LOL! Thanks Daniel
Don't let the presentation fool you though. It wa very simple to make - I was lucky that I had parts that fit my needs just lying on my shelf from old scopes and projects. The focuser is a William Optics SCT 10:1 crayford, screwed on to Meade 2" visual back ex my 12" LX200GPS. I put an electric focuser on the LX so this part suddenly became free. It's been interference-fit massaged into the rear of a section of 100mm-odd poly pipe and glued in place. The front is the cell as it comes from SurplusShed, but with a stainless steel cap off one of our thermos flask cups.
The hardest part (and this is still very simple) is getting the length of the tube right. You just lay stuff in a line on a bench, look along it, and get an idea of where the whole setup focuses, (before and after the focal point with an average 26mm EP) and then measure the distance between the cell and the focuser. Cut your tube to that length and viola. Screw on a finder bracket and dovetail and you're away!
