Guillaume Bigourdan discovered NGC 5339 = Big 70 and recorded "mag 13.4, R, 1' dia, no nucleus." His position is accurate.

400/500mm - 17.5" (5/11/96): fairly faint, moderately large, elongated 4:3 SW-NE, 1.8'x1.4'. Broad concentration with an ill-defined core. Bracketed by two mag 13 stars 1.3' SSW and 1.3' NE. PGC magnitude (16.5) is much too faint.
