On closer inspection I see that mine is brass. I also found it in the 1965 Edmund Catalog (item #50025, p. 21) selling for $4.25, Ppd. I also see a focuser on the same page that looks the same and is stated to have black wrinkle finish and chrome tube for $8.50 Ppd. doesn't say knob color but it sure looks the same. Seems I bought the two together?

Terra,
Jaegers was known for having the red knobs on their focusers while Edmunds were smaller in diameter and black. I have a couple examples of each and the Jaegers units all have the red knobs so I'm pretty sure you purchased the focuser from Jaegers.

Mystery solved. Edmund supplied the diagonal spider and mirror kit, and the primary mirror cell and focuser must have come from Jaegers. The finder, of course was purchased new from Unitron, tube home made. The eq. mount and wooden tripod, (still to be located) came from Edmund. The rings were bought second hand at RTMC. The tube was homemade.

Terra:

Where was RTMC held when you bought those rings? They look like Pacific Instruments rings to me, which would mean that you had the tube made to match the OD of fiberglass tubes from Parks?

Hi Tim, those rings were bought at RTMC up in Big Bear in the early 80s. They replaced an older plywood saddle with felt lined aluminum hose clamps. That saddle bolted to my Edmund eq. mount. It was very hard to find rings to fit my tube. I had the tube made years earlier at a local sheet metal shop. The tube is 7 inches o.d. and apparently that is an odd size. The front cap is a sort of rubbery plastic and it was purchased at the same time as the rings but from another person. Both were in the used/swap and shop section.

After getting the rings I had to make a steel plate to bolt them too. The rings are unusual in that each one bolts to the plate with two 1/4-20 hex bolts. The plate is 2 1/2 inches wide and 8 inches long. It is drilled and tapped 1/4-20 with two holes that allow it to bolt to the end mount mount. Also, the rings are not hinged. They are different. I haven't ever seen any others exactly like them. They may have even been ATM'd but if they were, they were well done.

That photo --cradling the scope--- is absolutely priceless. You should write an article for CN about this adventure.

Wonderful Terra.

Thank you Mr. Bear :bigblush:

This was the original inspiration for my telescope. It's on p.6 of the Cave catalog and billed as the Astrola 6" Richest Field Telescope. Interestingly, the model in the picture is also "cradling" a scope in her arms as well. The Cave scope was F4, mine was F4.5 but the final figure was still Cave. :)

That is a great idea!! Not like we're trying to toss you under a bus or anything Terra. :whistle:
I had a couple of those PVC caps for my RV6 ordered them from who knows where. They were floppy when it was hot.

You might be in for a new carreer Terra. Modeling telscopes like the girl in that cave catalog.

Hi Terra, I just had to chime in and add my comments to your incredible reunion. What joy! The moment I saw that picture of you cradling your RFT, it made me think of that model you describe in my old Cave catalog. I’ll have to admit, that picture has so much more impact and class when the person holding the telescope is an accomplished ATM-er (as well as collector and observer) such as you, rather than just a model (or relative)...

Anyway, your story has hit a special cord in me because I too, in the mid-60's, had started a 6” f/4.5 (aimed for 4, but became 4.5) from my leftover Edmund mirror grinding kit supplies. I got it fully polished, but never had a chance to figure it by the time high school and college took over. So looking at your finished product gleaming in your arms is touching, and an incredible source of inspiration for me. Your pearl white tube is beautiful; by the way, I was able to get a 7” OD aluminum seamless tube from Optica b/c in Oakland for my 6” f/10 (c.1965) – but it may have been their last piece, as it was squashed a little at one end – I had my huge friend stomp on it back to round!

Also, thank you for including the link to the catalogue. I stupidly threw mine out :bawling: after I bought Cave’s mount in the early ‘70’s, and haven’t seen one for a long time – it’s so nostalgic. I remember mine having a more pink and white background with a younger model on the cover (maybe a later issue?) but the contents intantly brought back all the memories.

Happy Mother’s Day!
Great post! :bow:

Note the finder still has the 'Passed Sticker" from the Japanese Telescope Institute! How cool is that. Purchased in 1966? Right out of a time capsule!


Congratulations on your family reunion. That is indeed a special scope. I've enjoyed sharing the journey with you.
:thewave:

Also, thank you for helping me resolve a mystery regarding the Oval gold foil JTII stickers! I have several Celestron eyepieces with that very same sticker. I was pretty sure that they were from the mid-1960's and your finderscope story confirms it for me.
:jump:

In the post following the one that I've replied to there is a symbol next to the focuser. What does it signify? Is it a logo?
:question:

Thanks, again!

Terra, what an astonishing story, I think the best here, ever. And what a wonderful mother's day gift. That slick reddish-cover catalog brings back memories, I believe it is identical to the one I had, maybe the same issue. I remember the picture with the 6" RFT, and especially the one on the back cover with the 8" model B deluxe, that was my ideal. Then I looked in the product list -- 6" mirror refigure for $35. I had mine refigured and remember the price, must be the same catalog. I had one of the 6" f/8 Edmund mirrors from the "bad" period and had to have it redone. Came back one of the best optics I've ever seen. Interestingly, the coating on it is still good after about five decades (in a not-good environment, chemical plant only a mile away for many years). I wonder why there is so much trouble with coating durability these days, they seemed to know how to do it then.

Hi Blake, that isn't a logo by the focuser, its a foil sticker of a crescent moon and star that my daughter gave me when she was 6 or 7 years old (she's now 29) from a page of stickers she got. We put it on the telescope way back then and its still there. :)

Hi Tom,

The mount I originally had for that telescope has not yet turned up. However, it was in the same storage lot and is probably in another moving box in my friend's basement. It will take another trip down to her place and going through a bunch of boxes to turn it up if its still there. We will look for it at some point.

Actually, the first mount was an alt-az pipe mount on a 4x4 pier designed after one in Sam Brown's Edmund Book about "How to Build a Telescope." That mount rode on the pipe threads and is long gone. It was replaced not to long after the telescope was built with an Edmund Mount (the one presently hiding in storage). That Edmund Mount was the same one as they supplied for their 4 1/4 F10 reflector, except it was on a short wood tripod (Edmund), and had a longer stainless steel counter-weight bar that a friend machined for me and two of the counterweights rather than the one that came with the mount. The extra Edmund counterweight and longer bar easily accommodated the heavy 12 pound OTA.

As that mount is currently missing, I will have to improvise. The rings of this telescope have a wide base and each require two bolts rather than the customary one. I had a wide steel base plate machined for them (about 2 1/2 inches wide or so). I will bolt a short Vixen dovetail rail to the bottom of the plate and then I will be able to use the scope with my Universal Astronomics Unistar Deluxe mount and heavy duty steel tripod. The telescope, being primarily an RFT does wonderfully on an alt-az mount and that mount will very ably handle its weight. it's the same mount that I use for my 5 and 6 inch F5 refractors.

I will post pictures when I get it mounted and of course, when I lay my hands on the old Edmund mount.

Well, I got the scope mounted today and looked through her for the first time in many years. Just looked at tree tops, telephone insulators, etc., checked the collimation, aligned the finder etc. Still presents crystal clear, sharp images using a wide field 19mm eyepiece to yield ~35X.

I still haven't been able to locate the original Edmund Eq. mount, but the scope's mounting plate had a row of five 1/4-20 tapped holes down the center, designed to allow for balancing. And I just happened to have the perfect mount and tripod for the scope. And guess what, the mount head is 1/4-20. :)

The mount/tripod is very stable, has smooth alt-az motions, adjustable tension, horizontal and vertical locks, is adjustable height, and best of all, it is perfectly consistent with the age of the telescope (1960s).

These mounts were available to ATMers back when I built this telescope, though I purchased mine many years later. It is an American-made (NY) Professional Jr. 16mm motion picture camera tripod like those used to make the old time news-reels. This one was military surplus and dates to WWII.

I always thought that an alt-az mount would have been perfect for this scope. Now it has one. This will be its dedicated "ride." I'm pretty happy with it now, just as it is. :)

Awesome combo Terra. I saw an old Emunds mount on either Cloudynights or Astromart today for $125.
