Description:
HCG44 is a pleasing group that spans about 18'.  As a group, the best view was
at 58x (35mm Ultima, 50' true field).  The larger field yields plenty of
sky around the group resulting in a nice panoramic view.
The individual descriptions following were all done at 135x (15mm Panoptic,
30' true field).
NGC3193 = 11.8b, 1.5'x1.5', E
Small, faint, diffuse core surrounded by a dim circular haze.  Perhaps 2' in
diameter oveall.
NGC3190 = 12.1b, 3.3'x0.9', Sa
Elongated WNW/ESE, maybe 3'x1.5'.  With averted vision the core appears compact
but non-stellar.  Surrounding haze extends mostly (1') SSW of core.  NNE edge 
appears sharper than the opposite, larger side.  (Inspection of images after
the fact suggests that this "sharper" edge I was seeing is a dust lane that
seems to rise well above the plane of the galaxy and is thus silohetted
against the hub and disk.)
NGC3185 = 13.0b, 1.7'x1.1', SBa
Relatively large and roughly circular at about 3'x3'.  A dim core can be
glimpsed with averted vision.  Some other faint spots are evident as well.
NGC3187 = 13.4v, 2.7'x1.2', S
Despite trying to see this galaxy for several minutes, I was never able to
get even a hint of it.  (8" aperture is probably inadequate for this galaxy.)
