A star that exploded some time after
the majestic Egyptian pyramids were made left a magnificent shell of ionized
gas larger than the orbit of the Trans-Neptunian objects in our own solar
system. That orbit is where some unknown and known dwarf planets like the old
pal Pluto, survive far away from the sun.
A telescope is a time-machine that
allows the observer to look at the past of the universe. The image of the M57 I
saw last October was actually its light that started a long journey to earth
more than 2000 years ago.
Finding the Ring Nebula is pretty
simple and it is definitely worth star hopping from either one of the two stars
Sheliak (β Lyrae) or Sulafat (γ Lyrae) in toward the other. In binoculars, both
of these stars fit in the FOV and the Ring Nebula is almost in the middle of
them; perhaps leaning a little towards Sheliak. Unfortunately, the ring does
not show its real shape in binoculars, but instead it looks like another
stellar object, similar in brightness to the other stars around.

Here is the view with my 6” SCT and
100x, in my opinion, the best view of the nebula with my scope. I still could
not see the planetary nebula nucleus (PNN) but I definitely saw the shell
around it. It looked like a smoky and blurry oblate donut with some senses of
green-yellowish color in the body and red in the edges. Somehow, every time I have
looked at this object with my telescope I wanted to refocus because its
blurriness gave me the feeling that the scope wasn’t perfectly in focus, but by
looking at the stars around I could see that the scope was perfectly focused
because the stars around were pinpoints of light.
If there are big reasons to have a
telescope, definitely M57 is one of them. It is certainly one of the best views
in the sky and as I said before, middle-high magnification makes it possible.
For those telescope owners, I hope they
can enjoy this view as much as I have enjoyed.
Clear skies,
LG
