I still don't understand why AT began the sales talk of these telescopes before anyone else came up with there copies (GSO, Orion) for sale and Astronomics still doesn't have any to sell while it seems everyone else has them in 6" & 8" sizes white and black?  And Astronomics still after all this time can't even give us a sales page showing anything on the 8" version.

What's up with that???

I suspect that there's more going on than simple shipping issues. I believe that given the volume of business and past relationship that Astronomics carries more weight with GSO than just about any other distributor, so not having these CC scopes suggests to me there's more to the story.

Not sure yet. To be honest those two sizes were a surprise.

So how would the cassegrains in this thread stack up optically against the ones from this company?

GSO vs. Zambuto or Takahashi Mewlon, a really big difference.

But most people are interested in lowest cost so they will never know what a difference optical quality makes.

I understand, but curious how reviews of these new cassegrains have compared to other makes available.

I have found a detailed and interesting review on a Japanese site of Kasai Trading's GS-150CC telescope which is essentially the same as the GSO, AT, TS, Orion (USA) 6" F12 Classical Cassegrain. Google translation does a decent job of making it an easy enough read:

I thought it may prove interesting and useful to some and hence I am sharing it.

Some people have compared  Zambuto and Mewlon side-by-side to less expensive imports for months and found the differences were subtle under their seeing conditions.

Yes, for larger apertures the differences are very subtle in typical observing conditions. Where premium optics shine are in smaller apertures in all conditions and in larger apertures in excellent observing conditions.

Here's an image taken with the 8" CC. M63 LRGB 4 hours of 5 minute exposures using the AP CCDT67 reducer.

I did replace the focuser with a Moonlite for better collimation.

Astronomics hasn’t started shipping them yet according to Michael’s last report here.

With the relentless dew this summer, the idea of owning one of these is becoming better and better.
