Wolf's Cave Nebula, Barnard 175 crowned by vdB 152

Revision title: Showing Herbig Haro object HH 450

Located in Cepheus, Barnard 175 is the relatively dim and linear Wolf's Cave Nebula, terminating on the far right with the bright blue reflection nebula vdB 152. Immediately below the reflection nebula is a small red linear HH450, a Herbig Haro object, a narrow jet of ionized gas in an area of new star formation. In the first version, I had removed thinking it was some odd artifact, only to realize later it was signal that belonged in the final image.

Title: Showing Herbig Haro object HH 450

Description: When I first processed this image, I was distracted by the small red "artifact" in the far lower right, immediately below the blue reflection nebula vdB 152. Further image reviews disclosed that this is actually HH 450, a Herbig Haro object. This version restores that object.

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.
