Comet 13P/Olbers Shows Complex Twists July 07, 2024 (C14 + asi2600mcP) A fifty- fifty moment where comet Olbers show a recent outburst of tangle jets close to the nucleus whereas further away there is a more casual appearance of the plasma tail(best seen in the RASAll + Full frame post). The dust fan tail appears to be broadening and brightening.

I did a no-no by stacking 42 minutes of comet data. However when comparing the detail of the 30 and 20 minute exposures I noticed I was loosing detail. How is this possible? I believe the present dynamic activity of the nucleus is producing a large amount of jets in multiple directions. Shorter frames don't capture the whole host of activity. (just my guess).
