My clear sky charts promised to give be many many blue boxes. It didn't happen BUT I was able to finish collecting photons on this target the night before.
IC 410 an emission nebula (http://coatesastrophotography.blogspot.com/2013/11/ic-410-emission-nebula-about-12000light.html) 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.

Nice colours, Steve. The tadpoles must be pretty small? You're using small pixels at a reasonably long focal length.

Cheers,
Rick.

Thanks Rick, Jase and Paul. Rick, the image scale is 0.68 arcsec/pixel and the FOV is 28x38 arcmin.

Great resolution Steve, I love this field and the tadpoles are very intriguing floating in this pond of colorful gasses..
