Comet c/2022 E3 ZTF in Camelopardalis

Like everyone else I wanted to image "The Green Comet." But with the endless cloudy skies and waxing moon, it seemed the opportunity was going to slip away. But Jan 30 was going to be clear but very cold (- 9 F) and the moon wouldn't set until about 3:30 am so this was my only chance. Setting up at 5 pm and then waiting to 3:30 am led to some very stiff cables, frost on the mount and minor frostbite on the fingers.
147 x 1 min.   200 mm Askar astrophoto lens, ZWO 294 MC pro. (sensor temp of -19C was below my dark library so I used my -10 C dark frame master) AP 1100 mount. Pixinsight: Calibrated up to StarAlignment step then stacked. Used StarXterminator to make a stars only image. Light stretch with arcsinh. ColorSaturation. Streched with HT. SCNR. Small residual part of comet clone stamped out.
Then CometAlign to correct for the comet motion of about 5.5 arc-sec/min against sidereal. Tried to integrate all the comet-aligned frames using a low sigma rejection setting but still too much star trailing artefacts so had to use StarXterminator batch star removal on 147 subs which took 14 hours on my computer.  ImageIntegration with no normalization or weighting to get master comet-only light.

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.
