Description:
M51 was just rising out of the light dome. It was easily recognizable
along with its companion NGC5195. M51 was to the left with the companion to
the right. A large bright haze surrounded M51 to distinguish it from
its smaller companion. With averted vision I was barely able to discern
its spiral nature. One spiral arm arched between the core and NGc5195 to
the west and another arched east of the bright core. It looked as if
brackets surrounded the core rather than arms spiraling in towards the
center. I will surely revisit this when it gets nearer zenith where the
sky has 6mag visibility. I used both 60x and 120x with the
higher magnification showing slightly more detail.
