Sky Blossom with a Blue Diamond
I love this shot because it shows the unique diversity of the cosmos in one frame. The emission nebula (sh2-101) at the lower right is an H II region emission nebula in the constellation Cygnus. It is sometimes called the Tulip Nebula because it appears to resemble the outline of a tulip in photographic images. It lies at a distance of about 6,000 light-years from Earth.
The blue ring nebula WR 134 at the upper left is a Wolf-Rayet variable star also located about 6,000 light-years from Earth in the constellation Cygnus and is surrounded by a faint bubble nebula created by the star's intense radiation and fast winds. It has five times the radius of the sun, but is 400,000 times brighter than the sun due to a temperature of over 63,000 K.
This is a result from a total exposure time of more than 9 hours: 600 seconds for OIII, and 450 seconds for Hα and SII, a total time of nearby 9 hours, captured in my Garden Observatory in the Alps in Pongau in Salzburg/Austria with the QHY268M and a 420mm f/2.8 Newton. I developed it with Astro Pixel Processor, Pixinsight and Adobe Photoshop.
