600/800mm - 30" (10/15/15 - OzSky): at 394x; moderately bright, fairly small, elongated NNW-SSE, 40" diameter. This cluster consists of two "knots". The brighter knot on the northwest side appears to have a stellar or quasi-stellar nucleus. A mag 13-13.5 is just off the west-northwest edge, 0.7' NE and another mag 13.5 star is 1' SSE. Mag 9.5 HD 271126 is 2.8' NNE and mag 9.1 HD 35141 is 9.5' E.
