VDB152 The Wolf's Cave Widefield HaLRGB

Revision A- Full resolution, for those who want to load the file and pixel peep.
Revision B- Bin2 for those who want to click-drag-zoom

This was a crazy difficult target to process for me. I am very comfortable processing dusty widefields but blending Ha in is something that I struggle with. I tried a bunch of different methods (found online) to mix the Ha in, but I didnt like the result on any of them. I ended up doing trial and error with pixel math and found that applying it to Lum and RGB respectively took very different approaches.

The Ha in this area is quite faint, and doesnt show up in a single sub, even with Epsilon. Interestingly, the filaments that run through the Wolf's Cave are pretty obvious and start coming through with out too much time, but less commonly seen is that the entire field here has a diffuse Ha signal. It was a real balance to include it without making it look like gradient signal, so I wasnt too aggressive with showing it off. I really wanted the focus to be the dusty elements of the image, and just accent it with Ha. It's seen here as a subtle reddish undertone. It's clear there are really three layers of signal here. Ha is furthest out, then the broad IFN field is next with the dark nebula in front of that.

I spent more time editing than I would have liked, so I'm going to leave it here and may (or may not) touch it up at a later date with a fresh set of eyes.

Captured over the course of an Epic week of clear skies here in the Northeast USA. The Lum and RGB were captured on the days surrounding a 50% moon, while the Ha was captured closer to the full moon.

C&C Welcome.

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.
