Wrote a lengthy article about Criterion
      #5545873 - 11/29/12 05:21 PM

I sent a lengthy (14 page) article about my time as a Criterion employee (1978-1985).

Anyone know how long it takes for articles to get approved? I think the forum regulars might really enjoy it.

Thanks,

Gil

I'm optimistic, but haven't got confirmation E-mail yet. I included half a dozen photos of the shop.

That's a nice looking 6" scope, there. Those scopes have a near focus of like 10 feet - long distance microscopes!!

The article may not answer the types of questions that you may have, but when it gets published, if anything comes to mind, just ask.

Gil,
Very much looking forward to your article. If you post a few paragraphs here I'm sure you'll find some eager readers. I'd be curious about how things were inside Criterion during the change of owners and the West Hartford vs. East Hartford facilities.

That's exactly what my piece is about - from the point of view of an enthusiast, what my impression of the sale of the company was like. Along with as many details as I could remember about optical and mechanical fabrication.

Got the Cloudy Nights E-mail confirmation this morning, so I'm optimistic about publication. The group here was my target audience - so this is the best place for posting of the piece.

That should be fun to read! Did you hear some interesting history of the early years too? (that would also be fascinating to me.)

You were there a little after my time. I was there around 1968 as a 13 year old to get my first scope with my dad. Talk about a candy store for geeks. Scopes, mirrors, machine tools, shop smells. Ahh!

Gil, now I know why you asked.

I actually used a Golden Pyramid Tripod for my C-8 once it was out of the observatory. I really like it (only issues I had was lat adj, but a turnbuckle handles that and a spreader that broke one spur and I replaced it with one from a Celestron tripod when I got back into things.) and recently picked up another in very good condition.
Can't wait to see the article.
Brian

I wonder if it went through? They usually process them quicker than this, You might want to re-submit it.
Or at least PM a Moderator to nudge the process along.
I love the Index card story...

Are you referring to how we kept a record of each scope's optical performance on index cards? How did you hear about that?

Hi, new member here. Can't wait to read your article! I have a B&L Criterion 4000 that rewards me with razor sharp images - after aligning the secondary mirror and collimating it - definately a keeper.

Nice to hear their story - from an insider.

I have only one Criterion product - a 4" Dynascope. While produced before Gil's time there, I can almost imagine that the shop didn't change much.

Thanks for the story, Gil!

Interesting article. It's a shame this sort of thing is no longer economically viable, America could use more mom and pop enterprises but it's all overseas now. I have a 4000 and its a usable scope. Ive always wanted to buy a decent tripid with a wedge for it but I cant bring myself to spend the money on it as it seemed a silly investment all things considered.

Bought my RV6 around 1960, can't remember exactly. Took it out tonight and had a fantastic view of Jupiter as one of it's moons was occulted. Loved the article about the shop. As a young kid I figured a bunch of engineers in white lab coats were building these fabulous instruments. Interesting to learn the reality. Thanks, Bill

Nice job Gil - thanks for that. Loved the article and photos. Excellent look into the past at a once great American company. I always imagined it a much larger facility. How many RV6's do you think Criterion got off the line?

Gil,
It was interesting to read that Criterion made it's own mirrors since many times it has been reported that UPCO made the them and Criterion purchased them from them.
I bought a numner of spare parts at Stellafane from the former employee you mentioned in the article.
Could you discribe more about how the optical testing was done with artifical star made by using a laser ? What did you look for in the image ?

With the assembly bench and a 4mm eyepiece, we could exanine the airy disk and first refraction ring at focus.

We did buy the occassional RV-8 mirror from Upco, but the RV-6 and Dynamax 4, 6 and 8 mirrors were all made in house. Not sure how often we sourced RV-8 primaries, we hardly ever shipped them. Well less than 5% of the Newtonians I built were for RV-8's when I was in that area.
