PixInsight Processing:
Weighted batch processed
Dynamic crop to remove stacking artifacts
Screen transfer function to find background for extraction
Dynamic background extraction
- left default points but adjusted threshold where needed
Create masks blur at 3
- cyan
- magenta
- green
Mask magenta
Curves transformation
- pull down lower limits of red down
- desaturate
Mask green
curves transformation (goal is to get greens to yellow gold)
- middle of green down
- middle of red up
- middle of blue down
- rgb brighten
- reapply previous transforms again
- CIE up on high end
Mask cyan
curves transformation
- middle of blue up
- middle of green down
- if pink pull red down
- RGB brighten
- CIEB down
- saturation up
- reapply above
- red down
- RGB brighten
- lightness up when oversaturated
- CIEB down
Remove masks
Curves transformation
- brighten / darken
- increase saturation
- increase CIEC
- almost cartoonish
Red mask
- take red down
Noise Reduction
- clone H master
- histogram stretch
- increase contrast
- add as mask to H layer
- multiscale linear transform - noise reduction
- histogram stretch
- apply as inverted mask
Copy of sho
- convolution - blur
LRGB combination with Contrasted L Mash of HA
- Curves transformations
Local Histogram Equalization
Apply Star Mask
Morphalogical Transformation

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.
