NGC 6888 (Crescent Nebula) HOO narrowband

This is a four-panel mosaic image of NGC 6888, the Crescent Nebula, in HOO narrowband color. Most of the subs were acquired from the city during a period when the moon was nearly full, so the image isn't as deep as it could be. The blue halo from the OIII filter did not show up at all, in fact. However, the seeing was quite good, so the details are rather sharp.

One of these days, I am going to get some good imaging weather without the full moon, and I'll do something besides urban back yard narrowband imaging!

Description: This image is a 4-panel mosaic shot with the C11 Edge at f/7. Since the O-iii data for this image were so weak (due to shooting from an urban location), I should have gone with the monochrome H-alpha version shown here. Some noise reduction was applied in Topaz DeNoise AI, which is working wonders with my H-alpha data.

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.
