Lo Barnechea, Chile

Bortle 7 skies, seeing 4/5, transparency 3/5

Steven O'Meara included NGC6520, the open cluster right to the left of the ink spot dark nebulae ias object 88 in the hidden treasures catalog. In this case, B86 is hidden behind so many gems in Sagittarius and usually goes unnoticed but according to my interpretation of O'Meara, it would rather be B86 eclipsing the beauty of the open cluster. Interesting way to see it.

This is a starry and contrasty field towards the core of our galaxy. B86 and NGC6520 are easy to find with binoculars under fairly dark skies.

I had problems with the meridian flip and guiding, so lost the OIII subexposures. I ended up combining CLS/Ha and averaging both for the green channel to provide natural color.

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.
