NGC 5005 or 5033?
      #6297736 - 01/07/14 10:23 AM

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 find 5005 is much easier to spot, so if you only saw one, I'd guess that was it, but I don't know how much you scanned around the area or what your field of view is. It seems *possible* to me that that you were looking at 5033 and 5005 was out of your FOV, but that's not the way I'd bet.

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.

Can't say for sure. I have viewed both galaxies years ago. Canis Ven is a great place to stumble across some nice galaxies and also in UMa and Com.

They're not so close together you'd see them 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.
