I think the trail off could be a filter/fullframe issue and maybe some tilt in the image train?
Blue is always the most notorious channel for star bloat as it is.

Thanks Nik, yes the 294mc would be much kinder on the OTA that the ASI6200. That said, if there were any serious issues with the OTA you should still see them. Thinking about this, I could try out my Canon 60Da with the scope and see how that goes. The 60Da has a crop sensor so would still give the OTA a good test.
