Aligning The Finderscope - Celestron ROYAL OBSERVATORY GREENWICH TRAVEL SCOPE 70 Instruction Manual

ALIGNING THE
FINDERSCOPE
The finder is one of the most important parts of your telescope. It
helps you locate objects and center them in the eyepiece. The first
time you assemble your telescope, you need to align the finder to
the telescope's main optics. It's best to do this during the day*.
* SOLAR WARNING!
Never attempt to view the Sun through any
telescope without a proper solar fi lter
1
CHOOSE A TARGET
Take the telescope outside during the day and find
an easily recognizable object, like a streetlight,
license plate or sign. The object should be as far
away as possible, but at least a quarter mile away.
4
ADJUST THE FINDERSCOPE
Without moving the telescope, use the three
adjustment screws on the finderscope bracket to
move the finder around in the bracket until the
crosshair appears over the same object you are
observing in the telescope's 20mm eyepiece.
TIP:
Try adjusting one screw at a time. Loosen one screw by
half a turn and tighten another by the same amount to
ensure the fi nderscope is securely held in place.

object you chose lies in the center of the view. If the
image is blurry, gently turn the focus knobs until it
comes into sharp focus.
