Thank you for the info.
Google was not helpful about the combination of Meade F6.3 reducer and RC8. I found only one comment that "it works".
I have decided to get the proven CCDT67 (or the cheaper clone) after reading that it will also work well with my f=600mm ED80. I wanted a larger field for some objects and was contemplating a reducer for a while. Two for the price of one
Glen, the reducer on the RC8 will give an
OPTIONAL second (faster) focal length that is roughly half-way between my ED80 and RC8. It is also easier to step up the guiding from 600mm to 1200mm than jumping straight to 1600mm.
And arguably 10" f5 Newtonian is pushing the limits of EQ6, even the CF version.
