I don't know of any cameras that work with just a tablet (but I don't really follow the tablet side). I think you are limited by drivers to just Windows and Linux. There are a few options that use a Raspberry Pi (or one in a proprietary box) to control the camera and capture the images and then you control that from a tablet. Most of the newer CMOS cameras are lighter than a camera with a similar sensor size. You will have to factor in a power supply for cooling. Typical draw would average around 1A.

I'm thinking specifically of the QHY 367C and running it via SharpCap on a Surface Pro 6 tablet ... check it out at QHY 367C.

Well that is a very nice little device! Basically, it's a Sony A7R sensor, with cooling, packaged for raw access over USB3. Seems to be about $4.4K, which is really cheap for what it is. Tempting indeed....

And it doesn't use Sony's funky lossy compression scheme, writes truly raw data (so no "star eater" issues!) and also doesn't drop back to writing 12-bit files for exposures longer than 30 seconds. Plus, it has no IR filter, so I can use it for daylight IR photography, too! Not only that, but its form-factor -- no deep, built-in handgrip! -- makes it quite easy to mount it on all three of my FrankenKameras and/or swap it between them in just a few seconds.

It only does 3.2FPS at full resolution, so scanning a large area isn't going to be blazingly fast....

Although I have some concerns about using a rolling shutter, 3.2 FPS is fast enough for my purposes. I'm also concerned about how well it will perform using a B+W hot filter for daylight photography. Both of which are the main reasons I want to try one before buying one, because it won't be the bargain it otherwise appears to be if I can't get it to work well for the type of photography I do.
