Yep, Still Here...Comet C/2021 O3 PanSTARRS...Faint, However Survived Perihelion

With its Perihelion passage on April 21 of this year and a periapsis of 0.24 AU Comet C/2021 O3 was certainly going to be roasted by the sun. With the possibility of naked eye brightness in the early parts of May as it emerged from evening twilight I set out on four different evenings in hopes of capturing the possible splendor. Armed with a RASA8, an asi2600mcp piggybacking a Rokinon 135mm and an asi 294mcp, I shot a lot of twilight and Mercury as it visited the scene with the Pleiades. The comet was NOT there, or should I say bright enough for me to grab. Frustrating.

Turning my attention to the end of the month, May 24, after seeing others postings, I imaged over two hours of this fast mover as it moved by several "NGCs" - brighter galaxies. The individual 60second lights barely showed a hint of the comet, however once debayered, the green hue was unmistakable in contrast.

There appears to be an extremely fain tail. Can you pick it out?

Best to all,
Dan

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.
