Sh2-64 RGB-Halpha

Sh2-64. A revisit of old data from a few years back and a complete reprocessing.

Overlaying a rich star field is a large molecular cloud. This cloud is both reflecting light and absorbing. This cloud is partially obscuring several bright stars in the foreground the brightest is magnitude V 5.49 and a KOIII type just a tad bluer than our Sun. There is a significant amount of very dim Hydrogen Alpha emission in the area seen as a slight reddening in some areas.

Almost obscured is Sharpless Sh2 64 above center and slightly right below the bright 5th magnitude star HIP 90642. Sh2 64 is just peeking out of the cloud, which I think is a very nice effect. Near the bottom and nearly centered are LDN563 with LDN557 combine into what looks like a shark.

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.
