Preprocessing:
- WBPP calibration only using Flats, Darks, and Flat Darks
- Cosmic Correction
- Debayer
- Subframe Selector, Star Align
- Image Integration, Drizzle Integration

Mosaic Prep:
- Crop per panel
- LFit R, B to G, Channel recombine
- DBE, several passes
- DNALinearFit between panels to match intensity
- Star Align for rough mosaic assembly and panel separation
- GradientMergeMosaic

HDR 15 second preprocessing:
- Batch convert to TIFF using ACR (allowed better core color preservation)
- Cosmetic Correction, Subframe Weighing, Star Align to Mosaic image
- Image Integration
- DBE, SPCC, BlurX, HDRComposition, DNSLinearFit Script to blend into primary image

Post:
- Crop
- LinearFit R, B to G
- StarX + DBE
- ImageSolver + SPCC
- BlurX, StarX

- Stars given ArcSinH, SCNR, Curves vibrance increases, and a masked HT to brighten stars outside nebulous regions

- HDRComp to blend 15s exposures in to recover Trapezium detail
- TGVD, NoiseX, MMT using various inverted masking
- HT Clip, Masked Stretch
- Non-HDR variant given standard HT stretch
- Additional NR using NoiseX and ACDNR (Lum) and MMT (Color)
- Curves to tweak vibrance and color balance using Lum Mask
- HDRMT
- UnsharpMask
- Star Screen blend via PixelMath
- Additional downsize via Resample, Annotation Rendered

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.
