HFG-1 and Abell 6

HFG 1 is a very old large, low-surface-brightness planetary nebula in Cassiopeia. It surrounds, and was produced by, a binary star system (V664 Cas) that is moving rapidly through our Galaxy. V664 Cas is composed of a white dwarf star and a large red giant. The two stars are very close and rotate around their common centre of gravity every 14 hours.

Abell 6 is an example of a bubble-shaped planetary nebula. However, it remains quite faint at magnitude 15.

This was a great target to work on. I knew it would be a long project because I wanted a clean background and good detail within both feature targets of the image. I am happy with the shock front of HFG-1 and the "wispy" detail in the OIII channel in this object. There is a decent texture present in Abell 6 as well that was a bit of a surprise.

I added some star spikes in post production, sparingly, to add a bit more depth and vibrancy to the image.

Thanks for looking!

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.
