WHAT'S IN THE BOX

We recommend saving your telescope box so it can be used to store the telescope when it is not in use. Unpack the box carefully as some parts are
small. Use the parts list below to verify that all parts and accessories are present.

SOLAR WARNING
•
Never look directly at the Sun with the naked eye or with a telescope unless you have the proper solar filter. Permanent and irreversible eye damage may result.
•
Never use your telescope to project an image of the Sun onto any surface. Internal heat build-up can damage the telescope and any accessories attached to it.
• Never use an eyepiece solar filter or a Herschel wedge. Internal heat build-up inside the telescope can cause these devices to crack or break, allowing unfiltered sunlight to pass
through to the eye.
• Do not leave the telescope unsupervised, especially when children or adults unfamiliar with the correct operating procedures of your telescope are present.

INSTALLING THE FINDERSCOPE

1. Loosen the two finderscope adjustment screws so they don't protrude
into the bracket.
2. Slide the rubber O-ring over the eyepiece end of the finderscope and
roll it 2/3 of the way up until it sits in the groove in the finderscope body.
3. Insert the eyepiece end of the finderscope through the narrow part of
the bracket until the O-ring presses tightly between the finder and the
inside of the bracket. Once it stops, then pull outward on the spring
loaded adjustment screw and continue inserting the finderscope until it
is approximately centered in the bracket.
4. Tighten the two adjustment screws until they make contact with the
finderscope body.
5. Locate the finderscope dovetail mounting bracket on the top left side
of the telescope's rear cell and loosen the set screw until it is not
protruding into the dovetail receptacle.
6. Slide the finderscope and bracket all the way into the dovetail mounting
bracket on the telescope and tighten the set screw on the mounting
bracket to hold the finderscope in place.
INSTALLING THE VISUAL BACK
The visual back is an accessory that adapts the telescope to accept 2"
visual accessories. To install the visual back:
1. Remove the cap on the telescope's rear cell and thread the knurled
slip ring on the visual back over the threads on the rear cell.
2. Hold the body of the visual back with the set screw in your desired
position and rotate the knurled slip ring clockwise until it is tight.
3. If you want to remove the visual back, rotate the slip ring counterclockwise
until it is free of the rear cell.
