Description:
Beautiful, quite large and bright deep sky object in
Lyra. It is one of 
the finest and most popular planetary nebula. At 40x I
have easily found 
it, it was looking like a small disc. Switching
magnification easily 
showed its slightly elongated disc nature. I have then
switched to 290x 
to draw sketch, but no further details were visible.
Field of view is 
peppered with many faint stars, even at 290x. Sketch
is available at the URL mentioned below.
