup and less to go wrong once everything is configured.
