Well, all things considered, I am happy enough with this rig for planetary work. I am in a seaside suburb so salt air and background suburban light are an irreducible problem that will always limit what I can do. Last night, I ran some images between 9 and 10 p.m. when Saturn and Jupiter were well up. Curiously, after Jupiter got to around 60 degrees elevation, the seeing suddenly went to the dogs completely. No obvious reason why. Humidity was climbing up and was probably about 80% at ground level by that stage.

Anyway, here are a couple of samples of the best I could achieve. No doubt a EdgeHD1100 or something else with great gobs of aperture would have done better, but that's just the way it is with 8inch reflectors.
