Barnard 95/LDN 406

Barnard 95/LDN 406 is a dark nebula in western Scutum about 2.6 degrees
northeast of M16. That puts it rather low in my skies. I need a very
good night to work this low. Seeing and transparency are usually poor
at this low altitude. This was one of the very few good nights I had in
2013. While most sites say the distance to dark nebulae in Scutum is
about 650 light-years the one paper I found giving a distance to it says
400 parsecs which would be twice that distance or 1300 light-years.

There's one asteroid in my image. It is in the lower left quadrant and
rather lost among all the stars but does show up as a rather bright
short line angled upward to the right. It is (99252) 2001 LJ1 at
magnitude 17.2. I doubt I'd have noticed a typical magnitude 19
asteroid I usually pick up. While this was a good night for 2013 the
variations in the asteroid trail show sky conditions varied through the
exposures for the L frames with the last two being less transparent than
the first two and likely through the color frames as well.

A really nice hole in the sky...
Stars look very good for such a low object.
