Memory allocation per image

[Dunmunro]

I've just been testing AA9 at my observatory and I've noticed that each image opened seems to use about twice as much memory as the actual uncompressed colour TIF image size; AA8 does the same. Is there some way to reduce memory allocation to equal actual image size?

Each fits image opened from my ASI1071MC camera causes AA8FP6/AA9 to allocate ~200MB of memory per opened image with an additional 300MB allocated at the start of the imaging sequence.

My remotely controlled mini computers in the observatory have less RAM than my processing computers and I want to minimize memory use especially as the ZWO ASCOM driver seems to allocate a large memory buffer upon downloading an image.

ASI1071MM, Is that a new model discontinued model or mistake

Hello, it's not possible to reduce the memory used, but you may use the LAA or the 64 bit version.
If the MiniPC has an SSD it will be very fast to use virtual memory on disk, even if the physical RAM is only 2 Gb.

It should read ASI 1071MC = APSC bayer array camera.

OK, thanks.
