    A 60mm should have no problem in a dark sky, but here's my 18-inch notes...

    Very bright spiral with impressive structure, elongated at least 5:2 NNW-SSE, ~7.5'x3'. Contains a bright, elongated core highlighted by an intense, stellar nucleus. The halo is noticeably mottled at first glance and a dust lane runs NNW-SSE along the west side of the core. There is a strong impression of spiral structure with an arm attached on the east side that extends to the north and appears to curve towards the west in the outer halo. The halo appears more extensive or slightly brighter on the northern end. A more difficult arm appears to sweep to the south on the west side of the core.
