Criterion made a number of unique instruments that they did not advertise about. In the late 70's they made a number of 4" coronagraphs. I saw one at local...

Hi Mark, "Life" got in the way again and I forgot to phone my machinist friend. I'll do so today, and I'll also try to locate any photos I may have. -- Kenpo...
Phil, Isn't there a new filter specifically made for suburban light pollution? I hate the thought of that lovely RV-8 getting all those unneeded wavelengths. ...
... You're best bet is keep an eye on Astromart, e-bay and this list. Those scopes do show up, though less often the RV-6. - Roy BTW: What does RV stand...

Did you all see the RV-6 for sale on ebay right now? It looks to be in very good condition. ...
I don't know what it is about these scopes. I have an Orion x10 and a Celestron 8i. I have found out that I just like the Newts. I also have the Orion 6inch...

It almost sounds as though you have a clock drive from one of Criterion's Custom Dynascopes. The worm gear, and hence the housing, was noticeably bigger than...

They are definitely 1 and 1/2 inches in diameter. It may be a custom mount. Very sturdy but I wish it had slow motion control on declination. Thanks! Guido ......
I think you are right because the mount is larger than the original. It is funny because back in the 70s I tried to buy an RV6 but it was too costly to ship...
