Re: (IAAC) Obj: anonymous(?) galaxy 12h29m +42o12m - Inst: Newt 20" f/5
Will, I will have to go back to my original handwritten notes, to
see if any other details on this little bugger might be available,
e.g., what made me look for this obscurity in the first place!
Thanks for the question, though: it would be nice to scratch this
one off my "what did I see???" list at last. :)

Site classification (urban, suburban, rural): semirural
Limiting magnitude: 6.0 (ice haze)
Seeing: 2 - good
Moon up: no
Instrument: Newt Reflector 20" f/5 (dob)
Magnification: 70x, 210x, 360x
Filters used: None, Lumicon Premium DeepSky
Object: anonymous(?) galaxy 12h29m +42o12m
Category: Spiral galaxy
Constellation: CVn
Data: mag 12.5? size 2'x1'?
RA/DE: 12h29m +42o12m
Description:
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?]
