Very nice work Fred!

At $125 for the 3" refractor it was all the bang (and a few dollars more) for the buck than my family could afford but somehow I got it. That was 1966 and when "show and tell day" arrived in 7th grade I was ready with my awesome Edmund 3" refractor. Of course the presenter ahead of me was Dale Rowzee who brought his 3" Unitron to school that day. Oh well so much for my wow moment and what was a 13 year old doing owning a Unitron anyway... Jerk! ?

I recently snagged a 3" 60's Edmund Objective, and a 1.25 prism diagonal unused from the 1960's. Very fine stuff! I'm just sorry it took me nearly 50 years to realize how good this Edmund stuff really was! At the time I yearned for flexible cables, .965 eyepieces, and an adjustible tripod. While I was hangin' with some of the best I didn't even know it.

Great article. Will never forget the Christmas my mom gave me a Palomar Jr. A couple years later got the 10 inch mirror grinding kit from Edmund, which to this day is the mirror for my main scope.

Ya, got the Jr. for a gift in 1974, my most memorable xmas ever especially as it was cloudy till the end of January!

Thinking about it, I never realized how many good memories are wrapped up in that telescope. Geez, it could be a frustrating bugger to use, but I held onto it till I graduated H.S. and it solidified the hold the hobby would have on me.

At the same time, I don't want another one...gotta keep movin' on!

That would be me~
Thanks for the email too Keith.

I am excited to read this. I will say my initial word search of the document did not turn up any usage of 'Edscorp' or 'Eds Corp' which I'm curious about. Seems Edmund was stamping products with both 'Anchor' and 'Edscorp' early on?

That is a great story. Most of us felt lucky and proud to own any of the "lower end" telescopes of the day. But we all lusted for the beyond our means UNITRON's
Thanks for posting. Bill
BTW I read the enire Edmund article and found it fascinating.

Thanks for all the kind comments! Knowing the article's brought enjoyment makes me very happy It's just been updated with more photos of older items, thanks to Trainsktg, Albert1, Dave Groski and CharlieB!

Refasali, I added a photo and some text on the "Edscorp" and "Edmund Scientific" labels issue; will be looking into it.

Fred

Ir's a 4" but doesnt fit the mount. Will bring it out and wrap a towel around it when it gets warm to check it out.

Very nice! That refractor should have one of the U.S.-made Edmund objectives, as they changed the design of the focuser when they started making their own lenses. I've heard that they were pretty good, although I don't know if they were as good as the Japanese lenses that preceded them.

Edmund optics still sells 3" f/11, 4" f/15 and 5" f/15 achromats in non-adjustable cells. Have never heard of anyone using them, though.

Great article,downloaded and saved.

I need to send you a pic or two.

Just checked and at near $1K can understand why you haven't heard of ATM 4" f15 scope build.

Glad you liked it! Any photos you'd care to send would be great, too.

I know what you mean... if I was planning to use one of their achromats for an ATM project, think I'd choose the 5" for the relatively little extra that it would cost.

I'm very pleased to announce that, thanks to the courtesy and thoughtfulness of the fine folks at Edmund Optics, there are now rare and never-before-seen photographs of the Edmund Scientific retail store incorporated into the article, along with other photos of interest.

Classictelescopes.com - under "Articles"

Enjoy!

Fred

Loved the pictures of the store. Would have loved to spend an afternoon there.
Thanks, Bill

Just downloaded and saved the newer version-nostalgic pics,indeed!

By the way,it looks like CharlieB has already supplied nice pics of the 6" f8 Space Conqueror with clock so mine are redundant. And can't figure out how to get clock (RA) shaft out to clean it up....

Once the 6" is repaired ,and my 76/1200 OTA find is too, wy, I'll be right up there with those "serious amateur astronomers have either a 6" reflector or 3" refractor" as referred in several books.

Fred - glad you included the Edmund Spilhaus Space Clock in your excellent history. I remember spending a lot of time looking over the full page catalog advertisements that first announced it in the '60s, and fantasizing over having one. Since the cost was about 3X my annual grass-cutting income, it remained a fantasy.

I eventually did get one several years ago...with nylon gears, which were indeed split, making the clock inoperable (as an aside, I believe that the majority of the Space Clocks were manufactured with nylon gears, with metal gears being restricted to the prototypes and a few of the first production units.) There is a website (the Sands Mechanical Museum, at www.sandsmuseum.com) that has an extensive section on the Spilhaus Space Clock, including detailed disassembly instructions, and where you can get gears (made of much more durable Delrin) for the defective nylon originals.

Cutting to the chase...with the information from Sands Mechanical, and the replacement gear set, I was able to restore my Space Clock to full operation...it's been operating perfectly for almost two years!

John

Thank you for this contribution Fred! I enjoyed it very much. As a kid in the late 60's and early 70's each one of their catalogs would leave me spellbound for months on end.
