I'm using one of these as a big fat finder on 'Odessius'. Its optics are good enough as a finder. You see it on the 'top' pole of the scope. I added a redspot finder to it too. The second pic is of it while mounted on the old solid tube Odyssey II before the rebuild. I also made the cross-hairs eyepiece from an old Kellner 25mm eyepiece, which is as long a focal length as practical for this focal ratio. It is light, punchy and gives me the same image orientation as the main scope.
If you are considering using this scope as a guide scope, I don't think it is the best option. Anything shorter than a 25mm eyepiece and the short comings of the mirror become much too evident. It is a shame as this scope would have a really good following if the mirror was a half decent parabolic. It really would be in a league of its own. Instead, it disappoints.
