6" Edmunds Scientific F8 Newtonian
      #30988 - 12/19/03 11:47 PM

Did anyone else ever have the pleasure of owning one of these? My father got me one from his company (Owens Corning) after using it to measure pollution in a steam plume at a local factory. It had a pier mounted eq mount w/clock drive and setting circles. I had the most fun with it. What remains is out in the corn-crib of my brother's barn, and I have been considering having the mirrors re-aluminized, and coming up with new counter-weights, and setting circles. By the way, one summer night many many moons ago, my younger brother and I broke out the Red Spot on old Jupiter with this pieve of glass. Please respond.

Have you posted a picture of it? I'm a long time Edmund Scientific Fan. Lived near Barrington NJ back in the sixties and seventies. I still have my 1977 Red Tube 6"f6 on the EQ Fork Mount. There are pics of it in the forum and in the photo section. Edmund was the neatest store, it was a shame when the retail division was sold. Walking through that store back then was like dieing and going to a tinkerers heaven.

Ken, I would ashamed to post a pic at this time. It;'s spent about 25 years in the barn (which had chickens in it, can you imagine), and then in the corn-crib. I'm gonna have to sink a fair amount of bux into it to get back up to snuff. When I've done that, yeah, I'l post a pic.

Some guy donated the 8" model to our club about 10 years ago. Took it apart, cleaned it up and put it together. Great scope.

Topcat,

Yeah, when I get started, I'll take many many pics. Clear Dark Skies!!! AS a matter of fact, I'm wating for the dew to evaporate from the corrector plate on my Nexstar 8. WW

Anyone know where to locate a 'clock drive' (RA motor and gear set) for these EQ mounts? I friend of mine recently dug his old 6" out of storage. His dad gave this scope to him when he was a 'wee lad'. Since I'm experienced in telescope building (and know one end of a screwdriver from the other) he asked me to help him fix it up.
Main mirror and secondary were toast, so we replaced the main mirror with a new one and made a 'curved vain' secondary holder and purchased a new mirror for that too.
We kept the main mirror mount (it's well designed and built) as well as the focuser.
He repainted the tube (inside and out) as well as the mount. Put everything back together, collimated and it works great. :-) Now he wants 'tracking' so I need to locate the 1" shaft gear with motor.
Any help in locating one, is much appreciated.

Thanks

Bill: What made you decide that the primary and secondary were toast? Were they chipped? cracked? Inquiring minds want to know!! The worm wheel, worm and a stepper motor can be had from Apogee (www.apogeeinc.com). THe last I saw the package was about $100 bucks.

Bill,


Make me an offer. I've got one, and might be persuaded into parting with it. Pete

Did anyone have any luck finding an AC motor or other parts for the Edmund mount. I have contacted Apogee repeatedly via email with no response back. All I am looking for is the AC motor. Mine is a bit tempermental following damage it received in a hurricane leading to the restoration.

If you really want to use that motor, take it to a local motor rebuilder. You may have to look around for for a shop that will work on something that small, but I'm sure someone will be able to do it. If all it needs are bearings or rewinding, that pretty simple. You also may get laughed out of some places as these guys will prolly not understand your motivation in trying to FIX something so small. All small motors today are considered disposable and are not made to be fixed. But it is an option for you.

here is mine from 1978 and it is still in good shape, actually rivals the meade lx200 8" and celestron 9.25" (sharpness/contrast wise), except no GOTO which I am looking to try and make one for this mount. Oh yes and I did try a panoptic in this scope a while back and what a view.

They are beautiful scopes. I know they were/are expensive for their day, but after using them, I'm not quite sure why the idea of all those 6" and 8" dobs seeems like a good one? I just don't see right now how any quality company could manufacture telescopes like these with all the chinese dobs and inexpensive Meade's from China flooding the market. There would always be a few of us that would buy new Edmunds over their less expensive counterparts in much the same way some of us by the little Q over ETX's and other inexpensive Maks. But would there be enough of a market for true high quality 6'f6 and 6"f8 and 8" f5 Newts on GoTo equpped forks like these. And then how much would someone be willing to spend. $1000.00, $1250.00 $1500.00?? At say $1500.00 could a company even produce one of these telescopes. As an example the 6" f6 was $499.00 in 1979. Adjusted for inflation that would be $1325.00. To insure quality components and the added goto we could easily drive the price to $1500. or slightly beyond. I might be willing to to pay that much for a quality 6"f6 Goto on the Edmund fork, but would anyone else?? (It has to have the famous red tube!! ). And the figures on an 8"f5 are even worse. That telescope was raised to $799.00 in 1979, equivalent to $2120 dollars now. Even I admit that that would be a hard sell to convince someone to put out that kind of cash for an 8"Newt. My thoughts anyway, after the years of dissapointment with the plethora of inexpensive dobs and other Newts.

Guys if memory serves me I believe Bill Vorce has these motors in stock. http://www.astronomy-mall.com/telescope-warehouse/ He was asking like $25-30 bucks and they were new old stock. Good luck. BTW I lost out on the 8" fork mount on the "auction site" last week. Congrats to the fellow who won it, If I wasn't sooooo cheap he would have been in peril. Such a cool scope! Enjoy!!!

fx....

Thanks for the information, I could not find it on their site nut I sent him an email. The guy who won it is also on the board. I'm looking forward to hearing about the scope when he gets it. I drooled over that 8" myself when I saw it on ebay.

I recently picked up an old white Tube Edmunds 6inch F8 on a non-driven EQ mount. The scope was disassembled so I got a pretty good price. It went together cleanly, it was all there, the focuser needed some lube, it needed collimation but other than that I didn't do much.

Optically it does a nice job, nice aluminum primary cell, made in USA mirror. Single stalk secondary with a 20% obstruction, "refractor like" was the term that came to mind at first light.

Now the mount, the mount... well, I think it has a natural frequency that is tuned to the primal rumblings of the earth so that it never quits shaking. Bought some tube rings to put it on a modern EQ mount, see how that goes as soon as the sky clears up.
