62P/Tsuchinshan: a comet in the winter sky

This is my attempt to photograph comet 62P/Tsuchinshan. The images were taken on the night of December 27-28, 2023, when the comet was in the constellation Leo and near the "Hamburger" galaxy (NGC3628).

The individual subs have quite different quality - some had perfect visibility, but many have high clouds.

In the end I was able to take 50 images at 120s with an L-Pro filter using a modded Nikon D7200 and WO Redcat 51.

The process in PixInsight looks like this (I left out some minor details)
- Use WBPP to calibrate, align and integrate the data
- Then separate processing of comets and galaxies/stars....

Comet:
- SXT to remove the stars from the registered partial images
- CometAlign to align the comet in the starless images
- LocalNormalization
- Integrate the aligned and normalized comet data

Stars:
- SXT to remove stars from the master light produced by WBPP
- Process as usual

Blend:
- use PixInsight screening to blend comet and stars/galaxy
- process as usual

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.
