Description:
Took a while too because it was at the zenith and took me to a bad position 
lying down :-(.  But what a beautiful sight.  I couldn't find it with the 40mm, 
and found it obviously not a star with my 30mm (30x).  Blue looking without a 
doubt.  I jumped to my 8mm TV Radian (110x), definitely looked like a blue 
ball.  At 146x and 176x (6mm TV Radian) something interesting happened.  I saw 
a star nearby (the brightest star of the 3 in the picture - see link below) 
with *averted* vision.  The ball is still bright, much brighter than mag 9.0 
would suggest and definitely much brighter than M57. Then, I used my 4mm Radian 
(220x) and 3mm Radian (293x) - wow!  Definitely, the right mag for the ball.  
The thing that caught me was that I can now see the nearby 13.2 mag star with 
*direct* vision.  This observation that I can see better with direct vision at 
high magnification really surprised me.  Anyway, the ball looked blue all the 
way up to 293x.  There may be even a hint of the internal oval shape, but I 
guess it was my "oval" imagination.  No central star can be seen.
My favorite!
