10th Magnitude Comet C/2021 S3 PanSTARRS Closing in on Globular M9 2024-02-12

Two rigs focused on this area in Ophiuchus as Comet C/2021 S3 PanSTARRS enters the field with THREE globular clusters and patches of obscuring dust. C/2023 S3 is heading for perihelion on the 14th and not expected to brighten. The main rig, displaying this image used a RASA11 and a full frame asi 6200mcP. I'll post the "piggyback" rig using a C6 HyperStar and an APS-C sensor shortly, having co-processed this image. Imaging was made while the target was low to the south as south eastern Ophiuchus was rising. A difficult Decision to make as 12P/ Pons-Brooks was concurrently rising in the North East.

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.
