Barnard 3 Environs, HaRGB (Stephen Garretson)

Barnard 3 Environs, HaRGB

This is my very first attempt at RGB. Needs lots of work, and probably lots more data, but I am reasonably satisfied with it as a maiden voyage. I combined RGB masters with Ha as an Alpha channel using PixelMath in PixInsight.

Target is generally the IREC 231 Dark Nebula in Perseus, but there are several small DNs included...BDN 160-19, LDN 1472, LDN 468; also shown is the star Atik [brightest], and IC 348 [open cluster right by Atik], to name the major ones. I think what would be in order here is simply more data.

I have been advised by many that RGB is tough from LP areas. However I also have come across imagers who have SQM reading very close to what I see at the Beevo Dome, and use this particular set of Astrodon filters with good success, so I decided to give it a whirl. I believe there's potential here. It's my goal for this to open up paths to planetary nebulae, and especially dark nebulae such as the represented in the attached image. These targets will be sought when Luna is on vacation.

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.
