Planetary nebula M97
Planetary nebula M97 or Owl nebula is in the constellation Ursa Major (UMa).
Equatorial coordinates (epoch J2000):
Visual magnitude: 9,9m
Optimum magnification for a telescope with observations of M97, depending on the aperture of the telescope (D), is about D/6-0.4D. Higher magnifications of course add details, but lead to a strong drop in the brightness of the image, making it difficult to observe.
