I can think of a few good colour CMOS sensors
Hi Colin,
I have the WO reducer/flattener 8, still sitting there unused in its box since I bought it last year - it's BIG, too big, in my opinion for the WO GT102 (with which it is entirely compatible, according to WO), and IMHO, almost guaranteed to cause tube flexure in what is only a 4" telescope. I suspect I will sell it and buy something smaller.

As I have just discovered, sensor size is not everything, (pixel pitch, well depth, etc seem to be more important), but I guess a sensor of APSC or four-thirds size and up to full frame, would be great (and with a weight under 600g?) CMOS sensors are gaining ground (like the one in the ZWO ASI1600MM), but there are those that say CCDs still have the edge for overall image quality.

Would love to get some suggestions from you - and thanks for your reply!

Cheers,
Richard
