Sadr and the Gamma Cygni Nebula (IC 1318)

Gamma Cygni (γ Cygni,), officially named Sadr is a star in the northern constellation of Cygnus, forming the intersection of an asterism of five stars called the Northern Cross. Based upon parallax measurements obtained during the Hipparcos mission, it is approximately 1,800 light-years (560 parsecs) from the Sun.

Compared to the Sun this is an enormous star, with 12 times the Sun’s mass and about 150 times the Sun’s radius. It is emitting over 33,000 times as much energy as the Sun, at an effective temperature of 6,100 K in its outer envelope. This temperature is what gives the star the characteristic yellow-white hue of an F-type star. Massive stars such as this consume their nuclear fuel much more rapidly than the Sun, so the estimated age of this star is only about 12 million years old.

The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is the diffuse emission nebula surrounding Sadr (γ Cygni) at the center of Cygnus’s cross. 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.

The Sadr region, or IC 1318, is the diffuse emission nebula surrounding Sadr. Photographed with APO107 refractor telescope and Atik 360EX monochrome CCD camera in Åva, September 2019. Exposure was a total of 53min with LRGB and Ha filters.

Photographed with APO107 refractor telescope and ASI 2600MC color camera in Stuvsta, October 2021. Exposure was 20*3min With IDAS LPS D2 light pollution filter and using a new guide telescope with longer focal length.

The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula (NGC 6888). It contains many dark nebulae in addition to the emission diffuse nebulae. IC 1311 is an Open Cluster in the Cygnus constellation and seen to the left in this picture. Mosaik of three pictures photographed with the APO 94 mm refractor telescope and ASI 2600MC CMOS color camera in Åva, November 7th 2024. Exposure was 20 * 3 min for each picture with IDAS LPS D2 light pollution filter. Postprocessing in Pixinsight.
