Outstanding! Simply Outstanding! Mark Shelton headed down the Refractor Path. I cannot wait to see where this ends up in two or three years. :)

Chuck, I purchased the F10 60" focal length, 6" diameter. I am thinking long term of making a Wood Body for the scope. I have the capabilities of turning a 5 foot tube or so on the wood lathe. Just starting to think this project through. I will be making this most likely next summer or the summer after that. I think a wood turned telescope body would be fun and challenging to do.

Hi, Thanks for the information.
I ordered the 6" mirror cell and Objectives. I am assuming I only need 1 mirror cell?
Actually it's a lens cell, and both objective elements fit into it. You need one cell for each objective (each objective being one crown and one flint element). These are not push-pull cells, so getting your tubing precisely squared-on is almost a must- not a big deal in practice. It makes collimation much easier. Old-school, tried and true stuff.
If you bought more than one objective, you'll need a cell for each. Which f/ratio(s) did you go for?
