Ursa Major Galaxies (all night)

The Big Dipper asterism and its home constellation of Ursa Major are very
high in the northern sky in late evening during mid-April - ideal for observing the spectacular galaxies they host in strong binoculars or backyard telescopes on the dark nights this weekend. Draw a line connecting the dipper stars Phecda to Dubhe, and extend it by an amount equal to their separation
to arrive at the galaxy named Bode's Nebula, otherwise known as Messier 81. It's a magnitude 6.9 spiral galaxy oriented not quite face-on to Earth,
making it appear relatively large and bright. A smaller, magnitude 8.4 galaxy named the Cigar or Messier 82 is located half a degree to the north. That allows both galaxies to be viewed together in the eyepiece of a telescope at low magnification. Several other fainter galaxies can be found within a few degrees of Bode's Nebula.
