Quoting from the description: "Exposure: 300 x 100000" ISO/Gain: 73" – well, the exposure for Mars can't be longer than the night, and it rotates... :) Those three zeros are clearly extra.

Next to each camera video, there is a description. And that's how it's written there.

Most likely, as I recall, it was around 100 seconds. I don't know why it's written like that in the description.

Actually, planetary photography doesn't use exposures measured in seconds; they are much shorter. Most likely, 100 seconds is the length of the video. So what does 300 mean then? Do you process your planetary videos yourself?

I set the exposure at exactly 100 seconds, gain 73. And it's stacked from 300 frames.

Let me point out that with such a focal length, Mars would be completely smeared into a blur over a 100-second exposure. Especially since you initially mentioned a video and stacking 300 frames. That would amount to more than 8 hours of shooting. I would readily believe it if you were talking about a 100-second video at a certain frame rate, from which 300 frames were selected and stacked.
