HFG 1 and Abell 6

HFG1 and Abell 6 planetary nebulae captured over 3 weeks in October, faint objects so needed a lot of data. Processed using PixInsight with Normalise Scale Gradient process and a HOO PIP rendering.

HFG1 is a 10,000 year-old faint planetary nebula discovered in 1982 by Heckathorn, Fesen and Gull. It was created by the collapse of a star in a binary pair leaving a white dwarf and a star similar in size to our own sun. These stars are very close to each other (just a few million km), orbiting each other every 14 hours. This binary pair are moving very rapidly through space, compressing interstellar medium to produce the pronounced blue bow shock wave above it.

To its left is the almost perfectly spherical planetary nebula Abell 6. This was also formed by a collapsing star blowing off its outer layers, collapsing to an intense white dwarf star which then ionises the expanding ejected gases with its intense UV radiation.

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.
