Data: mag 8.4v  size 8.2'x6.9'
Position: RA 13:30  DEC 47:12
Description:
At 58x (35mm Ultima, 50' true field)the galaxy showed a relatively small,
concentrated core surrounded by a wide nearly circular haze, perhaps 10'x8'.
Spiral structure was occaisonally apparent with dust lanes popping in and
out of view.  Really neat!  
This was a memborable observation for a number of reasons.  The nights of 5/6
and 5/8, 1999 were two of the best skies I've ever observed under in my(whole)
4 years of doing this stuff.  Seeing and transparency were excellent.  I logged
39 objects over the course of the two eveinngs, including the last 25 objects I
needed to complete the Mesier list - and M51 was last.  What a great way to
finish! - Don Clouse, 7/29/2001
