This is spinned off from #169.
This evening I tested in the field with the old netbook (with swapfile) and version 0ebcfa6. I stacked total 50 subs each 5 second on M42. All are stacked successfully and the netbook survive without hanging or crash. So this is a success.
Nevertheless the speed is extremely slow, the cycle time to stack 1 frame is about 55s. So a 5s sub take 55s to process. The image is 2028x1520 in size. This is impractical. Certainly not a fault of ALS. Currently I am running ASTAP in this netbook and the cycle time is about 15s. The quality of the stack and stretched image is much better coming out from ALS, so the comparison is not a straightly fair one.
It appears that the bottleneck is in "stack" as the queue is there. Anyhow I still would like to explore possibilities in speeding up. The question is: If I disable the level and RGB process (uncheck the box), leaving only the stretch box checked, will this speed up the process? For EAA, color balance is not that much of a concern.
Another observation in the field is that I have no way to zoom in/out the image. The doc says use the mouse wheel. But on the netbook or laptop etc there is no mouse wheel. Could we add some key strokes to enable zoom in/out (eg. PgUp/PgDn or arrows).
