Veil Nebula Mosaic

This is a 6 panel mosaic of the Veil in Cygnus in HOO. It is an addition to my previous 4 panel image. This is probably my favorite image to date with the 8" F4 Newt and 268m.

Processing (From what i can remember

)

Plate solve each panel
Mosaic by coordinates on each panel & Trim Mosaic Tile
Photometric Mosaic in groups of 2 (Panel 1&2, Panel 3&4, Panel 5&6)
Photometric Mosaic on the groups of panels
Cropped out black areas outside of panels

Multiscale Gradient Removal on the Oiii data using my Rokinon 135/ASI294mm Oiii data following https://www.nightphotons.com/guides/multiscale-gradient-removal
Starnet 2 on clones of the Ha and Oiii
Pixel Math to get star_mask's for each channel
Dynamic PSF on the original Ha and Oiii with stars
Starless decon on Ha and Oiii
Stretched starless Ha and Oiii
Stretched star_masks of each channel to taste
Combined Starless and Stars using @Charles Hagen relineraization technique found here https://www.nightphotons.com/guides/star-addition
NoiseXterminator on each channel(.35 Noise Reduction 0.0 detail)
HOO Combination
Starnet 2 to pull out non-linear stars, SCNR 100% Green, invert SCNR 50% Green on the starmask, stars added back in
Background neutralization
Multiple Iterations of curves
Additional background Neutralization
Multiscale Median Transform with inverted luminance mask targeting chrominance
Integer Resample 2x

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.
