Having had that feeling that it could clear up in the west I quickly loaded my car and drove out, set up and used that quick gap between the clouds.
With the Moon in the east or back I shot opposite direction for that little while.

Thanks for watching!

Title: From scratch...

Description: Removed the two worst subs due to inrolling clouds. Cleaner background, more structure in the tail, improved stars.

Title: Rotating Core?

Description: Zoomed in on a sub with the worst HFR value, actually the last one that I took on that session when clouds were rolling in. Not impressive at all but when zooming in on the core and inverting that image, it seems to me that it is a rotating one...Same thought I had when looking at images of that comet with lots of tail in it looking a bit like a vortex/turbulence wake...

Title: Rotating Core - A HDRMultiscale Transform View

Description: A HDRMultiscale Transform applied to the CometOnly Image reveals a firewheel effect.
Stemming from the rotational nature of that comet?

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
