This was my first observation of this 9.5 magnitude, M4 red dwarf since last summer. Barnard's Star has an absolute magnitude of 13.2 and has a luminosity only 1/2300th that of our sun's. It is the closest star, other than the sun, visible from mid-northern latitudes and has an extremely high proper motion of 10.31"/year. Barnard's Star was easily visible to the northeast of the apex of the "V" of faint stars on the finder chart in _Burnham's Celestial Handbook_. I used magnifications of 121 and 159x.
