This is a two-panel mosaic consisting of 4 hrs per panel using an Optolong L=Pro filter.  I'll add narrowband to this in the future.

Processed in PixInsight. I had a difficult time combining the two panels in this mosaic without showing an obvious seam.  The usual use of the GradientMergeMosaic tool resulted in numerous "pinched" stars in the overlap region, maybe because of the great star density in the overlap.  In the end, I used PixelMath to select from either one panel or the other and not try to overage or overlay in the overlap region.

Located left-to-right in the image:

IC417, a relatively small emission nebula in the constellation of Auriga. It lies near the much more observed nebulae IC 410 (the Tadpoles) and IC 405 (the Flaming Star). It is sometimes referred to as the Spider Nebula as it appears to be attacking the nearby Fly Nebula (NGC 1931 - out of frame to the left). The bluish clouds of gas at the top are locations of new star formation.

IC410, the Tadpole Nebula, is an H II region located approximately 12,400 light-years away in the northern constellation Auriga. It is associated with the young open cluster NGC 1893. The dusty emission nebula IC 410 is ionized by five hot, blue, O-type stars. These massive stars are believed to be the main sources of ionization in the region. They emit high-energy ultraviolet protons that excite the nebula and make it glow. IC 410 was named the Tadpole Nebula because it hosts tadpole-shaped dark dust clouds that appear as if they were swimming toward the center of the nebula. The tadpoles of IC 410 are gas globules, small dense knots of dust and gas that give birth to young stars. They are composed of denser and cooler dust and gas.

IC405, the Flaming Star Nebula, is an emission and reflection nebula located approximately 1,500 light-years away in the northern constellation Auriga. IC 405 is illuminated by the young O-type main sequence dwarf AE Aurigae. It was named the Flaming Star Nebula because it contains extensive smoke-like filaments that make AE Aurigae look like it is on fire in long-exposure photographs. The nebular material that looks like smoke is mostly composed of hydrogen, but the dark filaments are made up of carbon-rich dust.
