Description

This object is a grand design spiral galaxy located 140 million light years away in the constellation of Eridanus at a declination of -8 degrees.  It is a magnitude 12.5 galaxy which spans 3 arc-minutes in our apparent view.  This corresponds to a Milky Way size diameter of 120,000 light years.

From our view perspective, the disk is inclined about 15 degrees from edge-on.

The structure of this galaxy is incredible when examined closely.  The bright core is surrounded by an inner region that contains two bright overlapping ovals.  A mid-region ring surrounds this inner region.  Two strong arms extend out from this ring, unwinding for 360 degrees.

The interesting blue face-on barred galaxy to the lower left is LEDA 16607, a bit further away at 170 million light years.  This galaxy is smaller at 70,000 light years in diameter.

This is one of those objects which has been hiding out in plain sight.  It is the small galaxy at the center of IC 2118, the popular Witchhead Nebula, and is seen as the central small galaxy is my wide field image here, labeled in the annotated mouseover view:
