Hello,
I know next to nothing about cooled CCDs, except I probably want one !

. I'm using a Canon EOS 20Da now and hope to increase sensitivity, resolution and shave off rig weight by removing the guidescope by using a self-guiding cooled CCD.
I'm taking my time in considering options and just came across this : QSI 500 series WSG model
Seems to have a self-guiding chip fitted in front of filter wheels
I know the SBiG series offer self guiding and also have larger chip (on some models) than this QSI
Any thoughts on this or other options for cooled self guiding CCD cameras?
It would likely be used on a C14 mainly and possibly C9.25 on a G11
thanks for any input / suggestions
