IC 405 - Flaming Star Nebula
A reflection and diffuse nebula in the constellation Auriga. The most interesting object is its brightest star, AE Aurigae, which probably originates from the region of Orion's belt. AE Aurigae is a variable star that was ejected from the collision of two binary systems along with two other stars, Mu Columbae and 53 Arietis. Mu Columbae is located in the constellation Columba in the southern sky and 53 Arietis in the constellation Aries. The stars move away from each other at a speed of approximately 100 km/s, and the location of the original collision can be determined by the trajectory of their movement. Such stars are sometimes called runaway stars.
The total exposure time is more than 18 hours, which in my opinion is the optimal time for this subject and DSLR. A longer time will not bring many details, but the processing of background noise is more demanding. In the end, quite a lot of detail was obtained from the nebula. It would certainly be interesting to photograph it in the H-alpha band as well.
