The Veil Complex 2 Panel Mosaic

I have wanted to do a mosaic of this area for 2 years. I started it last summer as a 4-panel mosaic but the weather killed my attempts.

I decided to try and reframe this into a two-panel mosaic so I could get more data per panel and a higher SNR. I thought I had planned it so I could use the 4-panel data but found it wouldn't actually work. So I had to toss last year's Ha data. Just as well because I was going from the Orion Ha filter to the Astrodon. Thankfully I finally got my Ha filter back from Astrodon and was able to complete the project. I actually thought I had closer to a 1:1 of Ha and O3 data. That's what I get for thinking.

As usual, I have tried various processing techniques. I ended up doing a straight HOO for the color data, took it into PS and killed it with dust and scratches. This helped with the different sized stars (3nm vs 5nm) and made them look more natural which I feel gives the nebula the spotlight with higher fidelity. I pulled the greens back a bit. I did a max(Ha,O3) for the Lum. Processed that with light NR. I think the final version was stretched with Masked stretch then combined. Then the NR. Masked LHE to get a bit more contrast in the nebula and add a bit of depth/dynamic range to it.

Then RGB working space to RGB data, LRGB combine, I found I needed to do background neutralization to get some of the red and blue cast/gradients to be toned down. Then curves to adjust the color a bit more and add a bit of separation from the background. I normally then take it into PS and play with highpass but it looks to be adding more noise than improvement.

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.
