Very nice article. I love and use my RV-6 regularly. The SCT? All I will say is it's a shame for the people who worked so hard on it that it never really came together.

I agree with you 100%, Rod.

Thank you very much for publishing it. If it is well-received, I might expand the article in the future.

Thanks Gil, I've been waiting for this ever since you mentioned you had submitted it to CN.

A fascinating insight into life at Criterion, really interesting to see the pictures of the plant too. Wonder if you did any of the build of my Dx8 (1980)?

James

Sometime in 1981 According to Company 7 which ties in with the dates for a change in position given on this page on John Krewalk Jr's site, the Krewalks being the owners of Criterion prior to the sale to the Bushnell division of B&L.

Loved the article! I'm a big fan of the Dynascope RV-6 and 8 Newtonians. I don't think I've ever looked through a Dynamax 8, though.

A great story...and a nice piece of history. I was hoping you still owned one

Thanks for taking the time to write such a great piece.

I might have worked on your scope, but it's impossible to be certain. I will say that your scope is my favorite vintage - powder blue arms, white finder, removable finder brackets. I did a bunch of those. The switch to the removable bracket happened when I was an optical assembler.

Good job Gil. Very good article. I have a Criterion Dynamax 8 that is just as good as the one I sold you. That is why I let the one I sold you go. I have bought several of these over the years and played with them. I will never sell the one I have now.

I would not have sold the one I sold you if it did not have great optics, because you would have only been disappointed with it. I resolved the green companion of Antares in spectacular fashion and several doubles, including Struve 359 in Hercules in your scope. I knew that it was good to go. Planets were great too.

A most interesting read addressing the company's background and evolution from a personal perspective. And I must add that my connection with Criterion products dates almost from their beginnings in the telescope business as in my youth I was the proud owner of one of their very early 4" alt-az head Dynascope Newtonians, the first scope the company ever offered, back about 1956-57. I still have its optics around here some place.

Thanks for the inside look at Criterion. I wish they were still in the marketplace. Good quality inexpensive scopes on solid GEMs will always have a place in amateur astronomy. I know I'll always love pushing my RV-6 around the sky.
