6.
Turn the focuser knob to bring the target in focus and centre the object in the
eyepiece.
7.
Re-tighten the tripod/mount movement locks so that the telescope remains
stable during the finder-scope alignment procedure.
8.
Look through the finder-scope.
9.
Use the collimating thumb-screws on the finder-scope’s bracket to align the
finder-scope so that the cross-hair is precisely over the same object in the
eyepiece. You only need to use the three thumb-screws on a single ring to align
the finder-scope.
The finder-scope is now aligned to the main telescope. You can check and refine
alignment on a night sky object like a star if required.. Please note that the view will
not be the right way up and views will differ depending whether a diagonal is used
or not. If you do not use a diagonal you will need an extension tube to reach focus.
Using the AR80S
If you are new to observing it is advisable to first use the telescope during daytime
to learn how it operates. First mount the telescope on a tripod or telescope mount.
Once the optical tube has been mounted attach the finder-scope, then attach a
diagonal and low/medium power eyepiece i.e. 20mm. Make certain that all parts are
secure.
Simply choose a distant target to observe like a large building or large tree. Point the
telescope towards the target so that it roughly lines up with the target.
Look through the finder-scope, if you have not aligned it already this is a good time
to do so before you proceed. Move the telescope until the target is visible in the
finder-scope and positioned under the cross-hair.
