Actually I think you may have observed 7464 and have recorded it in your
drawing. If you look at 7463, you will notice it extends a little out
toward 7465 after the bright nucleus oval. You may have mistaken 7464
for the fuzziness a little further on! You either drew it as nebulosity
or thought there was a smudge there. Or maybe it IS a smudge? Anyway,
what a great drawing. In my Deep Space CCD Atlas North (Vickers), it is
a small round fuzzy dot of an elliptical GX in that spot and is prob,
the reason for the difficulty in observing it. I "don't like" tiny
planetaries for the same reason: they look like stars. Check into this
book; I use the CCD Atlas all the time to check what I see and settle
arguments with myself and others.
