There, there guys....I'll be the first to admit the image is not perfect ...but it's not too shabby either (IMHO) given the size of a KAF16803 sensor.
Frankly, most systems would fail miserably in off axis performance and mounting such a large CCD assembly...to be sure, these systems are not for the casual imager.
Would a RCOS 82mm field corrector make a difference? I doubt it (gosh...I sound like Kevin '07)
The KAF16803 sensor has "only" a 54 mm diagonal....ie 4mm larger than standard 2" systems. Yet it is easily covered by the 70mm back-end of the RCOS system I currently use.....and given it would require $US6,000 worth of new back-end gear to go to 82mm....nah....a little tweaking in FFC spacing, and polar alignment seems like a better option until proved otherwise
