Comet C/2022 E3 (ZTF)

This image was taken early morning on 16 January 2023 with a German equatorial tracking mount tracking at the sidereal rate. I reprocessed the stack of images on 23 January using the new PixInsight Comet Alignment process to create a version of the original frames that were aligned with the comet as opposed to the stars. If memory serves correctly, the new Comet Alignment process is different in that, among other features, it allows you to subtract the integrated star field (created from the star-aligned integration) from each of the individual sub frames before they are converted into comet aligned frames by the process. This does a pretty good job of removing star trails from the integrated comet-aligned image and then allows you to add back the original integrated starfield with fewer star streaks in the final product. Some use of the CloneStamp was still required in my opinion because some star streaks were still visible in the comet-aligned image, but the residuals were less than if you had used the older version of the CometAlignment process and not subtracted the starfield from each of the original frames - in my experience. Picking which starfield image to use as the 'Operand' in the new process is important. I used StarXterminator on the integrated stars-aligned image to create a starfield with no comet. I used this comet-less starfield in linear form (after applying dynamic background extraction) as my 'Operand' in the new PixInsight Comet Alignment process.

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.
