I have only used it once when it produced bad vignetting and an less than sharp image. So I put it in the drawer under my bed and forgot about it.
With a focal length of 500mm (F/7.4) its a lot faster and wider than my old Meade Etx105 so I gave it one last try. I removed the prime lens then split it and cleaned it with alcohol. I made a Batinov Mask from black plastic to improve the focusing and mounted it on my Barn-door Tracker.
I'm quite pleased with the result. Its no triplet but at least I can get some use out of it whilst I'm saving for a better scope.
