My Last Images from July Shows Fading Tail; Comet C/2023 E1 (ATLAS) 2023-07-20/21

My Last Images from July Shows Fading Tail; Comet C/2023 E1 (ATLAS) 2023-07-20/21. Actually a superbly clear and tranquil night imaging C/2023 E1 (ATLAS). Due to the apparent speed picking up as this comet closes in on August 18th (Earth's MOID), I had to reduce the exposure time from 120 seconds to 90s. Even thought I reduced the time for individual subs the stacked total still exceeded 1.5 hr of integration time under near ideal sky conditions. The easily seen anti-solar tail, for individual subs from last week, has been absent over the past few nights. Also, may be a bit of a "stretch", nonscientific-ally the coma feels larger than a week ago.

A word about the comet's color... can't make this stuff up... the coma appears to me to be quite bluish vs greenish as others have pointed out. This image has been color calibrated using the procedures outlined in PixInsight's comet notes (seen here). I took the liberty to saturate the calibrated hue as issued.

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.
