Comet Leonard from about a month ago, S. Hemisphere

OTA:……………….PlaneWave 17” f/6.8
Camera:………….FLI ML16803
Observatory:…. Deep Sky West, Chile

EXPOSURES:
1 each L,R,G,B: 60sec
Processed by Alex Woronow (2022) using PixInsight, Topaz

Just when you thought you were done with this thing, another image! This is from a scope in Chile, and the image shows some ripple structures in the tail, particularly the upper part. Also, some complex structures occur in and around the head.

The comet moved about ½ star disk over the period of the four images. I made separate comet-aligned and star-aligned images and then starless and stars-only images from both. After processing, the stars from the star-aligned image were re-introduced into the comet-only image to produce the final product. This approach eliminated some of the strange star artifacts that arise when using the PI 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.
