Corwin's Notes
=====
NGC 2685 is the prototypical "polar ring galaxy" where a disk of material
similar to that in a spiral galaxy is seen apparently orbiting around a
cigar-like structure. See Sil'chenko (1998A&A...330..412S) for more
information and references to earlier papers. There is a splendid image from
a 200-inch plate by Allan Sandage in the Hubble Atlas.
Steve's Notes
=====
NGC 2685
48" (4/6/13): this famous polar-ring galaxy (nearest and brightest) was viewed at 488x. It appeared very bright, large, very elongated 3:1 SW-NE, 1.5'x0.5', slightly bulging center (spindle shape), high surface brightness and brighter along the central axis. Well concentrated with an intense core and surrounded by a much larger, low surface brightness halo that increases the size to 2.5'x1.2'. The polar-ring was seen on the northwest side as a faint, low surface brightness outer loop attached to the spindle and bulging out ~20". Periodically the outer edge of the loop popped as a distinct arc and appeared as a semi-ring. A mag 11 star lies 2.4' N.
13.1" (1/18/85): moderately bright, fairly small edge-on 4:1 SW-NE. Contains an elongated bright core. A mag 11 star is 2.4' N of center. The well-known polar ring was not seen.
