Seen nearly perfectly edge on, this Sa spiral galaxy beams softly in northern Andromeda at 10.8th magnitude, and spans over 15 arcminutes in length. The dust lane which lies in its equatorial plane can be seen clearly here, full of knots and fine pillars and dark lanes. The B-V index (Blue magnitude - Visual magnitude) is very ruddy at .88 which means basically this galaxy is quite yellow/red in coloration from the obscuring dust in its plane.

Just to the lower left of the core, and touching the edge of this galaxy is a tiny companion object, MAC0222+4222 which is 16.5 magnitude and .4 minutes in size.
