My "guess" is that the apo is a Petzval, otherwise they've created something that I do not believe has existed to this point. I once got quoted $80,000 for an 8 inch f4.0 apo by the Russians, that was 20 years ago.

Questions though; is the camera cooled and how did they get the Hubble colour pallet, the thing would have to have filters in it.

not the aperture. 1050 divided by 7... 150 mm aperture, so, yes, it's a six-inch telescope.
And its body is made from the alloy Zicral, which I looked up. It's an aluminum
alloy in which zinc features prominently, with magnesium and copper also present. This type of alloy was first developed in Japan, and it was used on the
Zero fighter planes during World War II.

Sounds fancier than aluminum, but perhaps it is for the well-heeled sea-side dweller to mount it outside his house and avoid corrosion?

ordinary aluminum. I presume the strength lets it be built with less metal, so that it
can be lighter to carry.

You can get a triplet apochromat with 80mm aperture for just $1,000.
As for a Petzval, I did find some of those on sale as well - one was under $400, but it
was on back order where I saw it.
Of course, refracting telescopes are not the best buy for aperture per dollar.

John SavardYou can duplicate (more or less) the scope for $15,000 or so, with good quality components. However, you will never match a larger >reflector for imaging at that price-point.

The important point is that by building a functionally equivalent set up you have the option for easy upgrades or mixing-matching components. The imager can be used with different scopes, the scope placed on different mounts, the mount used forJohn SavardYou can duplicate (more or less) the scope for $15,000 or so, with good quality components.

It the imager fails in the advertised scope, you probably have a very expensive door stop or coat rack.
