Abell 39 RGO with RGB stars added

Rev A: the RGB data.

Rev B: the RGOIII image using the OIII for the blue channel.

Rev C: A and B combined to enhance the stars colour.

Rev D: A new process giving better star colour and a better background.

Rev E: Total new process adding the OIII to the Blue and Green channels. Same technique as making a HaRGB image. Then added the RGB stars back into the NBRGB image. Started out as an experiment with Pixinsight. Very pleased with the end result.

Rev F: Just a reprocess no extra data. Looks a lot cleaner.

Processed in Pixinsight. Data is a first light using SGPro.

G

Description: Reprocessed the data using PI's photometric colour balance on the RGB. Then extracted the blue and green channels from the OIII. Then used the NBRGB combination script to add the new OIII to the RGB in the NB green and blue channels, if that makes sense.
Also Julian R pointed out my flats were reversed on another image. Caused by taking the flats with Artemis and capturing the subs with SGPro. This has rectified a lot of background issues on many of my old images.
Still. I like this revision as it's enabled some small details inside the Pn and around the rim.

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.
