The Propeller Nebula - Simeis 57

After seeing an excellent version of the Propeller I decided to give this a go, not realising just hard this was going to be to process, I'm still not convinced I have done this justice. The data seemed good but the stacking was a mare.

No matter how hard I tried to remove the green it just didn't look right without it, so I have left it in, arguing that if the Hubble can have green in the Pillars of Creation, then I can have it in my Propeller...lol

It initially proved a pain to stack and finally a good mate had a look and discovered one light frame just wasn't behaving and once removed then it was fine. For the first time I combined in Pixel Maths which allowed me a little flexibility.

It is what it is and it seems like an eternity ago but was in fact the last time we had any clear skies.

The Propeller Nebula (Simeis 57, MRSL 497 or incorrectly DWB 111) is a part of the much larger emission nebula complex Cygnus X in the constellation Cygnus.

Description: I really wanted to try and tame the green and hopefully running a few different scripts and messing with my curves I have succeeded.

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.
