Default ASTRO: NGC 2071

NGC 2071 is a reflection nebula just north of the far more famous M78
some 1300 to 1600 light-years away in Orion.

The nebula houses many protoplanetary disks. One is the smallest known.
It is seen by radio not optical telescopes like mine.

Information on other young stellar objects can be found at this paper:
http://arxiv.org/PS_cache/arxiv/pdf/...111.5469v1.pdf

While NGC 2071 appears to be part of the same molecular cloud as M78 I'm
finding most papers on NGC 2071 saying its distance is 1300 light-years
while M78 papers put it at 1600 light-years. It could be due to the
measurement to 2071 dating to 1982.

I wanted more data on this one but after two months of lousy skies in
this part of the sky I gave up. This year isn't looking any better for
this part of the sky.

Mighty image Rick. I don't think I have seen more detail in NGC 2071 before.
