B (B = Barnard – dark clouds)
B33-DN-Ori (Mag: –) – Horsehead Nebula; high opacity – very difficult object to detect visually – requested H-Beta is a very helpful, this dark nebula is seen in silhouette against the bright nebula IC434.
B35-DN-Ori (Mag: –) – dark clouds, starless.
B36-DN-Ori (Mag: –) – ‘Ring’ of Betelgeuse` is actually broken into clumpy dark nebulae.

vdB20-BNe-Tau (Mag: +11.6) – Electra Nebulosity (IC349); large and extremely fiant patch of luminosity surrounding the star Merope (23 Tau), located in the Pleades / Seven Sisters (Messier 45 / Caldwell 5) (photo)
