Insane price on the AP. The 6"  D&G is priced very good.

Yes, you can buy a Star12 for about that much if you are lucky.  The 102 is pre-ED.  But as for 4 inch scopes, check out what some Travelers have gone for recently.

If I lived in NJ, I could have had a C8, 

 

For $50

I'm very sure the $50 in the title is just a come on.

The description says best offer.

And if Facebook is like Craigslist you need to include a price in the title.

Silly AP prices when a Tak at near half the price does just as good.

Has this beautiful project telescope already been listed here?  I just found it, looks like something I'd be after if I lived closer. . . . .

Yes it has, but it was a few years ago.

Re Stewarts ad:

 

What model would the "6” Astro Physics refractor on losmandy mount (older) and tall tripod" most likely be?

 

Maybe I should pay him a visit (I'm 2.5 hrs away)...

Less important than if the Stowaway is an original fluorite model.

Yeah, I'm in touch with him now, he says the 6" AP is vintage 1990's or so. So that would make it a 155mm f/9 if I'm not mistaken, and I have no idea of what glass AP was using back then.

And the Stowaway, he's thinking now he doesn't want to sell it after all. Go figure...

Better, fluorite vs. pre-ED glass.

[bobhen]

Better, fluorite vs. pre-ED glass.

The late 1980's pre ED triplets were just as color free as the Tak Fluorite doublets. I owned an AP 1989,152mm F9 triplet and don't remember seeing any color, even on a tough target like Jupiter.

 

The AP ad below states "essentially" perfect color correction in the visual range from 4000 to 7000 angstroms. Not as perfect as AP's later FPL 53 triplets of course. But Tak Fluorite doublets were not perfect either and they are not nearly as perfect as Tak's later duel ED lens Fpl 53 TOA triplets.

 

If anyone runs across a late 80's AP pre ED in good shape and for a "good price", you will not be disappointed in the visual performance.

Thanks for posting that link.

 

I had already spent some time on that site this morning. Google was my friend. I would say those old ads are the only way to see the real history of what AP was up to in those early days.

 

There's also this:

I have been enjoying those ads for years.   Wish I could buy an AP for what they sold for in 86.  We would all have one.  Even the early triplets were fantastic performers I used to have a 6" AP.  Roland claimed they equaled or exceeded Fluorite lenses.

I have one of those 152 triplets from 1988 also-I've never seen a hint of fringing on Jupiter or Saturn, even at high magnification.  That's probably why I still have it 21 years after I bought it!  I have a Tak 100 Flourite also.  Why just settle for one??

Almost the same mount as my CI700. Very scary trying to deal with mounting a C14 with a D plate vs the much more easy fork mount.

Maybe just the way the photo is taken but it looks to be a decent size diameter.

The side mounts for a Tasco 9TE-style mount would suggest 60mm.

I'm 99.9% sure it's a DK made 60mm. Same plastic objective cell as on DK made Cometrons, post Towa Bushnells, and others.

Couple of CL Arizona posts that I ran across that might be of interest here...already have a Comet Catcher which is a great little wide field scope. Not familiar with the Sears refractor so passing the link along here. Hope these aren't repeat posts:

The Sears 6344 is very desirable, and this listing at $125 is a good deal. Looks all complete/original with the exception of the little Astronomy book it came with which is missing. To bad the OTA has some very visible scratches / defects though...

Less important than if the Stowaway is an original fluorite model.

So are you saying the current Stowaway's are no longer using fluorite glass? If so when was the last fluorite production run made? I can't find any info online about this.
