RCW85 in SHO with RGB stars

RCW 85 (The Devils Tower), is a Ha/Sii region that is in the constellation Centaurus, in between Hadar and Rigil Kentarurus. There is some very faint Oiii in the brightest part of the tower but even with 8.5 hours just on Oiii, it is well and truly drowned out by the Ha and Siii signal, even though bands do not have very strong data themselves. There really isn't a lot of signal to work with on this target. Perhaps additional data in the Ha and Siii would help a little. I found this pushed my processing skills, particularly on stretching the data. I found that GHS worked best but it still took me a couple of attempts to get to a point where I was relatively happy with the image.

Imaged from Brisbane, Australia, over 7 nights at the end of May 2023.

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.
