||M 83, NGC 5236, southern Pinwheel galaxy,
||Type SABc spiral galaxy
||13h37m - 29°52'
||M 83 is a magnificient object
with very well defined spiral arms. It displays a very dynamic appearance,
appealing by the red and blue knots tracing the arms. Dark dust lanes
follow the spiral structure throughout the disk, and may be traced well
into the central region to the nucleus, which is only 20" in diameter
and consists of an older yellowish stellar population which dominates the
whole central region, and extends along the barlike structure.
A wide field image taken with a 6" refractor is here.
