Oh, My, Word! I have never seen a Ronchi eyepiece. I have been wanting to test my 10" dob mirror for a long time and this seems so much easier than other methods. Please keep you excellent content comming. P.S. I loved the simple angle mount that holds both motors for the alt-azimuth dobsonian tracking setup. Very simple and clever. Thank you.
