This object was barely perceptible to averted vision as an
elongated haze. Finding it under these conditions was simply
a challenge for the scope and observer. The object can be
located (if at all) with an easy sweep 1.5 degrees NW of the
pretty yellow-orange star Beta Cvn, passing midway the two
bright, lovely interacting galaxies ngc4485 and ngc4490. A
DeepSky filter was used, to no perceptible effect. At medium
power (210x), object position was alternately fixated on and
viewed with averted vision, until a slight movement of the
head brought the blur suddenly into view. [I'd be interested
in knowing more about this galaxy - does it have a UGC # or
at least an MCG designation? Is it related to 4485 and -90?]
