Personal "rating" this aperture: C+
I had the pleasure of FINALLY being able to draw out this 
diffuse galaxy from the light pollution, mainly in the 14.5".
It was a night with good clarity, about 4.9 limiting magnitude.
A dim, hard to find, large, fairly uniform glow near a weak
double star (just east of the double I think) in the 14.5". The
center brightened slightly, and there was good evidence of
structure, lumpiness in the face-on galaxy, particularly at
130x. Notably easier to detect with true dark adaptation,
partience, and a deep sky filter. Two nights later I was 
barely able to pick out the glow with mag. 4.7 skies in an
8" SCT. Only found it because I knew where to look!
