I took Jupiter and Saturn between 2-3am on morn Wed 22/5. Edge HD SCT 9.25”. ZWO ASI290MM mini with RGB filter. Sharp cap. 2min runs (600 frames per) alternating RGB filters. 3 rounds. Approx 5fps. Gain 140 for memory. Williams Bahtinov mask for focus on nearby star. Histogram 70%. 1st real time for having ironed out the bugs. Autostaker, then Registax and then Winjupos. Seeing could have been better, however beautiful clear night hear on the Sunshine Coast in Qld, Australia that night. Also, fortunately at Latitude 23S, Jupiter and Saturn were directy overhead at that time of morning. I am no expert in planetary photography but the frame rate was ~70fps and gain 390 . I understand a high gain given you a higher frame rate but doesn’t it come at the cost of more grainy image?
