Comet Leonard (C/2021 A1) from Dec 6 2021

This is an animation of Leonard created using Astroart 8's (AA8) animated blink tool. The individual frames were all colour decoded, flat fielded, hot pixel filtered and dark subtracted by AA8's preprocessing tool by using the 'keep all files open' option during the generation of a stacked image. I used the automated alignment feature to align the star field, so that the stars will remain stationary whilst the comet will appear to move. The animation was from 30 x 1min subs from the morning of Dec 12 2021. The animation was saved as an mpeg and then recoded using Handbrake.
