The Iris Nebula - NGC7023

Been up at our place in Overgaard for a little over a week now. This is new moon time for this month and I brought my Redcat 51 setup with me. I was looking for a target that I could image over a number of clear nights and the Iris Nebula looked to fit that bill nicely. I've seen others image this object and I will be honest, once I finished my pass I was a bit surprised of my results compared to others I've see. Most of the other images I've seen others take (On FB, not here in Astrobin) have been details of the central core, usually way over saturated and no details of the dark lanes and nebulosity surrounding this object. I used my ASI294MM in bin 1 mode on my Luminance and with the Bortle 1 skies of Overgaard I was blown away by both the shear number of stars in the field of view but the significant gas and dust clouds in the area. My trusty Redcat 51 came through again I think and I'm really liking this ASI294 with the very small pixel (2.3um) bin 1 mode. It keeps my images from being under sampled due to the large FOV of my Redcat.

I did take a series of OIII and Ha subs but I did not incorporate them yet in this image. I've got to read up on how to do that best. What I have here is pretty much a standard LRGB workflow in PI with some, but very little, Photoshop work.

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.
