Dear all,
Jupiter was imaged when it was about 45 degree high. The atmosphere was not stable but I just tested the equipment setting.
CZ 12.5-inch Dob with primary mirror at F5 on top of Tom O EQ Platform. Visual drift alignment was done for better polar alignment.
Taken at 10 fps; shutter speed 1/33; gain 20%; saturation 50%; gama 5%. 2x Powermate with effective F-ratio at F10.
1200 frames stacked in Registax 3.
Next time I shall try to image at F20-F25 and to add IR-cut filter when Jupiter is near the zenith.
