I just purchased a ZWO ASI6200 mono camera. I have a MacBook Pro. I'm scared to death that I won't be able to process my subs in Pixinsight. does anyone one have any experience with these large images?
Don't worry, it will work. It will just be long.
I have a ASI6200MC and I use Pixinsight on MBP 15 2019 core i9 32Gb : it rocks. For sure it is sometimes long but no real issue.
Mono camera will take less memory & space than color camera. So, your configuration will run.
But, I want to understand something...
you have the camera...
you have the MBP...
you have Pixinsight...
You don't want to make a try ? you think you will kill your MBP if a 60Mp image jump inside ????
If you don't have yet some "astro" images, take bias or Dark and try to integrate some Masters with maybe 50 of each. You will see how long it takes to integrate.
Thanks! And yes to more whisky! I thought I was the only whisky enhanced processor.You should have no issues, I use an i5 with 16gb RAM and never had an issue...it just takes a bit longer (more time for whisky) ...

FWIW this is an area I feel like PixInsight could improve, by doing it all in memory like other competitive stacking programs. I really like some PixInsight features especially large scale rejection but CCDStack is just so much faster for the same SNR and FWHM.
PixInsight only does the final integration in memory. PixInsight requires you write all the calibrated and registered files to disk. This means its several times slower than similar programs as well as a lot of write cycles on the SSD. I have no problem keeping everything in memory. My computers are either 32GB or 64GB of RAM and use 1TB or 2TB Samsung 970 M.2 drives.?? PI does do it all in memory. ImageIntegration has explicit controls for how much ram to use when stacking. it is impossible to keep everything in memory all at once on most PCs, so either the OS's virtual memory system has to manage memory or the application does.
