Spiral galaxy M64
Spiral galaxy M64 or Black Eye is in the constellation Coma Berenices (Com).
Equatorial coordinates (epoch J2000):
Visual magnitude: 8,5m
Optimum magnification for a telescope with observations of M64, depending on the aperture of the telescope (D), is about D/6-D/2. Higher magnifications of course add details, but lead to a strong drop in the brightness of the image, making it difficult to observe.
The best month for observing M64 is May. At this time, the object is at midnight near its highest point in the sky, that is, it is less affected by light from the lanterns and atmospheric distortions.
For observers in the northern latitudes:the night sky in May is no longer very dark, so try also to observe M64 in April.
