Are you sure it's a DK.  Cave may have made its own Classical Casses.

 

One of my 10" DKs has Tinsley optics.  The other one is unmarked, probably from the early 60s when they seemed to not always have signed them.

If you look close the mirror is scribed DK.

The CC utilizes a parabolic primary, in which case it could be made at F4 or F5 and used in a convertible Newtonian-Cassegrain. Didn’t Cave make some of those? It seems like I ran across one in southern Cali back in the ‘70s. It might have been a custom job? Maybe a 10”?

I picked up one that had belonged to Miami University from the flipper for one of our CN members. I took it apart, packed it, and shipped it to California. I think it was maybe a 12.

I always found it amazing that a chip that is 0.25% of the total area of the lens causes a 50% drop in the value of the OTA.

I once got a 90% drop in price on an optic that has a chip affecting 0.6% of the area grin.gif

Go for it   at that price it is a great anything scope   scope for grab and go  scope for outreach  scope for kids  scope for camping  travel  I'd take it on the boat vacation     oh know I just got a wee scratch on my classic      no matter  cuz after all with that  wee  little imperfection  it is so discounted it would almost not matter what ever happened to it .....the idea that you could use such a good quality refractor with limited worries . cries out for  bringing it home       sometimes a scope finds you

That's an impressive almost empty bag.  And is that depression in the grass a transposition of the dark loop around Betelgeuse?

A big scratch  on  the OTA would do the same, and not impact the optics at all.

I think that is far better, actually. The scope has a home and a user who appreciates it's capabilities and benefits from them, rather than one whinging Joe Lookastar after another fiddling with it before passing it on to the next - horrid life for a scope for no good reason. 

 

Anyways, the Telemental II already has an offer pending so darn and double darn. 

 

Western Field Astronomical Telescope Made in Japan Vintage - either Circle T or Diamond Z - I think Towa, but won't swear to it. I have an orange one. It is very nice. Yoke mount, wooden tripod; yes you could do better but you might have a strange need for a Western Field... here's your chance, Wild One! $59.99 plus shpg.

 

Vintage Meade Heavy Duty Equatorial Telescope Mount & Tripod for 80mm & others   Meade CG-3 equiv. $100 + $25 shpg, and I am tempted, but not in need. 

 

Vintage Edmund Scientific Astroscan Telescope With Base   25mm Sirius plössl incl. (meh) but the primary looks okay in the pix, it has a base - $62 + 30shpg to me, ymmv.

All i see is a bag laying on the ground.  The Nishimura Newts were the best looking over built Newts of all of them back around 1961.  Nothing comes close to the build today. I would kill for one.

A couple of nice items from one of our own here:

 

First, the very rare Vixen Custom D alt-az mount. I had one of these counter-weighted alt-az mounts for several years in the early ‘00s. They are very robust for their size. Mine handled a Stellarvue 102mm F7 apo handily back then. They have great slow motions, and are much more stable than the regular Vixen alt-az of the time. They also are great with the Vixen BT80 binocular telescope.

Next is an equally rare 6” Intes Mak that looks Mint! Complete with finder AND focal reducer!

 

https://www.cloudyni...t-150-wreducer/

 

Both items are attractively priced for quick sale. I wouldn’t hesitate if you’ve been looking for either!

Always in PA.  I'd buy that even though I don't need one, if it weren't 3000 miles away.
