I've got the ioptron cem120ec ordered
I'm still not sure how I'll mount my 2 scopes...Would like to do side-by-side, but one is lighter than the other one in weight....And not only is that a problem, but do't have any experience here mounting 2 and 1'st the RASA a catadioptric but the other one's a newtonian and wonder, like what's the difference between (in order to rotate your image, in a newt) rotating the scope around or rotating the camera or your head orientation around...any?
And the other thing is that there may have been be unaligned optics in my RASA...I'm saying may 'have been' because I'm almost certain they're unaligned now...as I've applied a 'black flocked self-adhesive' inner liner to the
tube hoping to cut down on internal reflections...so I'll need to colimate the optics...And there had been though fresh from the factory, a purple equilatoral triangle halo that moved opposite my mount movements...that is op the stars...when moved...And I don't know what caused it? Does anyone know? Wish to get rid of it, of course. Want to fix-up that RASA. PS: hear that Celestron makes a 14" RASA now...but costs about 4 times as much for just maybe 1.6 time the light gathering power...has like 160mm more fl.
Not real serious in getting that one!
Cheers guys! David
