M101
M101
is
nice
and
simple
to
find.
In
the
Constellation
of
Ursa
Major
follow
the
handle
of
the
Plough
to
the
double
star
of
Mizar
&
Alcor
and
Alkaid.
M101
is
just
above
the
end
of
the
handle
(if
the
pan
was
the
correct
way
up).
The
Galaxy
is
the
tip
of
an
imaginary
triangle
with
Mizar
and
Alkaid
making
up
the
bottom
corners
of
the
triangle.
