Notes: In this image B 34 is large enough that it seems to blend into the star field ...a look at the Barnard 'discovery' Plate 7 (go to Browse by Region: "7 - Region of the Cluster Messier 37 in Auriga" ...) indicates why Barnard cataloged this as one of his 'dark spots' ... but my images shows more stars in a smaller field of view, lessening the impact. See here for explanation of "TGU" catalogue.
