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. http://www.nrao.edu/pr/1998/essdisk/ 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. 14" LX200R @ f/10, L=4x10', RGB=2x10'x3, STL-11000XM, Paramount ME Rick -- Prefix is correct. Domain is arvig dot net |

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