The left image is a photo of Barnard's star taken with the Jaegers f5 5" wide field refractor piggy backed on the Manka Memorial Telescope of AAAP and a Nikon coolpix 995 camera (18mm eyepiece/adapter, 8 seconds, F2.6, ISO 800) on 2003/9/16. The center one is a sketch with an 8"/f6 reflector in August 2000. The right image is from the STScI Digitized Sky Survey, POSS-1, 1950-57, obtained from the STScI survey .
Below is a photo with a larger field. It is taken on 2003/9/16 too. The star 66 Ophiuchi is at lower left; the stars at upper right form a big arrow '<'. Some much fainter stars down below form a small arrow '<' too. Between the two arrows is Barnard's star, moving towards the big arrow.
