NGC_6888 Ha and OIII

First attempt at Narrow Band imaging. Second night was all OIII but, the moon did rise about 2 hours into the session.

Description: Reprocessed the data using DBE, after the HOO pixel math, to try and take care of the light/moon pollution on the right side of the image. Slightly different curves adjustments, trying to bring out more of the Ha (red).

C

Description: An additional 2 hours of Ha data and some new processing techniques and scripts in PixInsight. Utilized the NSG script on my OIII data, image tweaks made on a starless image and blended back into the original.

Description: This should be the final update for this image, I am considering this one done for now and moving on to a new target.

Gathered an additional 4 hours of Oxygen III data. Reprocessed all of the data using PixInsight. WBPP to stack, align, and register. Dynamic Crop of the Ha and OIII masters as well as DBE and EZ Denoise on each. Pixel Math to create the HOO image (R-Ha, B-OIII, G-65% OIII, 15% Ha). Starnet used to create a starless image. Curves and Histogram Transformation done on the starless image and then blended back into the original using the Blend script. EZ Star reduction (Adam Block method) to produce the final image.

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.
