Star hopping may take some getting used to since you can see more stars through the finder than you can see with the naked eye. And, some objects are not visible in the finder. One such object is M57, the famed Ring Nebula. Here’s how to find it:
1.FindtheconstellationofLyra,asmallparallelogramvisibleinthesummerandfall months. Lyra is easy to pick out because it contains the bright star Vega.
2.Start at the star Vega — Alpha (α) Lyrae — and move a few degrees southeast to find the parallelogram. The four stars that make up this geometric shape are all similar in brightness, making them easy to see.
3.Locate the two southern most stars that make up the parallelogram — Beta (β) and Gamma (γ) Lyrae (see figure
4.Point the finder half way between these two stars.
5.Move about 1/2° toward Beta (β) Lyrae, but remaining on a line that connects the two stars.
6.Look through the telescope and the Ring Nebula should be in the tele- scope. Its angular size is quite small and, therefore, not visible in the finder.
These two examples should give you an idea of how to star hop to

Although the Ring Nebula lies between two naked eye stars, it may take a little time to locate since it is not visible in the finder. Note that the scale for this star chart is different from the one on the previous page which shows several constellations including Pegasus, Triangulum, and Andromeda.
