NGC 6729 R Coronae Australis Complex in HaLRGB

In an effort to further practice some LRGB processing, and to fill in a few gaps in imaging time while waiting for various targets to rise, I started imaging this beautiful region of space. After having some early success with what I was seeing come through, I made a plan to go for 16 hours of LRGB (4hrs/filter) and my usual set for RGB stars, just to be safe.

Part way through this, and very much on a whim, I decided to see what kind of Ha response was in this region. To my surprise even single 120s frames had a reasonable Ha signal right in the very bright area, so i decided to throw in 4 hours of Ha while i was at it. Interestingly enough, there is a very small amount of Ha signal present in the dust clouds, and the pressure wave from that big bright star on the mid-right of frame is pretty clearly defined in the Ha. Given the shape, and the amount of blue response around that star, I may look at seeing what kind of OIII signal is there as well.

As with all my images of late, They're being processed on a Gaming laptop, which has a pretty poorly calibrated screen, so while the colours look pretty good to me, I'm very much open to critique.

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.
