Sharpness 0 Caption The shadow and dot works great. Here's the final alignment position with the sun centered in the eyepiece. It's not perfectly in the cross-hairs, but it's close. Looking closely at the finder shoe, I see it's not quite installed square to the tube, so I could probably adjust that. Or I could just put a black dot with a magic marker at the point where the sun hits. It's not that far off that it matters.
