ASIAIR based workflow

Using ASIAIR Live Stacking Mode

updated: 2023-07-03

Live stacking needs some preparation - in order to work correctly you should first shoot calibration frames like bias, dark and flat frames with the live tracking function. Different from the Autorun and Session Plans, the calibration frames are stacked during the shooting process to so called Master Calibration Frames  for later stacking together with the light frames.

Stop Live Stacking

Important: there is no other way to limit the number of exposures than to manually stop capturing frames. 

Save the Stacked Image

Don't forget to save the stacked image by tapping on the symbol. The stacked image file name starts with "Stack...", see example above.
