| Notes: | This amazing area of the southern Milky Way lies a little north of the midpoint of a line between the M 4 Globular Cluster and the M 8 / M 20 complex. There are many dark nebula in this area, with B 72 being perhaps the most photogenic. B 68 is the very dark spot at the lower right of B 72. See a link to my 14.5" Newtonian film shot |
