Usually a pause in a sequence is manually instigated due to clouds, a certain parameter is incorrect, focus is off or perhaps the image has drifted due to dithering etc. Perhaps some more options might be available when hitting pause? This could include something like “re-focus and continue with the sequence”, “re-plate solve and continue with the sequence”, or “move to next calibration frame and return to paused state”. The flexibility of moving to a calibration frame on pause allows some hands on control (like switching off the auto pilot) and means a flat box can be added for flats or the scope covered for darks. A return to the pause state would be good to both remove the flat box (or cover) and to assess if the clouds have cleared and the sequence can be resumed.
It moves away from automation but recognizes that pausing is a deliberate intervention in the sequence.
