Description:
In Scorpius, just SE of Chi Oph. This dark nebula reveals itself surprisingly
obvious to my 9x63. This is due to its larger size, and a rapid scanning in the
sector clearly shows that there is a "hole" of stars on the location of B43.
This observation is facilitated by the presence stars of the Milky Way, near the
studied area. More precisely, the region where I can distinguish B43 without
problems lies at the centre of the triangle formed by Psi Oph, Chi Oph and HD
150416.
