Does anybody know the history of this company? Is it true that some Questar executives left that company and formed Quantum? If so how are the optics on this scope? Anybody in here have one?
Thanks

Only one photo from one angle which does not show the glass and the seller is brand new with zero feedback.

Sounds a little risky to me.

Regards and clear skies,

Yeah I noticed that! Second time tonight. Seems that anything with potential on ebay could be a scam.
Thanks Mike.

The history you describe is pretty much correct. Company 7 has a detailed write-up about them. Mostly correct, but they are a little diplomatic in describing OTI's downfall. Things were a getting a little nefarious towards the end. The optics were made by the same company that made Questar's. Dad was OTI's Eastern Sales Rep.

100% sure this is a scam. 3rd time in 3 years I have seen this scope.

Although when I bid on this scope for the first scam I never sent the money( I was told near the end it was a scam). Then, a few weeks later, someone who actually had a Q6 in my area contacted me having seen I had bid on the fake Q6. I did end up buying that Q6.

Dad still has a very bad taste in his mouth from his OTI days, even after 30 years and wants nothing to do with anything Quantum. :shrug: He did have a set of 4" optics until recently and just traded them for a scope, but I can't remember what type.

The optics were made by the same company that made Questar's.


Yup, that would be Cumberland Optical.

A couple of things to consider about the Q6.
The silver coated optics might be getting a bit long-in-the-tooth, for a scope of that vintage. Worth checking the mirrors for any signs of corrosion, tarnishing or other discoloration before buying.
The Q6's single fork arm mounting was prone to vibration. Very elegant form.... less than ideal function.

That photo has been on there before... this is probably a scam.

However, Enid is right down the road from me... Hmm.

I emailed him and said I suspected the auction was a scam. I asked for additional photos, or some kind of evidence that the scope was in his posession. Needless to say I haven't heard back yet!

Well. looks like this sucker just topped $11,000 with just under 5 days to go. Sorry, no sale. Don Yeier had a pristine Questar 7 up at his booth at 2006 NEAF for under that. IF this is legit, the bidding has gotten way out of hand.

Although optically identical to a Questar (I'll have to check that '1/20th wave at the EP' stat though, I'm not so sure about that) mechanically there is a wide gap in construction. If I remember correctly, a Quantum is baffled with the standard baffle tube and flocking paper, the Questar uses something like 17 knife edge baffles. The Quantum 4 and 6 use the focusing belt, while the Questar 7 uses roller bearing focus and has NO image shift (the control box in the 3.5" was too small to incorporate that, though). Optically the Quantum 4 outperformed the Questar 3.5 due to the extra 0.5" aperture. I remember being one of the first to witness the side by side testing...great fun for an 11 year old.

All that aside, would I still want a Quantum? U betcha.

I believe this is a war between concerned ebayers vs a scammer. They are just bidding up the price so that no unknowing bidder will actually try to buy this. Since it is a scam, the scammer has no recourse because he can't produce the goods. The bidders have no intemtion of paying out any money because they believe this is a scam. It happens a lot.
The real question is why hasn't ebay pulled the auction. (Unless of course no one has notified them)

I don't think I've ever seen any Quantum going for over 3K.

John,

Interesting explanation for the bidding we were seeing. Makes sense.

I first heard about this technique with the scammers from the oldscope forum. You need two people to bid up an item into the stratosphere. They usually do it from an ebay account they setup to do this exact thing.

Apparently antique telescopes are a favorite target of scammers. Alvan Clark refractors especially. I have seen the same Clark refractor on 4 or 5 bogus auctions. As soon as someone notifies ebay, the auction will be pulled, just as what happened in this case.

Well, a quick OTI/Quantum update for those who might be interested.

From a guy who sold them...the Quantums were not specifically spec'ed for a certain wavefront at the image plane, but Zygo interferometer testing usually showed 1/10th wave. OTOH, during the same round of testing, a 1971 Questar 3.5" showed 1/20th wave at the EP. Also, although the optics were both made by Cumberland, the primaries on the Q 4 was f2.5 and on the Q 3.5 is f2.0, so the Quantums weren't just bigger versions of the Questars.
