NGC7293 Helix Nebula

This is a 40h HaLRGB Image of the Helix Nebula, NGC 7293. From NASA APOD 2007: "A mere seven hundred light years from Earth, in the constellation Aquarius, a sun-like star is dying. Its last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution. .... The Helix's brighter inner region is about 3 light-years across, but ... the fainter outer halo features give the nebula a span of well over six light-years. The white dot at the Helix's center is this Planetary Nebula's hot, central star.

The 39.6 hours of data for HaLRGB is from DeepSkyWest (DSW) Chile collected 16 July 2021 to 19 August 2021. North is up in this image. Processed by PixInsight 1.8.8-9, PS CS6 and a light application of Denoise AI.

10/18/21: Added OIII: 14x1800s (7.0h) and S2: 16x1800s (8.0h) to the original 39.6h HaLRGB with OIII as teal and S2 as red to try to preserve the "natural" color.
Total Exposure is now of 54.5h.

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.
