I've found there is always an "arms race" between what my PC can process
(in reasonable time frames) and the data my cameras throw at it.
My recent GPU based processing upgrade (for some AI based routines) has certainly helped...but a 240Mp camera would rapidly fill my hard drives and take around 16x longer per IMX455 sub to process....plus a telescope that has a perfectly flat 150mm wide field doesn't exist in amateur gear (as far as I know)
Very much a case of careful what you wish for
