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?
