Hi Eric. The secondary support on the GSO is just adequate with the fairly heavy secondary. FWIW, the plastic secondary holder on mine was flexing, so I made up a much stiffer one using plastic water pipe fittings and it helped a lot - there is still some collimation drift as other parts move, but not as much. regards Ray
