Brett,
It is a real struggling trying to find a good telescope camera combination.
Personally, I would go with either the...
QHY12 with its 5.12 icon pixels it gives ~2 arctic/pixel.

Atik 490EX at 3.69 giving 1.44
Atik 460EX at 4.54 giving 1.77

The QHY is a colour, the Atik's can be either colour or mono. Just my take
Cheers,
Colin
