Last Friday night on 12/30 I was testing out my first Off Axis guider (Astrodon Mega MOAG) and imaging IC 410 - The Tadpoles in constellation Auriga and noticed a slow moving object when I stacked the images. Turned out to be Asteroid 157 Dejanira discovered in 1875. The .gif is over the course of 8 hours from 20:00 on 12/30 to 04:00 on 12/31 (EST).
First time trying to make a movie or .gif, I used Blink in PixInsight with ffmpeg arguments. Then used ffmpeg in a terminal prompt to convert the .mov to a looping gif. Sorry if this is laggy or skipping, I'm not sure how to play with the resolution or file size and quality.

Cool stuff! This hobby is so much fun!
Thanks for looking,
