Deep Sky , Ursa Major.

Any chart will show the constellation packed with galaxies. Burnham’s “Celestial Handbook” gives some 115 galaxies from NGC 2639 to NGC 5631. Some are very fine, most require dark sky and aperture.
“Bode’s” M81 and M82, both at 10million light years distant. A lovely sight both in a low power fov. They are not easy to find as there are no visible stars nearby. Trick is to follow the diagonal of the plough and then curve up away from the bowl.
M101 is a huge +7.7 “pinwheel” galaxy , face on , but very diffuse.
M109 will show the +9.8 bar.
NGC 4501 and NGC 4088 show the nuclei of these spiral galaxies.
“Coddington’s ” IC 2574 is a +10.4 barred spiral.
NGC 2841 at +10.3 is the best non Messier with spiral arms.
M97 , the “owl nebula”, a planetary nebula , showing some detail with a uhc filter.

At 12h36m49.4s. +62 12′ 38″ you’ll find the location of the Hubble Deep field north. For 10 days the Hubble scope was pointed at an area equivalent to a grain of sand at arms length.. this is above Alioth and Megrez. The faintest galaxy was +30 magnitude. Looking back to 1000 million years after the Big Bang.
Should you get to a dark sky, the bowl and surrounds of Ursa Major are packed with galaxies looking out into deep space . A very useful area leading to the Coma, Canes V and Virgo galaxies.
Clear skies ! Nick.
