The Iris Nebula - NGC 7023

Due to bad weather conditions, I took me a month to gather the data required to produce a first image of the Iris Nebula.

I started good with 4+ hours on luminance, and could do the same for the blue filter, but green and red - particularly red - suffered from bad weather. I could only gather 20 minutes without clouds on red, not enough to get rid of satelites trails, so I integrated even the most cloudy frames.... and heavily used DBE in Pixinsight to have something manageable...

Therefore, lots of hours in Pixinsight and Photoshop to produce that image. Would have loved being able to push it more, but it require more signal, as always.

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.
