Very nice. Can you share how you did this? How many frames make up this final animation and how much data went into each of those frames? It is excellent and shows so much detail.

Hi, I captured a 1000 frame video every 50 seconds in Firecapture (+10s capture time) to give 27 stacked TIFF files (i.e. one TIFF per minute) - best 15% of frames stacked in Astrostakkert per captured video.

Align the output TIFF files from AstroStakkert in ImPPG using "Align image sequence"

Stretch "Aligned images in ImPPG using batch processing method.

Crop and Rotate plus additional sharpening in Pixinsight - Solar Toolbox.

Annotate images in IrFanView and convert to PNG files.

Create animation of PNG files using PIPP or online GIF Creator software (Makes smaller files).

Hope this helps.

Brendan.
