Barnard 72, Snake Nebula

In a larger region of other dark nebula in Ophiuchus, Barnard 72 - The Snake Nebula, stands in the foreground of a dense Milky Way star field.   The cloud is ~650 light-years distant. Given an extent of the nebula at ~ 1/2 the field radius (minimum), the nebula is estimated at no less than ~4 light-years in size.     I'll note that PixInsight counts over 25,000 stars in this field, but as with the write-up for Barnard 86, the actual number of stars in this rectangular pyramid volume (through to the far side of the Milky Way), is on the order of 200 million stars.

I used BlurXTerminator extremely cautiously on the object. The star sharpening setting was zero.   Larger would have wormed the smallest stars.   All I wanted was a very light touch to round off star elongations.

Finally, this object was not an intentional target.   Rather, it was a convenient place to capture some frames while waiting for weather to clear elsewhere in the sky.   I only grabbed an hour's worth of data.   I'll return to this object in the future for a proper amount of integration.   For now, it's a placeholder.

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.
