IC 410 is a region of faint Ha nebulosity surrounding the open star cluster NGC 1893.  The cluster itself is small and located just below center, underneath the central dust region of the nebula.  This nebula contains complex wisps of gas and is a beautiful target for Ha astrophotography, although it is surprisingly difficult to find detailed information about this region on-line.  The two prominent filamentous columns located below the center are called the 'tadpoles' and may have been blown outward as a result of radiation emitted from the open cluster (notice how their "tails" generally point away from NGC 1893). This image is a 3.5 hour exposure with 2 hours of hydrogen-alpha data. The image was taken with the Hyperion 12.5" astrograph and an STL11000m CCD camera on January 13, 2010
