Ladies and gents,
there is yet another DIY on the A.S.I.G.N. Observatory website. It's a rail and ring mount for a piggyback telescope, on top of your main scope.
In this case I have selected an APO ED 80, with a 90mm diameter OTA, but the dimensions can be changed to suit any size scope.
The job is about 3/4 of the way through and I should have it finished by the end of the week.
