Supergiant star Gamma Cygni lies just outside the bottom of this skyscape, featuring a complex of stars, dust clouds, and glowing nebulae along the plane of our Milky Way galaxy. The field of view spans over 2 degrees (126.87 arc min, which is larger than four Full Moons) on the sky and includes emission nebula LBN 47, SH2-109 and the dark rift dark nebula, catalogued as LDN 889. The image is shaped like two glowing cosmic wings divided by a long dark dust lane, receiving the understandably popular name, the Butterfly Nebula (some of this is ref. http://apod.nasa.gov/cgi-bin/apod/apod_search).

The entire nebula complex of which this image is part, is illuminated by a solitary visually obscured class O9 star, and is referred to as IC 1318. It comprises three distinct visible components, IC1318 a, b, and c. IC 1318 b and c constitute a single giant HII cloud bisected by the thick obscuring dust (LDN 889) running between the two components (b and c). The bisecting dust lane is 20 light years thick and is physically bound to the emission nebula and its parent molecular cloud complex.

Though this immense HII region is located visually close by to the class F8 star known as Sadr or Gamma Cygni (in Cygnus the Swan), there is no true proximity between the two: the nebula's distance from Earth is estimated to be about 5000 light years, whereas Sadr is only about 750 light years away, and therefore not related to the nebulosity (ref. http://www.robgendlerastropics.com/IC1318text.html).

I have found several very impressive images of the region and adjacent areas on NASA APOD, each highlighting a different interest aspect of the region:

Last few days I have been experimenting with my Canon 100mm lens on my CCD camera. This to gain experience for imaging during my holidays in Austria. In the end I used 3 nights for this image. The experimenting took its time, but I think this could have been done in one night. At least now I know how it works...

Here is the image info:

Lens: Canon 100mm F2.0 @ F2.8
Camera: SXV-H9
Ha: 14x300s (custom scientific 4,5nm)
OIII: 12x600s (astrodon 3nm)
S2: 12x600s (astrodon 5nm)
Total: 5,2h

Mount: NEQ-6
Guiding: no

These pictures are truly incredible!!!
I just started shooting night shots and they are much, much, much harder then they look. I have a Canon DSLR I have been shooting with, but not having a lot of luck. I've also been playing with my Canon XH A1 to shoot some video shots. It's a ton of fun!

Hello,

I let you here an object that was discovered only in May 2011 by N.Outters!
This elusive squid it was the most dificult object I ever photographed! Even with 11h15m of OIII data the signal is so dim that it is very hard to process!
Here the data:

OU4 nebula in Sh2-129
Takahashi FS102NSV @ 641mm + QSI532WS-M1 + OIII-3nm + Ha-5nm
OIII- 675 min
Ha- 85 min
Photographed from the 17 - 21th of July 2012 @ Portugal.

Regards,
paulo

How would the sky look like if we could see h-alpha radiation with our own eyes? This image comes close. It was made from 9 images made from my backyard using a 100mm Canon lens with a SXV-H9 ccd camera. It's the tail of the Swan (Cygnus).

The full scale can be found here:
