AA5 crash in processing large number of files

[Forum_2017]

Trying to process 600 color raw files (taken with ASI174MC Cool).
First time I succeeded while used average stacking method.
And succeeded stacking 150 with sigma.
But larger (300 median) all crashing.
Have 16GB memory.

Hello, install the Service Pack 5 for AA5 and use only the LAA version. Be sure that the Astroart desktop is empty before launching a critical stacking.
BTW median is usually bad as S/N, much better Sigma or Average+Hot pixel correction.
