57-frame source video
The example video is included locally and every output below is derived from all 57 frames. Median stellar registration residual: 0.512 px. Detected object velocity: +0.696, -0.304 px/frame. Persistent sensor defects: 9 hot and 132 dark pixels. The second pass selected a Gaussian sigma of 18 px from five tested candidates.
All preview boxes have the same size. Source pixels retain one common display scale, so smaller common-area videos remain smaller inside their boxes rather than being enlarged.

Download MP4Mean and median products
Each image uses every frame of its named video sequence. FITS stores three RGB planes and an NFRAMES header. The products follow the same original, star-reference and object-reference layout as the videos.
