Is there something I'll see that will indicate that the scope is vignetting?
This isn't a precise, exact answer, but when you look through the focuser without an eyepiece, with your eyeball dead-center, you should be able to see the entire primary mirror without moving your eye around. If the edge of the mirror isn't visible, there is a probable vignetting condition.
Is this something that can be fixed by adjusting the position of the secondary mirror? I noticed that you can adjust the "depth" of the secondary mirror (i.e., closer to or farther away from the main mirror) on this scope. Would that fix the vignetting? Thanks again for your help here. -- Dan
