Second owner of this scope. Original owner shared an email from Astro-Tech stating that these GSO RC mirrors typically have this rough beveling on the edge. I also have what looks like a very tiny chip on the extreme edge. Is the “rough beveling” or tiny chip of any concern? I’ve seen where you can use a sharpie over a mirror chip to minimize it’s impact. Should this rough spot at the edge be blackened, or are extreme edge defects of no concern for imaging? The clips (see other post) were visible to the secondary, so my concern is the rough edge will be also. Trying to squeeze out the best performance I can from this RC.
