Description:
120X- NGC4217 appears as a thin sliver of light with a noticable bulge in the
center. The Galaxy is divided by a thin dust lane along the edge-on view. At
34' E.N.E. lies NGC42358 (M106).

220X-There is a faint star (14.3p) at the extreme S.W. end of the halo. Also
see 11.1P star 42" north of the core and a 8.5p star 2.2' at 20* from the core. NGC4226, Galaxy, 14.4p is just observable as a tiny bright core with direct
vision at 7' S.E.

441X- NGC4217 is cosiderably dimmed at this power, but it is still readily observed with direct vision. The dust lane is prominent and appears to be located to the S.E. side of the major axis of the halo. Also the central bulge seems larger and brighter N.W. of the major axis. This seems to me to indicate the Galaxy is not quite edge-on, rather it has a very small tilt givig the N.W.face a little more exposure. It is intersting object and I will visit it again. (Note: The description in MegaStar states a 7* inclination which confirms my suspicions.)
