Well, visually it's not that good because SCTs are a bit fussy by definition because of the sensitivity to ambient temperature variations and the big central obstruction. Mine is a three year old average C8, but with three vent holes with fans (that I never use) behind the primary and small vent holes around the corrector plate, Intes Micro style. I also wrap it up with a thermal insulation sheet during avi aquisition to avoid convection currents inside the tube. The truth is I got lucky and caught the exceptional seeing we had the night I took the pictures.
