Nebula, supernova remnant M1
Nebula, supernova remnant M1 or Crab nebula is in the constellation Taurus (Tau).
Equatorial coordinates (epoch J2000):
Visual magnitude: 8,4m
Optimum magnification for a telescope with observations of M1, depending on the aperture of the telescope (D), is about D/6-D/3. Higher magnifications of course add details, but lead to a strong drop in the brightness of the image, making it difficult to observe.
