Thank you everyone for your opinions.
I don't see myself getting big into astrophotography because this telescope purchase in the next 12 months will almost certainly be the last telescope I ever purchase. I don't see myself every spending anywhere near the same amount of money again on astrophotography equipment. Maybe I might purchase a CCD imaging device as I already have a laptop.
So why am I asking these questions? I guess I just doing some advanced research. Just in case taking a few images takes my fancy. But I certainly don't see myself in the financial position in the future to dive into astrophotography. I am leaning towards a C11 S-GT XLT (EQ mount). And I don't want to spend this sort of money and find the telescope is absolutely 100% non-suitable for astrophotography, 2 or 3 years down the track.
montewilson: You mention the term "prime focus". Is that when you mount the CCD device to the eyepiece on the OTA?
rumplesriot: Is the flexing of the fork that much of an issue? I'm not doubting you, just surprised. Can anyone else elaborate on the drawbacks of fork over GEM for astrophotography? Is it due to the mechanics of the drive motion on an Alt/Azimuth trying to act like an EQ motion? I guess a drive tracking an object on an Alt/Azimuth from horizon to meridian, then to horizon again is a series for "steps" for both Alt and Azimuth drive mechanism? (up, left, up, left, up, left....then after the object reaches the meridian, down, left, down, left......) Correct?
