Description:
Very faint nebula in Cygnus, still not too hard to see in these
conditions and with this aperture. Dark nebula B 168 is a striking
sight, making a fine binocular pair with M 39. No detail visible
inside the nebulae [bright or dark]; the cluster looks very fine,
and it is well resolved, except for two stars. Very nice nebula.
