This imaging project is a reprocess of data collected in September of 2021 of DWB 111/119 - The Propeller Nebula - 10 hours in SHO.

The Propeller Nebula is a region of emission and dark nebulae located in the Cygnus X Complex - about 4600 light-years from Earth.

I was never completely happy with the original image - thinking it looked like a pastel painting and a bit overdone. I wanted to see if new tools and techniques could do better. You can see that image below:

I must admit that I had a hard time with this image. Some images practically process themselves. Others, like this one, are a struggle.

My initial reprocess version was pretty understated for me - given that I am a high-color guy. But as I shared this early version for feedback, several suggestions were made for improvement, and I returned to the drawing board.

Here was my initial attempt:

I am done with the project with this last version of the image. I am unsure how much I helped or improved this image - you must judge that. But I have spent enough time on it for now and am closing this effort. I think the overall detail and color level have improved, but some may still like the look of the original image better.

The story of this reprocess - along with full processing details and a step-by-step walkthrough of the processing steps can be found here:

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.
Dismissals 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.
