HFG-1 Cropped and Wide Field View in HOO

Revision title: A bit more thoughtful cropping relative to star field

The Planetary nebula HFG-1 and Abell 6 1 (PK136+05.1 and PK136+04.1, respectively) in Cassiopeia are unusual in that both are much stronger in OIII than Ha signal. HFG is named after its discovers Heckathorn-Fesen-Gull, who first described the nebula in 1982, though Abell 6 was discovered by George Abell in 1955. The striking bow shock seen in PK136+05.1 is associated with a binary star system that is rapidly moving thru the Milky Way and rotating around each other every 14 hours. The Cropped version B of HFG-1 better reveals the disjointed nature of the bow shock, and the wide field version A reveals Abell 6 and the surrounding Ha background. Credit to @Herbert_West for the inspiration to go after this target! His image was amazing.

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.
