Steve's Notes
=====
NGC 2447
18" (3/2/08): very easy with any optical aid (at the threshold of naked-eye visibility) with a few of the brighter stars resolved in 15x50 IS binoculars. The cluster is fairly well resolved at 25x in the 80mm finder. The central region is superb in the 18" at 175x (13mm Ethos) with ~100 stars resolved in the 10' region and richest in the core. Appears fully resolved into mag 10-14 stars. A small, near parallelogram of 4 stars (sides ~40"x20") stands out near the center with numerous fainter stars nearby. The brightest star on the SW side of the cluster is a nice, unequal double (ARA 2066 = 8.3/11.3 at 10").
13.1" (3/24/84): about 60 stars, bright, large, pretty rich. Contains a tight quadrilateral near the center with three faint companions.
8": bright, very rich, triangular-shape, pretty compact, excellent field.
