Iris Nebula HaLRGB NGC7023

I captured this data back in 2017 with an imaging Newt. My skies have been pretty poor lately and I'm revisiting some older data.   The Iris is a beautiful target and I as I processed this I remember being surprised by how the Ha enhanced the image. I'm not sure really about how true the Ha signal is, but it did come through pretty strong in the Ha integration. Like many regions of the sky there is often a thin Ha signal, so perhaps there is just a permeation of Ha across this area. It's subtle but I think from a pretty picture point of view it offers a different palette than most often adopted for the Iris.

C&C 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.
