NGC7293 - The Helix Nebula

The Helix nebula lies roughly 655 light years away in the constellation Aquarius. It is a planetary nebula, which is a type of nebula that forms when an average intermediate to low-mas star reaches the end of its life. As the star runs out of fuel, it sheds its outer layers. The central star remains energetic and the radiation it emits causes the previously expelled gasses to fluoresce. Eventually, the central star becomes a white dwarf. Our own Sun will someday meet a similar fate.

This data was collected over many nights over the past couple of months. Conditions in Chile have been brutal this winter. Rather than let the scope sit idle, I allowed the data to accumulate in conditions that usually featured very poor seeing and/or thin clouds. I ended up using about 30 hours of data, but the average quality was still pretty poor.

The resulting image is not as nice as I would like. But it represents a lot of scope and processing time, so I figured I would post it any way. I will definitely be adding a lot more quality data to this project soon, especially in Ha to better resolve the outer shells.

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.
