The easiest way to ﬁnd your way around the sky is using a technique called “starhopping.” To get started, measure the

ﬁeld of view of your ﬁnderscope.

Measuring the Field of View of Your Finderscope.

1. Look in the sky and locate a constellation with bright stars. You can use your planisphere to help identify it. Now ﬁnd

the map in your star atlas that shows this constellation.

2. Center your ﬁnderscope on any bright star that you can recognize on the star map.

3. Hold your head 12 inches behind the reﬂective window of your StarPointer ﬁnderscope and move the telescope so that

the bright star is at the edge of the ﬁeld if view of the window (it does not matter which direction you pick).

4. Without moving the telescope, look through the ﬁnderscope window and locate another star near the opposite edge

of the ﬁeld of view.

5. Locate this second star on the chart. Measure the distance between these two stars on the chart using a ruler. This

distance is represents one ﬁnderscope ﬁeld of view on your atlas. You can now use this measurement to locate

celestial objects.

Locating Celestial Objects

1. Once you have identiﬁed an object you want to ﬁnd, locate it on your star atlas. Use the map to determine what

constellation it lies in and what bright stars are near it.

2. Now use your planisphere to locate the constellation in the sky and try to locate the bright stars you found

on the star chart near your target. Move your telescope so that the bright star is centered on red dot of your

StarPointer finderscope.

3. Using the scale you just created, ﬁnd out how many ﬁelds of view of the ﬁnderscope you need to move and in what

direction to go from the bright star to your target. Looking through the ﬁnderscope, move the telescope the same

number of ﬁelds of view and in the same direction as indicated by the map. When you are done, your telescope

should be very close to your target.

4. Look through the lowest power eyepiece you have and see if you can see it. If you don’t see it, you can start a systematic

search of the local area. Look through your eyepiece and slowly move the scope back and forth, up and down. Try not

to move more than one ﬁeld of view of the eyepiece at a time so you don’t miss seeing it. Be sure to move slowly and

take your time. If you still can’t ﬁnd it, don’t worry. Just go back to your bright star and try it again. With a little patience

and some practice, you will be able to locate these objects without much trouble.
