Cocoon Nebula & Barnard 168, Ha

I restarted this project the other night because I rotated the camera on my Star 71 when I swapped the SX USB wheel to it from the 132, and then shot a whole new series of flats. So when I returned to this target it was either [a] start over with the new FOV/orientation or [b] rotate the camera again and shoot new flats for seven filters. Well, loath as I was to junk a few hours of data, I chose [b], and I am glad I did as I much prefer this orientation.

The Cocoon is at the lower left and Barnard 168 streams off toward the opposite corner. There are about a dozen small dark nebulae scattered around the main one [B 168] that won't show up too well in Ha, but may appear as I add other data. This is only the Ha portion of the project. After the 24th, Luna will be out of the sky when this target is available and I will collect RGB data for the final product using Astrodon Gen II E-Series filters.

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.
