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!
