Hi,
You dont need to shoot for so many minutes. Usually a few thousand frames should suffice. When you stack you throw away around 70% anyway. Planets are so bright that a few thousand good stacked frames is all you need. A zwo asi 290 easily gets 30 fps without dropped frames on a good laptop and thats only a few minutes. If you have usb 3 and restrict to a region of interest, the area around the planet you can easily get over 100 fps. Any field rotation is automatically removed by registax anyway.
So you could take multiple 2 minute videos, process and pick the best.
And No, you dont need an eq mount for planetary imaging.
Cheers
