This Mutt and Jeff of dark nebulae were extremely
noticeable against the starry Milky Way background
tonight, despite (or because of?) the fact cirrus
or haze was evident around much of the sky. B112
was by far the more noticeable of the two "blank
spots", at least in the wide field of Barrie's mod-
ified 12x100 Border Hawk binoculars. In fact, this
squashed oval of darkness really had a distinctly
3-dimensional feeling about it - almost as though
I could perceive that it really was a vast body of
cool, dark material in space. It had a sharper edge
to the W, with the narrower E edge trailing off in
to the surrounding stars of the Milky Way.
--
B318 was noted as a very long extension, diving in
to an extensive "estuary" of narrow, meandering dark
lanes, deep into the clotted stars of the Milky Way.
With the Wild Duck cluster nearby, the sprinkling of
resolved and semi-resolved stars all around, and the
pleasant distraction of the many small (and probably
undesignated?) dark streamers in the field, this was
certainly one of the most fascinating bino fields I
have gazed on in a long, long time...
