Pixinsight RGB Process

Blink for each channel to find glaringly bad frames

Subframe Selector to weed out high eccentricity and high FWHM frames

BPP for each channel

Star Alignment with red channel as reference

Dynamic Crop on each image to remove stacking artifacts and coma in the corners

Linear Fit with Red as reference

DBE on each registered image

Channel Combination

Background Neutralization

Photometric Color Calibration

TGV Denoise and MMT for noise reduction following Jon Rista technique

Pixinsight Lum Process

Created synthetic Lum from RGB channels

Star alignment to register Lum to RGB

Linear Fit with RGB with Lum as reference

Dynamic Crop based on RGB crop

DBE to remove gradients

Deconvolution to sharpen

TGV Denoise and MMT for noise reduction following Jon Rista technique

Stretch using Histogram Transform

LRGB Combination with saturation slider moved to 25

ACDNR with strong mask to remove “black tail” on left side of histogram

range_mask+star_mask created to protect background from Color Saturation

HDRMT to bring out more detail

Small Morphological Transform to reduce star size

Curves for small overalls saturation boost

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.
