Apogee U16M at -25C, Astrodon 3 nm H-a, SII and OIII and Generation 2 LRGB filters. Guided with SBIG ST-402 on Astrodon MonsterMOAG off-axis guider.  Data acquired in MaximDL4.62 automatically with CCDAutoPilot4.  Narrowband color using the Hubble Palette where Red = SII, Green = H-a and Blue = OIII with RGB stars blended in. The field is about 35 arcmin and north is down.

IC410 is a large  nebula (100 light years across) in the constellation Auriga energized by the bright cluster, NGC 1893, containing hot stars that push away gas, giving the appearance of a "hole", similar to the Rosette Nebula.  It is only 12,000 light years away.  The two objects at the lower right corner are often referred to a "tadpoles", which are regions of cooler, denser gas that resisted the erosive effects of the hot cluster of stars.  They are 10 light years long.
