Quick capture which turned out decent despite a large Moon being up. Star colors seem odd to me since they noticeably shift from blue-dominant to yellow-dominant across the image, and I'm not sure if this is natural due to the wide field of view featuring stars on the right being closer to the band of the Milky Way, or if my lens may have something wrong with it.

Pre-Processing:
- Darks, Flats, Bias calibration
- Debayer, CC, Weights,
- Star Align, Integration

Housekeeping:
- Crop
- DBE
- Photometric CC, Magenta Star Script

Post:
- MorphTrans to reduce star trailing (weird tracking issue)
- L extraction for sep processing
- TGVD, MMT (Rista method)
- SCNR for color image

- ArcSinH, MaskedStretch for color
- Masked Stretch, Histogram Stretch for L
- Applied HT stars t MS stretch
- ACDNR (Rista) NR for both
- Unsharp for L
- LRGB Combination

Final Processing:
- MMT using darkened ACDNR Mask to remove LS CNR
- Curves for Color tweak, Saturation, Contrast
- Dark Structure 3x3, 7 layer, 0.5 application

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.
