I'm all excited to make the switch from my old CCD camera to an ASI294MM pro, and am also switching to a ZWO filter wheel with 31mm unmounted filters. I was using a set of Orion mounted 1.25" filters. I ordered the Baader "CMOS optimized" LRGB filter set- and received what seems to be the older Baader version labeled "CCD" LRGB filter set.

  Am I just splitting hairs here- or is there some real definitive difference in the results I'll get with "CMOS optimized"?

  I've tried to research this, finding that the CMOS sets are significantly more expensive- but little qualifying information available. I'm also using an Optec focal reducer and plan to bin 2X2 with this camera. It would be nice to have all RGB exposures the same length of time- but if it just means weighting them or varying exposures, maybe it's no big deal if that's all this amounts to?
