I have no interest in buying one, but there is some info on Celstron's
RASA webpage...
Glass is pretty rigid and doesn't have a great tendency to bend...ask any hyperstar users how they feel about loading up their corrector plate. Besides that, the secondary mirror assemblies in large SCTs aren't exactly light.
The biggest issue with the corrector plate is dew, and that is climate dependent. A dew heater tape should do a decent job of keeping the corrector clear.
And then the "12V MagLev" reduces cool down time (quote), and should keep the internal air somewhat equilibrated.
I'm surprised they didn't discard the corrector entirely and use some nice curved spider vanes.
Fine focus is accounted for with included 10:1 FeatherTouch.
I'm not trying to be smart, just quoting other info that's out there
Whether it all adds up to something you pros want to buy....sounds like a "no", but time will tell how it works out for others when they get out in the wild.
Btw, the picture on their website shows their Nightscape CCD on the front...maybe that's what they envisage people using with it
