Star Hopping
One way to find celestial objects is to use a process called "star
hopping." Star hopping is done by using bright stars to "guide" you to
an object. For successful star hopping it is helpful to know the field
of view of your telescope. Your ExploraScope has a field of view of
approximately 1°. Therefore, if you know an object is 3° away from
your present location, you just need to move 3 fields of view towards
the desired object. Let's try a popular example: The Andromeda
Galaxy, also known as M31.
To find M31:
Locate the constellation of Pegasus, a large square visible in the
fall in the eastern sky, moving toward a point overhead, and in
winter months it's overhead moving toward the west.
Start at the star in the northeast corner—Alpha (
α
)
Andromedae.
