Comet C/2017 K2 Panstarrs and M10 cluster (NGC 6254)

This was a one off chance to capture these two together.
I only managed 44 subs of one minute each before the seeing got too bad.
I've only just got round to getting a useful result (October 2023) when compared to everyone else on Astrobin.
The processing sequence was quite convoluted and is as follows:
1. Stack groups of 5 subs so that the comet has not moved much.
2. Enhance each of the groups with simple levels and curves corrections.
3. Pass each group through Starnet++ to get starless images.
4. Subtract the starless images from the groups to get stars only images.
5. Stack the images from 4. in Deep Sky Stacker to get one enhanced image of the stars and process this a bit further.
6. Take the images from 3. above and hand align and stack to make a stacked image of the comet.
7. Process the image from 6. and enhance further with noise attenuation and sharpening.
8. Add 7. to 5. and finish off with minor adjustments.
Took me most of a day to process this but I'm now happy with it.
Hope you like it

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.
