Here is a widefield image of IC 410, an emission nebula about 12,000 light-years from Earth, in the constellation Auriga. Near the center of the nebulous region is a star cluster ( NGC 1893) and just to the bottom right of this cluster lies two structures that resemble tadpoles. These structures are made of leftover hydrogen and dust from the formation of the star cluster and the "tails" are from the solar wind coming from the stars of NGC 1893.
This was imaged using red, green and blue filters and taking 6 minute exposures stacked, to improve the signal to noise, for a total of 1 hour 18 minutes in the red, and 1 hour in each the green and blue filter.
Fifteen minute exposures were taken through a hydrogen alpha filter for a total of 5 hours and 15 min. integration time. Many emission nebulas are composed of hydrogen and when excited by nearby stars they glow red. Using a specialized filter like the hydrogen alpha filter enhances the detail in the nebula.
