Description:
Item Two on the Astronomical League Binocular Deep Sky list for me
tonight was this much fainter (see previous log for Hyades) cluster
in the very near vicinity. The oc was extremely easy to find from
alpha Tau (Aldebaran), by sweeping NE one binocular field to a wide
(2o) trio of orange stars mags. 5 to 7, in an E-W line. Just ENE of
and osculating the middle mag 6 star, n1647 was visible with averted
vision ONLY as a faint blur, elongated slightly N-S, and unresolved.
