This region of the sky, in the approximate middle of the constellation Cygnus, is brimming with clouds of ionized hydrogen. In this image I have located the bright star Sadr just out of the field of view to the lower right, and highlighted a butterfly shaped section of the nebula. But truthfully, it is hard to point to this section of the sky without getting some interesting and captivating shapes in your field of view. This was imaged in RGB and Hα, with the Hα mixed in to the red channel to add some sharpness and detail. In retrospect, I might have also captured OIII and made a 'proper' bi-color narrowband image out of this as well.

The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae. Sadr itself has approximately a magnitude of 2.2. The nebulous regions around the region are also fairly bright.
This relatively bright region in the constellation Cygnus is famous for its resemblance to the North American continent, including a prominent Gulf of Mexico area. The Wall section is the bright region of Hα emission that runs along the lower edge of the frame. This image is over 19 hours of data, primarily in Hα and OIII, with about an hour's worth of RGB data used for the stars.

So this is a set of data I took earlier this year. I was having some issues with my remote setup at the time and didn't like some aspects of how things were working and so I went off on a troubleshooting sidetrack and never got back to this. Eventually I kinda forgot I had taken the data at all. As it turned out, even with some issues the the data was good enough to make a decent image, although I think it could have benefitted from more subframes. As it is, I ended up with about 8 and 1/2 hours worth of frames, mostly in narrowband, with a typically small stack of RGB data to add back in natural color stars. This object is reasonably bright, and does have signal in all 3 narrowband wavelengths that are typically used. As is often the case, the Hα signal is the strongest, with the OIII and SII signals being noticeably weaker. I would have taken a little more data in SII and OIII to compensate a bit had I not interrupted my data collection on this. IC410, as it is otherwise known, is a nebula in the constellation Auriga, and is located approximately 12,000 light years away from Earth. A number of newborn stars have been detected in this relatively energetic star forming region. The namesake tadpoles can be seen in the just left of center of the image, 'swimming' towards the center of the frame :) Equipment: ZWO ASI1600MM-C Camera @ -15C and Gain:200 Offset:50 Software Bisque MyT Mount Stellarvue SVQ100 Astrograph Refractor, 580mm @ f/5.8 Innovations Foresight ONAG Software: Pixinsight Commercial Version 1.8 Lightroom CC Photoshop CC Innovations Foresight SkyGuard Software Bisque TheSkyX Light Frames: Ha: 28 x 360 secs ( 2 hrs 48 mins) OIII: 26 x 360 secs 2 hrs 36 mins) SII: 28 x 360 secs (2 hrs 48 mins) Red: 12 x 30 secs (6 mins) Green: 10 x 30 secs (5 mins) Blue: 10 x 30 secs (5 mins) 8 hrs 28 mins total Dark Frames: 10 x 60 secs, RGB (10 mins) 10 x 360 secs (1 hr)
