A planetary with a bow shock - Heckathorn-Fesen-Gull 1

Link: https://www.starscapeimaging.com/HFG1/HFG1.html

A curious planetary nebula with a bow shock. The attached image is my interpretation of a widely imaged planetary nebula called Heckathorn-Fesen-Gull 1 (HFG1) named after those who discovered it in 1982. HFG 1 is in Cassiopeia and is a very faint planetary nebula associated with the star V664 Cass, which is a mag 14.5 binary star, and is moving quickly through the Milky Way. The nebula displays a blue/green curved bow shock front as the star moves quickly through the interstellar medium and also a red tail of hydrogen.

The image was taken from August through October of this year from my backyard observatory through RGB Ha and OIII filters. Its comprised of 42hrs of exposure time. Hydrogen (Ha) mainly shows up as red within the image and Doubly ionized oxygen (OIII) is the blue/green teal color. Also within the image on the lower left is the smaller planetary nebula Abell 6. This little guy is 3 arc minutes in diameter and is beautiful unto itself.

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.
