Ha   360 min (12 x 30 min. bin 1x1)
OIII 450 min (15 x 30 min. bin 1x1)
Lum  180 min (12 x 15 min, bin 1x1)
RGB  270 min (  6 x 15 min each, bin 2x2)
SII, Ha & OIII are mapped to RGB respectivly with 30% RGB added.

IC 410 is at a distance of about 12,000 light-years, toward the constellation Auriga. The emission nebula surrounds NGC 1893, a young star cluster, which energizes the gas. At the upper right are two interesting objects, about 10 light-years long, that are commonly named "The Tadpoles." Their creation by stellar winds and radiation is most evident in that the Tadpole's tails point directly away from the nebula's central star cluster.
