Even to the naked-eye under these conditions, M33
was visible with averted vision, possibly showing
hints of its inclined disk shape in its faint halo.
With 10x50 binoculars, the shape of the blur became
even clearer, with (perhaps) just a hint of one or
two of the spiral arms yielding to averted vision.
