Hehe!
Only $1600!

The images taken with this scope are as good as a large apo refractor, the only downside of course is the collimation and cooling times but if you take the challenge you can get great images for much less than a big aperture refractor, it always comes out of collimation from the factory but I don't care.

A perpetually out of stock Chinese piece of crap. Check out some of the interferometer tests done on these things. Optics look like a phonograph record.
It's no AP refractor.

Does that include a mount or just the OTA and accessories?

The cost for a new example of this optical tube assembly is shown as $29,600.

A plain-old 8-inch f/8 Newt with a well-made custom mirror could certainly be a reasonable substitute.

Mirrors can be close. I've seen through/owned probably the finest Mak-Newts and Mak-Cassegrains and although some come
close, they don't quite match the best refractors.

I don't know if it's that long for a TEK, and AP no longer makes scopes larger than 130mm. Takahashi makes scopes larger than six inch, but they make the TEC price seem like a used C8 price.
CFF is the new one, uncertain about them as of yet.

Should set up on concrete pier, but of course it will bought some rich condo

I own an old Vixen/Celestron 4" CF APO refractor, I know how good they are!
Showing planets/bright DSOs on star parties with my APO , I all ways had a big crowd around my scope.
But $1.6K vs. $32K is a big jump in price. Not for everyone, I think!
That's why I asked, is that refractor really 20x better than the Mak-Newt of same aperture?
Refractors price jump exponentially as aperture gets bigger and bigger.

Well, he said it was a _really_ nice scope. Of course if your budget is smaller,
you'll have to settle for something more ordinary. Like an 8-inch Schmidt-Cassegrain
instead of an 8-inch fluorite apochromatic refractor.

That one you can't get, it's currently out of stock.

Plus, it's an astrograph, which means its central obstruction is _so_ big it isn't recommended for
visual observing. Not that there aren't _other_ much cheaper alternatives, but this one doesn't
quite fill the bill.

Somewhat smaller (31%) than C8 (35%)?
Mak-Newts come as low as 16% CO.
For larger sensor you want big CO though!

Sooner or later, we might be back to grinding mirrors.

A good reflector, with a couple of more inches of aperture, will be a
better instrument, both visually and photographically, than a
refractor, and at a fraction of the price.

That refractor is going to need a pier or tripod about six feet high in order to get the eyepiece to a comfortable height. That leads one to suspect that this instrument needs to be housed in an observatory. Once you need an observatory, a whole universe of larger and more capable telescopes starts to look feasible, and for much less than $32K. Even the observatory won't cost that much.

Some telescopes seem to demand an observatory, while not really deserving one.

They are definitely not for the weak or squeamish astronomers. Cradling a 7-8 inch tube above your head and loading into the rings is a tad nerve-wracking, compared to handling other types of scopes of the
same aperture. You can now buy rising piers which eliminate the risk but cost a lot. However, if you can afford a premium apo, you can probably buy the pier/mount too.

Lick Observatory has a 16" refractor, but nobody uses it a long time now.
Just a show piece for tourist!
