NGC 7023/LBN 487 - Iris Nebula

NGC7023 is a reflection nebula found in Cepheus. The NGC designation identifies the open cluster within the Iris, while the reflection nebula is cataloged as LBN
487. The familiar blue petals of the Iris are roughly 6 light years in diameter.

I've been procrastinating when it comes to going after this target due to my light polluted location. I finally caved and was pleasantly surprised by what came out of the data. I was also surprised by some of the colors that came out, and the hues are unchanged following color calibration. One very frustrating issue I'm trying to overcome is that the final image in Pixinsight looks completely different when uploaded to this site. Still trying to sort that one out. In the mean time the brightness, contrast, and saturation all have to be adjusted so the uploaded version is true to the original Pixinsight version. As always, comments and critiques are welcome.

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.
