Barnard 72, "the snake" is another challenging dark nebula.
Here are observing notes excerpts of one observer, concerning the
visibility of the horsehead. Note the apertures used, and some sightings weren't even under pristine skies. The smallest seems to be about 6", so my 8" sighting isn't much of a feat in light of these, and I'm more inclined to believe Steve Jacobs' 6" Dynascope sighting.
