what CCD ?

1102? what is that?
Excuse my ignorance

I have an Optec focuser on the Tak which I think brings the focuser down to a 2", though I think the original tube is 2.7"
I like the image scale of the Tak so that would be my main scope I think, though with a Moonlite fitted to the 10" Newt and an MPCC I will be experimenting with that as long as the mount holds it.
My seeing is mostly crappy anyway hence the OSC idea.
Is there an OSC with intrinsic guider with an 8300 sensor?
How does the 8300 size compare with say the Canon DSLR (60Da) sensor for size?
is this a step up from my QHY 8 OSC (old style ) with the "APS sized" sensor?
7.8x7.8 um ="6.16um mega effect pixels according to blurb

My Atik 314L+ has the Sony ICX285AL Exview with 6.45x6.45um pixels (1392x1040) - I would prefer a bigger sensor as I find the image scale on the Tak slightly small.

The image circle with the optional reducer or flattener for the tak is 40mm- but they are quite expensive.

Cheers for the good advice thus far chaps..
