NGC1907 is an open star cluster in the constellation Auriga (German: Fuhrmann), about 4200 light years away from us, and has an extent of about 5 light years. It contains only about 30 stars of the 11th magnitude. NGC1907 is located only about 30' south of M38, about 700 light-years in front of M38 (NGC 1912), one of three open star clusters in this constellation.



Messier 38, also known as Starfish or PI Cluster (German: Seetern), is about 2750-3480 light years away. M36 and M37 are often mentioned together with M38. The cluster contains more than 100 visually visible member stars spread over an area of about 15 light years. With an age of 290 to 320 million years, Messier 38 is still a very young star cluster. It is located on the outer edge of the local Milky Way spiral arm, also known as the Orion Arm.



IC 417, also known as the Spider Nebula, is an emission nebula with an embedded open star cluster in the constellation Auriga in the northern starry sky. It is an estimated 7500 light years away from the solar system and has a diameter of about 26 light years.



NGC 1931 is a reflection and emission nebula and star forming region estimated to be 10,000 light years from the solar system. The "Fly", sometimes referred to as "the little Orion Nebula" can be found at the top left of the widefield image. The comparison with the Orion Nebula is because it also shows similar trap stars in the center.
