Spiral Galaxy M64 (NGC 4826), type Sb, in Coma Berenices

RA 12 : 56.7 (h:m); DEC +21 : 41 (deg:m); Distance 19 million light years;
Visual Brightness 8.5 (mag) ; Apparent Dimension 9.3x5.4 (arc min)

M64 is the famous Black Eye galaxy, sometimes also called the "Sleeping Beauty galaxy". The conspicuous dark structure is a prominent dust feature obscuring the stars behind. This feature also enables one to determine, or at least estimate, which of the galaxy's sides is nearer and which more remote; in case of M64, it seems that the southern side is nearer to us.
