I just picked up a Daystar Quark Chromosphere to use with my Orion ED80, ST80, and 50mm scope. I have had some good luck so far with the ED80 and capturing prominences but I was trying to use the 50mm to get some full disk shots today and noticed some problems. I think one of my problems might come down to the imaging plane not being exactly perpendicular so I may need a tilt device. I did have some problems with Newton's Rings but once I put an ADC on that I had for planetary, they seemed to disappear. First up, I noticed that one side of the Sun is always brighter than the other and I have noticed this in all three scopes. Here is a screenshot of my live view and is purposely overexposed to exaggerate the difference and make it easier to see what I'm talking about. I have noticed that if I adjust the ADC, this area moves around a little but I can never get it to go away no matter how much I adjust the ADC.
The next is almost like a band that is out of slightly out of focus but more prevalent in the upper left area. I'm adding three different photos with the Sun in different positions in the FOV to show how the band seems to be placed.
