Planetary Nebula Messier 97
Messier 97
  • Description: Planetary nebula in Ursa Major, on the left side of the picture. The galaxy on the right is Messier 108. This image is a digital composite of two film images - one colour, one B&W. M97 (NGC3587) is a really nice planetary nebula. Not the brightest target at 12th magnitude measuring in at 3.4 arc minutes across but is really nice in a large scope under dark skies or with a light pollution filter.

  • Scope: 8" f6 Newtonian for both.
  • Exposure: 55 Minutes tech-pan, 40 minutes Ektachrome
