Iris Nebula NGC7023

My first mono picture and first use with camera, filter wheel and EAF. I chose the Iris Nebula even though it was very low in the horizon, only 20 degrees, but I was in a bortle 3 zone and wanted to go for something that would be almost impossible to capture from my bortle 6-7 at home.

I still need to learn a lot about the equipment, I used 101 unity gain, but gain 0 would have been better for more dynamic range. I also used filter offsets in NINA as I was capturing a sequence of 3L 1R 1G 1B and then dither, but I have the impression that the stars were a little bit out of focus, I need to check that.

In any case, I'm very happy I took the decision to go into mono, once you start understanding how the capture and processing workflow work, it is not much different or time consuming than shooting with a OSC or DSLR, however the signal is much better.

I hope you like it

Description: Another try editing this nebula, I'm not very happy yet but I think I'm progressing by not overprocessing it

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.
