Getting easier to capture better SNR as the Moon wanes and time above the horizon increases, not to mention the Comet itself also brightening slowly each day.

Preprocessing:
- Darks, Flats calibration
- StarAlign
- Comet Alignment
- Batch StarXTerminator run on all Comet Aligned images
- Image Integration of starless Comet
- Comet Alignment to subtract starless Comet stacks from each set of Star Aligned shots
- Image Integration for Comet-subtracted images
- Result: R, G, B starless Comet & R, G, B comet-subtracted background stacks

Housekeeping:
- Crop
- DBE
- LFit R, B to G
- RGB Combine
- Image Solver + SPCC
- BlurXTerminator

Starless Comet Processing:
- Rista TGVD, MMT
- ArcSinH (RGB) + GHS stretch
- Curves Saturation increase
- ACDNR

Star Field Processing:
- StarX, Clone Stamp of Comet remnants, stars added back in
- SCNR
- Rista TGVD, MMT
- ArcSinH (RGB) + GHS Stretch, HT Darken
- Curves Saturation increase
- ACDNR

Combined Processing:
- PixelMath Screen Blend of Comet + Stars
- LRGB Combination using extracted L for background Chrominance NR
- Curves vibrance, contrast work
- Annotation

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.
