Aligning The Finder Scope - SKY-WATCHER ESPRIT 80 ED Super APO Instruction Manual

Aligning the finder scope

The 9x50 erect-image finder scope is a small fixed magnification scope mounted on the optical tube.
When it is correctly aligned with the telescope, objects can be quickly located and brought to the
center of the field.
The alignment should be done at first use and over time if the alignment is no more accurate.
Alignment is best done outdoors in day light when it's easier to locate objects
If it is necessary to refocus your finder scope, sight on an object that is
at least 500 meters (or yards) away. Loosen the locking ring by
unscrewing it back towards the bracket. The front lens holder can now
be turned in and out to focus. When focus is reached, lock it in position
with the locking ring
Choose a distant object that is at least 500 meters (or yards) away and
point the main telescope at the object. Adjust the telescope so that the
object is in the center of the view in your eyepiece.
If you are using the star diagonal the image will be left/right
inverted, like images in a mirror.
Having an erected image, the view you have in the finder
scope has the same orientation as the landscape.
Check the finder scope to see if the object, centered in the
main telescope view, is centered on the crosshairs. If not
unscrew the three blocking rings on the rear ring, then adjust
the three small screws to center the finder scope.
Do not over tighten the screws when aligning the finder
scope. When the finder scope is correctly oriented, screw the
three blocking rings in position.
