| Notes: | This field is the last and probably the most interesting of the Dark
Nebulae I imaged in Auriga during January 2007. The positions seem fairly close to the
cataloged numbers, but there seems to be four 'dark' spots here ... from
West to East (right to left) are B 26, B 27 and B 28 ... the middle of
the 'three' (B 27) is clearly two dark spots aligned North-South.
vdB 31 (LBN 798) is the barley discernable
nebulosity between the two 'bright' stars just under B 28. Descriptions from the on-line Edward Emerson Barnard "A Photographic Atlas of Selected Regions of The Milky Way":
