About this image

Reasonable seeing conditions. Tried with and without ADC, but found no benefit from using ADC as Jupiter's altitude was high and because it was positioned between the barlow and camera meaning that the image was so magnified that the planet's disc almost filled and was quite difficult to maintain on the sensor / screen. With 5x barlow I was working at an image scale of 0.077 arc secs /px, probably slightly lower than I should have been using.

I recorded 15x3000 frame videos in RAW8 format (25s duration for each video), to save on hard disc space, then used PIP (to debayer), AutoStakkert (best 10% of frames), Astrosurface, RegiStax6 and Winjupos to process, with final adjustments with Affinity Photo.
