NGC 6992 - Eastern Veil Nebula (HOO)

Link: http://astroquest1.blogspot.com/

Located 1470 LY from us in the constellation Cygnus the Veil Nebula is a cloud of heated and ionized gas and dust. NGC 6992 or the Eastern Veil Nebula forms a portion of the Cygnus Loop, a supernova remnant. A star 20 times more massive than the Sun exploded around 8,000 years ago to form this complex (source: Wikipedia). This is another favorite image during the summer months for astrophotographers.

I very happy with how this image turned out as it blows my previous image captured two years ago out of the water. The framing could have been a bit better but everything else went smoothly. I captured 1.5 hrs of Ha on 9/16 and 1.5 hrs of OIII on 6/18 while the moon was out. My only regret was I did not get any RGB data for the star field, however, HOO star field came out better than I anticipated.

This image was fun to process as everything I did in PI looked OK when I tried it. In contrast, I had to do heavy processing on my image from a couple years ago and nothing seemed to look good. I ended up combining it with the simple RGB Combination, however, I did experiment with using PixelMath and doing Ha and OIII combinations in the green and blue channels. I did an Automatic Background Extraction, noise reduction - SNCR, Histogram Transformation, Curves and then switched to Photoshop for a couple of things and that was it.

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.
