I've been doing 10 min subs in rather shocking LP for quite some time now. PixInsight takes care of the LP pretty well, but I've been thinking...
Would I - given the severity of LP - be better reducing my exposure time back to 5 min subs instead? Here is an example of my current setup (FSQ-106ED plus SXVR-M26C OSC CCD) - 600 sec subs (2 hrs total), with NO filtering whatsoever with merely PI LP/gradient removal:

I know this one has been hacked out to death, but I think I may actually gain by less exposure (but same or longer total time) to the deep red menace that is my LP.
