QHY9 camera?

Michael,

For the refractors the KAF8300 CCD's are hard to beat. There are quite a number of vendors offering them, ATIK, SBIG, QHY and a few more besides.

Told you I wasn't an expert... I'm getting confused with a Bayer Matrix.

But certainly, some colour CCD's have microlenses - they're not limited to mono CCD's.

The 1603ME has a peak QE in the late 70's (depending on whose data you read). But what strikes me is the technology to get a perfectly formed dome of some material over a little 9 micron pixel. And do that for *every* pixel in the chip. Its some feat alright.

What kind of image scale does that give (arsec/pixel)? And what would your FOV be?

On a meade 16" @ f/10 an ST8 gives 0.46"/pix. You would really want to be binning 3x3. However with the optec reducer (which I know Mike has), that 0.92"/pix (@f/5) and then bin 2x2 and its a very nice 1.84"/pix.

BTW a while back I wrote this little app which makes does these calculations for you.

That's a nice app Dave.
