The constellation of Auriga, the Charioteer, offers us a very deep look into the winter Milky Way. Here we look in the direction of our galaxy’s rim. Therefore Auriga is very rich in galactic clusters. A beautiful binocular field can be found near the star chain formed by 16, 17 and 19 Aurigae. This interesting star chain looks like a wide open cluster, which can be seen with the naked eye on a dark night. While they form not a real cluster, these stars are all about 230 to 450 l-y away. At less than one degree to the NW, the bright star AE Aurigae can easily be found. AE Auriga probably is a runaway star, which was born in the M42 region. At a distance of 1500 l-y, AE Aurigae is moving through a cloud of gas and dust. This interstellar cloud around AE Aurigae is called IC 405, the Flaming Star Nebula. IC 405 is illuminated by the passing runaway star. A small portion of this reflection and emission nebula can be seen with averted vision in a pair of binoculars. Look for a small diffuse glow SE of AE Aurigae. Let’s go back to our first star chain. Another fine treasure can be found in the opposite direction of AE Aurigae: the young and loose open cluster NGC 1893, embedded in the pale emission nebula IC 410. A pair of binoculars will show the combined glow of the cluster and the surrounding emission nebula in which it was born. NGC 1893 is 15.600 l-y away and has a true diameter of 54 l-y. IC 410 has an impressive diameter of about 150 l-y. IC 405 and AE Aurigae are about 4 times further away than the central star chain, while NGC 1893 and IC 410 are maybe 40 times further away.

The emission glows in this sketch are excellent.

This section of the sky is always fascinating to study during clear and cold Winter skies. There is a multitude of clusters and star groupings as you depict. Thank you for sharing it with us all. I look forward to your future observations.
