Aligning the Finder
Accurate alignment of the finder makes it easy to find objects with the
telescope, especially celestial objects. Your finder comes installed and
aligned, so there is no need for you to make any changes unless it becomes
misaligned. To make aligning the finder as easy as possible, this procedure
should be done in the daytime when it is easy to find and identify objects in
the telescope without the aid of the finder. To align the finder:
1.
Choose a target that is in excess of one mile away. This will eliminate
any possible parallax effect between the telescope and finder.
Release the R.A. and DEC clamps and point the telescope at your target.
Lock the clamps once pointed in the general direction.
Center your target in the main optics of the telescope using the R.A. and
DEC slow motion knobs.
Adjust the thumbscrews on the finder bracket, tightening one while
loosening another, until the cross hairs are centered on the target seen
through the telescope.
Tighten each thumbscrew a quarter of a turn to ensure that they do not
come loose easily.
Since the image orientation through the finder is inverted (i.e., upside down
and backwards left-to-right), it may take a few minutes to familiarize your-
self with the directional change each thumbscrew makes on the finder.
