The Butterfly Nebula in Gamma Cygni Nebula (James R Potts)

The Butterfly Nebula in Gamma Cygni Nebula

Man I have been working on this for awhile with a lot of trial and error, more error. Mostly in trying to find the Butterfly portion of this area. One of the errors was my last pic, which is a close up of this area as I set up the wrong scope, LOL. This ended up being over 22 hours of data, going back to August of 2022, but if you would see my stacked image of everything, it looks more like a cross word puzzle piece. I think I finally see the Butterfly, which is the image that zooms over top. I decided to post more than just the butterfly as it is a very pretty area of space with lot of cool fixtures, detail, and dark / dusty nebula.

SH2-108 is around 1,500 light years away and only 26 light years across and it is surrounded by the Gamma Cygni Nebula which is deep in the Orion arm of our Milky Way Galaxy. The Gamma Cygni Nebula, named after the bright star shown in the image, is very large and spans over 6 full moons and includes a star cluster NGC 6910. Gamma Cygni is also known as Sadr (which refers to the great celestial Sawn and comes from an Arabic phrase that means "the hen's breast"). Sadr is an unusual class F8 Supergiant that is yellow-white where most supergiant's are blue white or reddish. Sar is in the process of dying and ceased fusing hydrogen in its deep core. Sadr is not part of the nebula as it is in the foreground and estimated to be around 750 light years away.

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.
