Hello, Roman
Welcome to Ice In Space!
In terms of chip size, with the DMK21 at 640x480 and the DMK31 at 1024x768, I suspect that Jupiter will easily fit on either chip, although you will have a lot of (wasted) black space on the larger chip.
However, on the Moon, the larger DMK31 will mean that you can image larger areas whereas with the DMK21, you will have to make mosaics which is quite time consuming.
In terms of pixel size, the DMK is 5.6um versus the DMK31 at 4.65um. I’m not sure if this would make a huge difference in terms of image quality and the ability to resolve finer detail? I suspect the effects of the seeing (Earth’s atmosphere) would dominate here?
The DMK21 60fps versus the DMK31 30fps could be important if you are imaging Jupiter through RGB filters. Then, you need to collect as many frames as possible with each filter due to the rapid rotation of Jupiter.
Cheers
Dennis
