Thanks everyone.
Roger, Mars and Saturn imaged at 12,500mm according to Firecapture, I used the 5xPowermate at about 95-100mm extension from PM top to sensor giving 7.9x which is the maximum power.
I use a 350mm Newtonian so Mars is very bright with RGB gain at 2000/3300,2600/3300,3200/3300. FPS 55,53,53. (100sec per channel)
Saturn I use full gain 3300. RGB FPS 18,12,8. (80sec per channel probably too long 60 sec is better).
Regards, John.
