live stacking for EAA, please check Sharp CAP for windows app.
A slider that adjusts the brightness and color of the stacked images can be used conveniently for viewing.

You can detect if the telescope as moved with the RA and DEC FITS keyword.
But it is necessary to compare with some tolerance because the mount driver can update the coordinates after pulse guide command.
This is probably the most universal way to deal with the problem. For example many people doing EAA use the telescope handpad to move the telescope and the imaging application is not aware of that.
But the most reliable is a Start/Stop button in the stacking application, so it not stack until the user finish to center the object and sometime focus manually.
That's already available.

Old stored images were used for he live stack. Nothing else out of the normal being used except MQTT broker on Windows!
2. On my test rig ,which runs DSS Live and Astroaster ok ,I was unable,once live stacking started, to do anything within ASTAP as it kept displaying the dreaded revolving circle and "no responding". Task Manager showed very high processor usage but no more than either DSS or Astrotoaster - figure shown was around 34% with only 2.7gb out of 7gb of memory used.
3. I could not find a way to just monitor RAW (CR2 files) as per DSS etc and let ASTAP do the conversion if required to FITS. I know ASTAP will convert RAW files to FITS for normal stacking,
