Details:
Taken with a Lunt 50THA with an upgraded Feather Touch Focuser and a Coronado 15mm blocking filter and a ZWO ASI1600 camera. This short video stack was limited to only 20 seconds because a stationary tripod was used. Processed using AutoStakkert and keeping 6% of the best frames. Image acquisition was 40 fps.
