help! I have no idea what this set of images means
I have a new (used) RC-8 CF. The out of focus star seems good after collimation (see pic).
But...
look at the ugly asymmetrical flat and what is causing these airy disk like effects on the big stars in the m20 image?
Is the scope out of collimation? If so, why can I see fine details like the M20 jet? What else could it be?
