Gamma Cygni Nebula

The Sadr Region around the central star Sadr (γ Cygni) in the Cygnus constellation contains the large H II nebula, Gamma Cygni Nebula (IC 1318). This nebula is partly obscured by dust, creating the Butterfly Nebula (IC 1318B) in the lower left of the image, just below Sadr.

Many other objects can be seen, including multiple star clusters and, most notably, the Crescent Nebula (NGC 6888) to the right of the center of the image.

This image was created with 2,984 × 2 s (1 h 39 min 28 s) integration time. Post-processing was done with #Siril, #GraXpert, #StarNet++, and #GIMP.

This time I documented the whole process in my #blog. If you have a camera, this is for you (no guarantees, though; I just fail along until it works for me): https://blog.picturavis.com/astrophotography-without-equipment/

This was the first image from the s50 for tonight. A view of the #star #Sadr. #seestar #S50 #space #astronomy #amateur

But wait! There is more. Earlier this evening when I set up the s50 decided to view it with that mask attachment that I mentioned came with the dew shield. Decided later to do a comparison with what the Odyssey Pro would produce. Here are my observations of the #Sadr #Star. #unistellar #odysseypro #space #astronomy #amateur #seestar #S50

This evening before leaving the s50 out, decided to try this mask that came with the dew shield. Did not expect that is would detract the star light. Here is what I got when viewing the #star #Sadr. I am sure there is some pretty important information that can be gathered from this. #seestar #S50 #space #astronomy #amateur

Some #star observations from this morning. #Sadr #Eltanin #Schedar #unistellar #odysseypro #space #astronomy #amateur

I'm convinced that #Trump will pick up where he left off from his first term and make moves to increase hostilities everywhere. See #Morocco vs #SADR. There's nothing more (and less) “Presidential" -- and thus cut-and-dried immune behavior -- as #wartime. And he gets to spend whatever TF he wants.

#SkyWatch #Astrophotography I have posted photos of the #CrescentNebula before but not ones created with my 250mm lens. This wider field of view shows the Crescent (lower right corner) amidst the hydrogen gas clouds of the #Sadr region in the center of the #Cygnus constellation. The Crescent is a shell caused by colliding gasses after a star explosion and is 5000 light years from Earth. #StillLearning
