NGC6520 The Dead Man's Chest Cluster with Barnard 86 in RGB with a LOT More Data

NGC 6520 is an open cluster in the constellation Sagittarius, superimposed upon the Large Sagittarius Star Cloud.

It is magnitude 9.0, a diameter of 5 arc minutes and has about 25 stars of magnitude 9 to 12. The dark nebula Barnard 86 lies near its western edge.

Under good conditions at the eyepiece it can be an amazing sea of milk, punctuated by bright stars, and the adjacent inky black B86 creates a fascinating view at the eyepiece. B86 is one of the coldest regions that we know of in our galaxy.

What a difference another lucky clear night makes, with a new moon and no neighbours lights. I should buy a lottery ticket but I probably used all my luck up.

Ruthless sub-frame rejection left me with 58 exposures and vastly better colour with very little processing required. There are simply too many stars to dive into anything too pushy so I just use Normalised Scale Gradient, Drizzle Integration, Linear Fit , and stretching with Globalised Hyperbolic Stretch, which has be be one of the best tools ever in Pixinsight. Simply amazing once you get the hang of it and makes so may other processes redundant. , Very little to do after that which is a pleasant change. Not like playing paint ball with narrow band at all :-).

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.
