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.
