The supergiant star Gamma Cygni, better known as Sadr, is located in the center of this beautiful Hydrogen II emission region, along with a complex of stars, dust clouds and glowing nebulae along the plane of our Milky Way galaxy. The field of view extends over 3 degrees (six full moons) in the sky and includes the emission nebula IC 1318 and the open star cluster NGC 6910 (toward the top left of the image). Formed like two glowing cosmic wings separated by a long dark dust alley, IC 1318's popular name is the Butterfly Nebula. Distance estimates from Earth for Sadr are around 1,800 light years, while the estimates for IC 1318 and NGC 6910 are between 2,000 and 5,000 light years. The image is a 6 hour exposure shot from our Alpine yard night before last.

Messier 100 is a spiral design, starburst galaxy, that is seen almost face-on. It is one of the largest and brightest galaxies of the Virgo cluster. As M100 is moving through the Virgo cluster, it is slowly losing some of its gas.

Messier 104 appears as a very small object, but it holds the biggest supermassive black hole ever recorded in any nearby galaxy. Despite its small size, it is a popular target among amateur astrophotographers because of its beautiful dust lanes that cross in front of its luminous center.

The Crescent Nebula (NGC 6888) is a 25 light-year-wide emission nebula in the constellation Cygnus. This “cosmic bubble” in space owes its striking appearance to a central Wolf-Rayet star (WR 136) that pushes the hydrogen and oxygen atoms outward.

The only Messier object in the constellation Gemini, Messier 35 (M35), also called NGC 2168 or the Shoe Buckle Cluster, is a relatively young open cluster of stars about 150 million years old. Open clusters are groupings of stars that are loosely gravitationally bound. They tend to form from the same cloud of gas and dust, so their stars share characteristics like age and chemical composition, which can be helpful for studying how stars form and evolve. Over time, tidal forces within a host galaxy may overwhelm an open clusters’ gravitational pull, and its stars may disperse into the galaxy.

Overview

Messier 13 (M13), also known as the Great Globular Cluster in Hercules, is a dense, spherical cluster of hundreds of thousands of stars in the Hercules constellation. It's one of the brightest globular clusters visible from the Northern Hemisphere and is best seen in July. Appearance and visibility: M13 appears as a fuzzy ball of light through binoculars. With a telescope, its dense core reveals countless stars packed together.

One of the most popular star clusters.

Located in the constellation Monoceros (the Unicorn), NGC2264 actually designates two astronomical objects: the Cone, a diffuse nebula located in the south, and the Christmas Tree, a young star cluster located in the north. NGC2264's brightest star is S Monocerotis.

The Tadpole Nebula, also known as IC 410, is a dusty emission nebula in the constellation Auriga, roughly 12,000 light-years from Earth. It's named for its elongated dust clouds that resemble tadpoles swimming towards the center.

The nebula is over 100 light-years across and contains two tadpole-shaped pillars of gas, called Sim 129 and Sim 130. The heads of the tadpoles are the remaining globules of the once-majestic pillars, eroded by stellar winds into their current shape.
