NGC 5005 or 5033?

These two objects are about half a degree apart in the sky, so I highly doubt you're interpreting light from both of them as one object.

They're not so close together you'd see them as one object.
I stumbled upon something fuzzy in Canes Venatici last night that must have been either NGC 5005 or 5033. I was zooming between 20x and 33x in an ST80. Any guesses as to which one I saw? Is it possible I was detecting hints of gray from both and interpreting as one object?
I, too, suspect you saw 5005, and here's why:
The brightness of both is similar: 5005 is m10.6 and 5033 is m10.8
But. the light in both is not at all uniformly distributed, so the surface brightness of 5005 is a bright m11.1, while the SB of 5033 is a much fainter m13.4
That says that the much higher brightness of the area of NGC5005 is far more likely to be seen easily in an ST80.
