Steve's Notes
=====
NGC 2439
17.5" (1/19/91): at 220x, 70 stars visible in a 10' diameter. Bright, fairly large, elongated N-S. This is a rich, pleasing cluster and includes mag 6.7 R Puppis on the northeast edge. About 1' SW and 2' SSE of R Puppis are two easy but prominent double stars equally spaced with similar magnitudes but with perpendicular orientations (N-S and E-W). The pair 1.7' SSE is PRO 41 (9.2/10.3 at 12"). These wide double stars form a striking group and are part of an elliptical outline of stars with a void in center. Very unusual appearance!
