I mentioned back in Post #023 that in 1978, I purchased from Star Instruments a 4.5" f10 Ritchey - Chretien mirror set. If I remember correctly, these sets were offered as prototypes. They were testing production for a possible future line of optics. A couple of times years back, I asked on line if anyone else had purchased one of these mirror sets and if they had constructed a scope using them. I have never received a reply over the years. I'm still interested to hear from anyone about their experiences.
I am including a few pictures of the scope I constructed in the hope that it will bring back some memories. I know, that was 30 years ago!
