NGC 6726 / NGC 6727 = Reflection Nebulae + NGC 6723 = Globular Cluster + Corona Australis

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

This image of the northern boundary of the constellation Corona Australis, or the Southern Crown, shows the bluish reflection nebulae NGC6726 and NGC6727 near the centre, with huge dust clouds spanning a rich field of stars.

Above and to the left of the nebulae is the magnificent globular cluster NGC 6723. Although NGC 6723 appears to be part of the Corona Australis group, its ancient stars are 30,000 light-years beyond the young stars of the Corona Australis dust clouds.

The smaller yellowish, fan-shaped reflection nebula NGC 6729, also known as Caldwell 68, surrounds and extends out from the young variable star R Corona Australis (RCa, nearer to the top left in this image) toward its companion T Corona Australis (TCa, nearer to the bottom right in this image).

Toward the right lies the bluish reflection nebula IC 4812.

Also visible are gam-CrA and eps-CrA, two of the stars forming the Corona Australis constellation.

The boomerang-shaped dusty dark nebula known as Be157, or the Corona Australis Molecular Cloud, blocks light from more distant background stars in the Milky Way, and is one of the closest star-forming regions to Earth at about 430 LY away.

Description: I edited the original image to restore colour balance - in the previous image the colour of the stars was bleached out.

I was amazed to be able to see the dust and gas in the star-forming region of the emission/reflection nebula NGC-6729.

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.
