INSTALLING THE FINDERSCOPE
1. Locate the finderscope (it will be mounted in the finder-
scope bracket).
2. Remove the knurled nuts on the threaded posts on the
telescope tube (Figure 12).
3. Mount the finderscope bracket by placing it over the
posts protruding from the optical tube and then holding it in
place thread on the knurled nuts and tightening them down.
4. Note that the finderscope should be oriented so that the
larger diameter lens is facing toward the front of the
telescope tube.
5. Remove the lens caps from both ends of the finderscope.

ALIGNING THE FINDERSCOPE
1. Locate a distant daytime object and center it in the low power (20 mm) eyepiece in the
main telescope.
2. Look through the finderscope (the eyepiece end of the finderscope) and take notice of the
position of the same object.
3. Without moving the main telescope, turn the adjustment thumbscrews (Figure 12) located
around the finderscope bracket until the crosshairs of the finderscope are centered on the
object chosen with the main telescope.
4. If the image through the finderscope is out of focus, rotate the eyepiece of the finderscope
for a clear view.
Note: Objects viewed through a finderscope are upside down and backwards which is
normal.

TELESCOPE BASICS
FOCUSING
To focus your SV501P turn the focus knob located near the rear of the telescope (see Figure
1). Turning the knob counterclockwise allows you to focus on an object that is farther than the
one you are currently observing.
Turning the knob clockwise from you allows you to focus on an object closer than the one
you are currently observing.
Note: Remove the front lens cap of the SV501P optical tube prior to attempting your observa-
tion.
Note: If you wear corrective lenses (specifi cally glasses), you may want to remove them
when observing with an eyepiece attached to the telescope. If you have astigmatism,
corrective lenses should be worn at all times.

TELESCOPE MAINTENANCE
While your telescope requires little maintenance, there are a few things to remember that will
ensure your telescope performs at its best.
◆
CARE AND CLEANING OF THE OPTICS
Occasionally, dust and/or moisture may build up on the objective lens of your
telescope. Special care should be taken when cleaning any instrument so as not to
damage the optics.
If dust has built up on the optics, remove it with a brush (made of camel’s hair) or a
can of pressurized air. Spray at an angle to the glass surface for approximately two
