You can avoid the need for a compass if you learn how to spot Polaris.
(The North Star)
If you look at your star charts, you'll find two of the stars in the big
dipper define a line that points right at Polaris.
On M57, you'll probably need about 60 power to see the hole in the
donut. I typically observe it at about 90 power in my 4.5" refractor.
If you pick up a 9 mm eyepiece, you'll have 53.33 power without your
barlow, and 106.66 with it.
