I agree, love my 20Da, but now thinking more and more of a self guiding SBIG which would reduce the load on my G11 if I can remove the guidescope, AND get better images....
only questions now are when, and what to get....
I am giving myself lots of time to think about it
until then i'm still going to keep on working on my skills

Thanks Humayun and Kenny.
The C14 with its WO ZS80mm guidescope is quite possibly just at the limits of what the G11 should have on it for imaging (ok most would say its way past the limit...)
I cant recall exactly off hand the total counterweights but its about 50 Lbs, i'm using a Losmandy counterweight and dumbell plates of various sizes (see my webpage).
someday i will be able to remove the extra weight of the guidescope and camera when I upgrade to a cooled self-tracking CCD but for now...i have to save pennies.
As for what to buy? I'd look for a second hand ST9XME / ST10XME, these chips are slightly smaller than that of the DSLR, so less field of view, but also shouldnt vignette at all which is a plus... they are both mono, self guided SBIG's and are fairly reasonably priced (2nd hand from USA) when to buy? wait for the exchange rate to come back a bit...
If you're not keen on mono, the ST2000XCM/ST4000XCM is for you, again, smaller chip than the DSLR, ST2K is 2mp, ST4k is 4mp. Both are self guided, great chips with moderately high QE for a color camera....
Thats enough babble from me (I've been looking at the SBIG site a lot recently, as im in the same position, with C11 + WO66 on EQ6, Im really needing to shed some weight from the system... ST10XME + AO8 + CFW is on my "to buy" list...)
Awesome colors and contrast.
