Another recast of a Sharpless2 object with General Hyperbolic Stretch and the CMOS camera.

Not the most exciting Sharpless2 object, but needed to upgrade my collection from the previous effort:

Sh2 87 H-alpha RGB

GHS Forum Discussion

From GalaxyMap:

Avedisova assigns this nebula to star formation region SFR 60.92-0.13 along with three masers and three molecular clouds, and says it is ionised by two B0.5 V class stars: BD +24 3880 and HD 338936.

This is a massive star formation associated with a 7000 solar mass molecular cloud and many sources in the far infrared.

The Spitzer infrared data is analysed in a 2008 paper which finds that the region consists of three distinct clumps.

GENERAL NOTE ON SHARPLESS2 OBJECTS>>>>>>>>>>>>>

There are 313 Sh2 objects. All now imaged.

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.
