Sh2_261 - Lowers Nebula in SHO/RGB

Revision title: Side project: further processing updates on Lower's nebula.

The first major project with the new WO FLT 132. This time I captured the RGB channels plus a set of narrow band images. This image was color wise a challenge, the RGB stars came out nicely, gave the nebula on top a nicer reddish touch. The overall color though comes mainly from the narrow band channels, and the adjustment from "pure" SHO to a more pleasant "Hubble-Like" image was very sensitive. Took me at least 10 tries to get the color I was ok with. This image was also taken with the multi star guiding of PHD, and it really makes a difference, at least for me, was great to see the perfectly round stars. I might actually go for some more OIII and SII and reprocess it again, let's see if the weather let's me.

Description: In the heart of Lower's Nebula. This is actually not just a crop. I combined an PLRGB image with the SHO/RGB image and did some more detailed processing.

Description: Rework of one of my favorite nebulas. Yes indeed, seems strange, but this one is for some reason a challenge and one can make it very beautiful. Still not my final version, but it at least comes closer to it.

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.
