NGC 7293

I rarely do planetary nebula, because I don't have the focal length and resolution with my ED80. However, the CDK-14 at SRO is more than capable with Linda Thomas-Fowler and Chris Kagy behind the wheel. This was collected over September and October. NGC-7293, the Helix Nebula, aka the Eye of Sauron, is a planetary nebula in Aquarius, the first planetary nebula found to contain 'cometary knots' which can very nearly be viewed in this particular image or maybe it is my pareidolia acting up. I am crediting Tim Triche as our wise and generous research group leader (PI). This was processed primarily in Astropixel Processor, with some cosmetic enhancements from Pixinsight and Lightroom. The images were cosmetized and stacked in PI, then the RGB combination was done in APP using the RGBSHO palette carefully weighting the Green, Blue, O3 and S2 to avoid an overwhelming fuchsia tone. The image was background corrected and the star colors were calibrated in APP. Noise reduction and stretching were completed in Pixinsight, followed by final cosmetic touches in Adobe Lightroom.

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.
