This is the "Red" channel, it is captured in R,G,B with thousands of frames each, which are then aligned, stacked, and integrated to form the image you see here. The fine details are resolved through a process called "lucky imaging" where only the sharpest parts of the video are saved and used for a stack. That is how I'm able to see Valles Marineris (the USA-sized canyon on the right of the image) even though it's a blurry mess in the video.
I will be adding the RAW data from this shot so any aspiring astrophotopher patrons can take a crack at processing this themselves!

Its actually not as much as you'd think! I think it was around 2GB, since the image was only 200x200 pixels. It's much higher when I do my lunar/solar work

Wait that one shot is 100,000 frames. How many GBs of data is that? At the resolution Very spiffy vid Andrew 😁
Within 3 minutes. After that, the planet's rotations causes details to become obscured. I usually aim for around 100k frames, give or take.
Are the frames captured over a period of time?
