Attaching the finderscope to the finder bracket
To install the finderscope onto the telescope you must first mount the finderscope through the finder
bracket and then attach it to the telescope. Toward the front of the telescope tube, near the focusing
assembly, there is a small bracket with a set screw in it. This is where the finderscope bracket will be
mounted. To install the finderscope:
1. Slide the rubber O-ring over the eyepiece end of the finderscope and roll it 2/3 of the way up the
finderscope.
2. Insert the eyepiece end of the finderscope through the bracket until the O-ring presses tightly
between the finder and the inside of the bracket.
3. Tighten the adjustment screws until they make contact with the finderscope body.
Attaching the finderscope bracket to the telescope tube
1. Locate the mounting bracket near the front (open) end of the telescope.
2. Loosen the set screw on the mounting bracket on the
telescope.
3. Slide the finder bracket (attached to the finderscope) into
the mounting bracket on the telescope.
4. The finderscope bracket will slide in from the back. The
finderscope should be oriented so that the objective lens is
toward the front (open) end of the telescope.
5. Tighten the set screw on the mounting bracket to hold the
finderscope in place.
Aligning the Finderscope
To make things a little easier, you should align the finder during the day when it is easier to locate objects.
To align the finder:
1. Choose a conspicuous object that is over 500 yards away. This will eliminate any possible
parallax effect.
2. Point your telescope at the target and center it in the eyepiece of the telescope.
3. Check the finder to see where the object is located in the field of view.
4. Adjust the two screws on the finder bracket, until the cross hairs are centered on the target object.
Accurate alignment of the finder will make it much easier to find objects in the main optical tube.
Remember that the finderscope is a simple refracting telescope and therefore will always give an inverted
(upside-down and backwards) view. Because of this, it may take a few minutes to familiarize yourself with
the directional change each screw has on the finder.
