Comet Ken - C/2022 E3 (ZTF) with RASA 11

Here's my attempt at this comet with the RASA 11, which obviously has the advantage of collecting a lot of data quickly.

First time I've fully processed a comet image. I used Pixinsight CometAlign process, but also Adam Block's suggestion of first removing stars from every star-aligned frame using StarXterminator. This proved to be time consuming but worth it in terms of reducing artifacts in the Comet only image. But then I still had to fiddle around quite a bit to remove these artifacts - in the end resorting to a technique shown by AstroEdy on YouTube, that involved using ABE and PixelMath to remove star artifacts while using a mask to protect the comet. This probably made the StarXterminator business redundant. Anyway, think that was all worth it!

My father-in-law Ken died earlier in the week on 17th January. As the comet has no name, we've named it Comet Ken in his honour! Kenneth Frank Loates, 1934 - 2023

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.
