We have started to use live stacking in AstroDMx Capture to improve the preview whilst capturing individual RAW fits files of the DSO. At the moment, live stacking is a work in progress but we are already finding that the image capturing process is more pleasing as we prefer to monitor the imaging and guiding as we are capturing. The RAW fits files captured are untouched, but the stacked display steadily improves as the signal to noise ratio increases as the square root of the number of files that have been stacked.
