Nice Skies for Comet 13P/ Olbers, May30 2024 Still Only 20 Minutes

It surprises me to see how fickle the seeing can affect a comet's appearance in these images. Here on Thursday night, star sizes weren't too bad and transparency was satisfactory as comet 13P/ Olbers set in the west. The plasma tail and overall appearance showed a little more depth with the sky conditions.

Starless stacked comet aligned image included (Calibrated, aligned, star removal and stretched only)
