Has anyone managed to find out if or when these scopes will be going on sale?
They are on the ZWO China website, but not in their online store, and no other info seems to be available?
Here is one page from the website with some info:

Their Aliexpress store does have the mirrors for sale up to 305mm, but nothing on the scope frames themselves. Reading the specs I tend to believe that a GSO mirror would be a better option, if they would sell the frame bare.
