NGC 7023 The Iris Nebula

I ran an experiment with using Luminance, Red, Green and Blue filters where I captured the Luminance (entire visible light spectrum) with high resolution (1x1 binning) and the color filter subframes with 2x2 binning (1/2 resolution, more light per combined pixel). I tried short exposures to preserve as much of the bright core of the reflection nebula as possible. The luminance data was comprised of 30 and 60 second exposures and it turned out nicely with good detail. Due to a camera or image download and save problem, the 2x2 binned color images had odd artifacts. So, I beat on the color data in PixInsight and blurred it to produce the final image below. For future imaging, I will stick to full resolution 1x1 binning image capture.

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.
