Hello! I've been struggling with getting my focus down with my 8 inch LX200 classic and SBIG ST-402. Laast night, I switched froma Meade DC focuser to a Robofucs. The focus is much better during the evening's run.
Whe I checked my B and V images of R CEN, there is a distinct haziness about 1/2 arcminute south of R CEN. My previous images over the last two months were of variable quality, so I'm not sure what I'm seeing, but I can make myself imagine a haziness close to R CEN in those images, as well.
Could internal reflections create this? Could someone take a look and see what they think?
Thank you and best regards.
