A tracked midfield image from a recent trip to a Bortle 2 site.

PixInsight Processing:

- Darks calibration in PixInsight

- Star Align and Image integration

- Luminance Extracted for separate processing

Luminance Processing

- Deconvolution with deringing using PSF Script, StarMask for support, and non-linear Luminance Mask

- TGVD for high frequency noise reduction using inverted Lum mask

- Masked Stretch

- Dark Structure Enhance 40%

- ACDNR for NR

Color Processing:

- Linear Fit to G channel, recombined

- Photometric Color Calibration

- SCNR Green 80%

- TGVD for Chrominance NR

- Masked Stretch

- ACDNR for Chrominance NR

- Curves for Saturation enhancement

LRGB Processing:

- LRGB Combine

- Morph Transformation for Star Reduction

- ACDNR for Chrominance NR (larger scale)

- Curves edits using Luminance or Star Masks for selective saturation and color balance

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.
