Comet + Mars + 3 additional nights of data to help bring out the background molecular clouds. Rejection of Mars to isolate the star field proved more challenging than I expected - despite it being in 4 different spots during each night the basic pixel rejection of ~120 total exposures in each channel still left a few remnants.

PreProcessing:
- Darks, Flats, Flat Darks calibration
- Subframe Selector Weights
- Star Align, Comet Align, Comet Align (Mars)
- Batch StarX onto Comet Aligned Comet, Mars images (Mars masked out since StarX would target it)
- Evenly split exposures of each channel into 4 groups, stacked those, then stacked the 4 results along with a normal Image Integration (this seemed to provide better pixel rejection)

Housekeeping:
- Crop
- DBE
- Channel Combine RGB

Comet Processing:
- ColorCalib
- RistaTGVD, MMT
- CloneStamp of remaining star trails
- Masked SCNR

- ArcSinH, HT
- ACDNR
- Curves Contrast, Color tweaks

Mars Processing:
- SCNR
- ArcSinH
- Convolution, HT

Starfield Processing:
- ImageSolve + SPCC
- BlurrX
- StarX
- CloneStamp of remaining Mars, Comet artifacts
- Rista TGVD, MMT

- ArcSinH + Masked Stretch + Histogram Transformation
- ArcSinH + HT on stars
- MMT
- SCNR
- Color, Contrast Tweaks
- Bill's Star Reduction
- Screen blend Mars
- Screen blend Comet
- Final Color, Contrast tweaks
- 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.
