The Iris Nebula - NGC 7023

Here is the Iris Nebula, a very nice reflection nebula in Cepheus. This one was interesting and frustrating as I collected a good amount of data but I had a lot of noise, particularly chromatic noise. So I went back and re-did my calibration frames and tried again to no avail...

So in the end, I feel like I left a lot of detail out that I think I should have been able to capture. But the bright side is that I believe I have traced the problem to my USB hub.

I also decided to image this at 1/2 unity gain to try to increase the dynamic range. I think that might have worked a little bit.

Anyway, I struggled as to whether or not to publish this and after leaving it in the staging area for a day, I've decided to throw it up on my page.

Any comments or criticism always welcomed and clear skies,

Mike

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.
