Description:
Found with difficulty even in averted vision, M101 appeared
in binoculars as a faint, HUGE (30') haze, lying just off the
end of a chain of 7 stars mags. 6 - 7, which straggle ESE of
the pretty naked-eye optical pair Mizar and Alcor. M101 can
also be found about 1.5 binoc fields NNE of eta UMa. No hint
of detail could be seen in M101, not even any stellarings in
its indistinct face, but the field of view was striking!
