They’ve come out well there Martin, been eyeing off the QHY600
As for dealing with 60mp files, it’s not that bad. Although I haven’t played with data from this sensor I’ve long been drizzling files from the QHY163M/ASI1600 which produce 60mp images. Drizzle integrating from my Nikon D810 and ASI094 and editing 870mb files. It slows things down a bit but other than that, it’s not really that different.
The one caveat to this is during integration and having to be careful of computer crashes if you don’t pay attention to the size of your stacks

I mean, my newer desktop has 128mb of RAM but when integrating 300+ debayered 36.3MP files in PI, if you have it integrate all 4800 pixel stacks at once you’re asking for trouble
