This galaxy made me think about writing a book about suburban 
galaxy hunting! In this session I viewed Hickson61, Hickson 44,
NGC4567(nice), NGC4654,NGC4216,NGC4477,NGC4459,NGC4565(wow) and this, NGC4710.
Most of these are in Virgo and Leo. This galaxy is one of the few that 
stands out against the "grey" suburban skies at all magnifications. High 
surface brightness.
Very interesting (but small) object. It looks much like a flying saucer 
edge-on, kinda like a small version of M104. However, instead of there being 
a dark lane running along the axis, there is either a real, or illusionary 
darkening/mottling, whatever, on either side of the very substantial central 
bulge. These darkenings, run perpendicular to the axis, in effect they seem
to 
give the impression of cutting off, or rather, highlighting the central bulge 
relative to the fairly short beefy extentions on either side. At first
glance,the 
galaxy looks somewhat like the planet saturn, as a kindergartner may 
draw it edge-on, or perhaps a juvenille drawing of a flying saucer.
(in actuality, when edge on , saturns rings are actually thin and even
disappear)
