Equipment: Celestron AVX mount, Celestron C8, Celestron R, G, B filters, manual filter wheel, JMI Motofocuser, Skyris 236M, Masuyama 1.5X Barlow.
Software: SharpCap, BiggSky, GIMP.
Capture: Sets of 2000, 3000, 5000 frames with 640x480 capture area. Centre or Lock used to hold ROI steady. Exposure for each filter adjusted to put histogram at ~75% saturation.
Processing: Stack + Denoise (100/100), Decon. Combine RGB sets (R used for alignment), create Luminance (from RGB) for LRGB. GIMP for UnSharpMask. BiggSky was only stacking ~30% of frames, I regularly see 70-90% of frames stacked - a good indicator of the conditions.
For R filter: SER, MONO8, 640x480, gain 408/480, exposure 12ms, 5000 frames @ 82 fps.

10 years ago using a newly purchased Nexstar 6SE and 2Mp Solar System Imager I managed this image. It took me 3 nights to get the planet on the camera sensor!
