20" ... wow, it is probably going to weigh somewhere in the order of 50kgs. GSO keep on upping their RC aperture, you wonder how far they will go. i am yet to see some images from these big RCs, Paul uses the 12" and gets great results. i have been considering, for some time, the combo of the EQ8 and the RC14 but haven't pulled the trigger yet. 20" though ... we are definately experiencing a new era of amateur astronomy.
