The Cygnus Veil in Hα/Oiii+RGB (2-panel Mosaic) (Brent Newton)

The Cygnus Veil in Hα/Oiii+RGB (2-panel Mosaic)

Link: https://www.astronewton.com/veil-2019

Note this is a 2-panel mosaic, so about 27.5 hours per panel, or a combined 16 hours of Luminance (Hα/Oiii) each per panel.

I'm a year late on this data set and it is definitely not the only one given how slow I am at processing my data. I started this project in July of 2019 and just never got around to finishing it until now. This is a 2-panel mosaic of the Veil using Hα/Oiii-boosted RGB, though given the boost given by the Oiii channel to the B channel it could be considered a bicolor with RGB stars.

2022 Reprocess: took more time with color and with more experience (and better software tools) was able to isolate a lot more contrast than in 2019

Pre-Processing & Mosaicing:
- Darks, Flats Calibration, Cosmic Correction
- Subframe Selector Weights, Star Align, Local Normilization
- Drizzle Integration
- Gradient Merge Mosaic following Rough Alignment using StarAlign

Housekeeping:
- Crop
- DBE
- LFit R, B to G
- RGB Combine

Narrowband Processing:
- Decon on H, O
- StarNet on H, O
- Rista TGVD, MMT
- Blended starless Oiii onto Hα, forming Master Luminance image

- GHS + HT stretch
- StarNet to form Starless L copy

Color Processing:
- PCC
- Rista TGVD, MMT
- Isolation and combination of starless narrowband images
- PixelMath to form HOO, H/H+O/O images using starless data

- GHS + HT stretches
- LRGB Combination on all color images
- Final NR with ACDNR, MMT
- 50% downsize
- Unsharp Mask
- Color tweaks
- Contrast tweaks
- Annotation

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.
