Im not suggesting mosiacs on a 3200 or 6303 are actually prefered over a 16803 for large FOV, just that they dont seem to be as painfull as I thought.

OK, well, a 7 pos wheel is a handy size, would take the full LRGB Ha SII OIII. Since 80% or more imaging time is at Ha, thats where the Qe counts (for me anyway), unless you image more Lum for galaxies etc, but then exposures are much shorter anyway.

The value in going below -20deg has been argued before, lower is better of course, why not if you can, but Im still not sure its THAT important.

The 12.5" RC will take the 16803, but not the 10" ive been told, so along with changing everything else in the optical path, thats a serious amount of money, hence a long list of excuses to avoid it ;-).

Yes, NABG can be difficult, but I havent found it so much of a bother actually.

That file size is frightning, certainly my PC couldnt process them, so thats another PC, although thats not so expensive now adays.

Anyway, ill give a mosiac a try and see how it goes.
