I am getting one as well. File sizes unbinned at 122mb. So if you take shorter exposures than you would with CCD, say 5 minutes instead of 10 minutes, then say 6 hours of total exposure is going to be 87gb. Plus darks, plus flats, plus flat darks and you are looking at something like 100gb for one complete image plus saved processing versions.

I would imagine ideally you need a large SSD for processing and saving temporarily and then transfer all the data to a large HDD. SSD's are faster.

Lots of RAM is always good.

If you are using a longer focal length scope you probably will be running the camera 2x2 binned. Now the files are a lot smaller.

So a large SSD, lots of RAM, i7 processor and a large HDD (cold be an external drive.

Greg.
