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.
