Size(s): 10.7x4.4'
Position: 12:36 27:58n
Magnitude: 10
Personal "rating" (at this aperture, and sky condition): B-
Interesting object, primarily because of the foreground stars.
Large number of 13th magnitude and dimmer stars come into view
in the starfield when magnification is increased on this object.
Particular prominent, an upside down lazy "L" at one end of 3 approx.
13 magnitude stars.
The galaxy is med sized, bigger than many NGCs that I have been observing
of late in CVn and UMajor... and a bit dimmer, especially at low power.
In the eyepiece it was set vertically, and was long and quite plump, a bit
flatter on one side, and fairly featureless.
thanks!
