Western Veil Nebula (Michael Vincent)

Western Veil Nebula

===Capture===
107 Ha at 300s, 200 gain 50 offset
109 O3 at 300s, 200 gain 50 offset
50 R at 15s, 200 gain 50 offset
50 G at 15s, 200 gain 50 offset
50 B at 15s, 200 gain 50 offset
Bortle 7 suburban zone

===Narrowband color processing===
Crop, DBE each channel
Linearfit Ha to O3
HOO PixelMath combination
MMT noise reduction with Lum mask
Masked stretch; select background with preview window

===Luminance processing===
O3 as luminance
PSF Image Creator - Harmut v. Bornemann
Protect background with range mask
Deconvolution, 30 iterations
7 5 3 1 wavelet layers

Fix star rings:
Starnet on original Lum
Stretch further with histogram transformation as needed to fully cover rings
Apply mask on deconvolved image to protect all but stars
Pixelmath original Lum (before deconvolution) onto image. Can do multiple times if rings remain

Noise reduction on Lum:
Copy lum, stretch, low contrast, stretch to middle of histogram
apply mask, invert to protect lights
MMT noise reduction

Masked stretch; select background with preview window

Add contrast with LocalHistogramEqualization (mask off background)

Fix stretching artifacts on 52 Cygni by PixelMathing in better stretch with GAME mask

Light noise reduction with lum mask

===LRGB===
Apply Lum to RGB with LRGBCombination
Contrast curve
Mask background with Luminance, then saturate lights
Curves with color masks

===RGB Stars===
RGBcombination of RGB filters
BackgroundNeutralization & ColorCalibration
Register to LRGB
Masked Stretch

===Final===
Starmask, delete nebula region of mask with PixelMath
Extact Lum from LRGB
Apply starmask to LRGB, apply RGB stars with PixelMath
Apply Lum back to LRGB
Strong Luminance mask, MMT noise reduction
Final crop

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.
