Anyone see the new Orion 7.1" Mak-Cass that is on the 2nd page of the most recent US Orion catalog?

smile I've seen it!! It's something I've always wanted!!! I've just bought an ORION Atlas 11 XLT SCT, though!! This is their C-11 OTA w/XLT coatings on a beefy Atlas German Equatorial Mount. ....a pretty neat scope I must say!!! So now, I can't afford one. So far, however, the C-11 is just fine for me. I used to own a 5" StarMax 127mm mak-cass and totally loved it!!!Then I drooled over the new SkyView Pro 150 6" mak-cass, but never got one! (Sold the 5" to help pay for the C-11 Atlas.) So it seems that now that the 7" mak-cass is out, I won't be seeing or getting one of those anytime soon! I'm kind of sure it'll be as great as the 5". I still haven't heard much on Orion's 6"(150mm) either! Any reports out there!!!

This Mak is the Synta made maksutov Cassegrain and we sell it here in Germany already since a few monthes. It is the big brother of the smaller 150 mm Mak, same thing, just bigger

How large is the central obstruction -- looks small in the
photos? Is there any method for cooling it quickly - fans
etc. - did not look like it.

I do not wish to bad mouth Chinese over their quality control issues, they have both disappointed and also surprised us with their products.
That said I am curious on one issue regarding their 180 Orion Mak, unlike the Meade Mak which came with a huge obstruction this one comes with a very small spot secondary, mechanical issues aside, in the optical department, given the design, a Gregory variant, this particular Mak will require a good bit of aspherization to perform well on planets, that is my $1200 question, can Chinese really pull this one for the $$$ charged? This is not an easy task and I am not sure if machines can do it, let us hear about it.
