I'd like one but not at that price!

Are they really as rare as the seller makes out?
I would have thought they would have made quite a few hundred at least otherwise it would not be worth the development costs of producing them?

Really? what's the point of bidding $10 then?

Hi Alexandra
Well you have never lost any money then :)
In the fine print under the bid box is, "Reserve not met".
This means, you gota keep throwing money at it until it disappears. Then if no one else bids it is yours!
You can be sure the reserve is not low.

It seems to me that a used CaK PST should be worth quite a bit less than a new Lunt CaK 60mm telescope. After all, the Lunt module allows it to be easily used in a larger aperature scope. I guess in theory the PST has slightly narrower bandwidth. The B1200 module I have is super easy to use on most telescopes and is very imaging friendly. My old H-alpha PST was not very imaging friendly and I assume the CaK PST has some imaging issues as well (right out of the box at least).

That is silly. The same bidder that placed the first bid placed almost all the rest too. OMG what people won't try and get a way with.

I guess the bidder is from seller…
Hmmm, I thought that was against eBay regulations.

However it's going to be impossible in practice to prevent a user registering multiple identities or groups of users collaborating. I have a nasty feeling it happens a lot. I gave up using eBay auctions for this reason ... I do buy new stuff from "eBay shops" using the "buy it now" system but I do have a very clear idea of what the stuff is actually worth.

I guess in theory the PST has slightly narrower bandwidth. The B1200 module I have is super easy to use on most telescopes and is very imaging friendly. My old H-alpha PST was not very imaging friendly and I assume the CaK PST has some imaging issues as well (right out of the box at least).
I have a PST CaK and a Lunt B1200 CaK diagonal. Not sure about "narrower bandwidth" ... I need more gamma / contrast when imaging with the Lunt but the difference is not huge.

Yes, the PST CaK has the same focusing issues as the Ha version ... but you should be fine with a short shoulderless nosepiece on a CS mount camera.

The big issues here are:

(1) against the Lunt diagonal: hard to get a full disk without a focal reducer, unless you have a large chip camera. (That's why I keep my PST CaK.)

(2) against the PST: the image is much dimmer, making closeups difficult as long exposure times result in unacceptable image degradation unless the seeing is "exceptionally good" which hardly ever occurs at CaK wavelengths

(3) against the PST: the usual issue with astigmatism from the prism assembly.

(4) against the Lunt, with some scopes: the long fat nosepiece may not insert fully into the focuser due to interference with baffles in the scope. This can make focusing impossible.

The PST CaK is a great wee scope for full disk imaging with something like a DMK41 and is so light & compact that mounting issues are non existent. Otherwise the Lunt CaK module (used with an existing small refractor) is preferable IMHO. That's independent of pricing and availability issues.

The Lunt CaK scope package is not particularly good value IMO: I got one (with the standard focuser) & it's OK but the optics in the 60mm objective are "generic Chinese quality" & the focuser (which is very clearly a generic Chinese Crayford) is just about usable ... it would be much better with the Feathertouch focuser but that makes a much impact on the price. If you have a halfway decent small refractor without baffle ridges in the focuser then the Lunt module is the way to go IMHO.

Edit: And if you can get the straight through version, it's much more convenient than having a disgonal "in the way". Cameras don't get neck strain and CaK is not really an option for visual work.
