Looking at or near the Sun will cause irreversable damage to your eye. Do not point this telescope
at or near the Sun. Do not look through the telescope as it is moving.
INTRODUCTION
Before you begin your visual journey, we urge you to take a few minutes to completely read this manual so that
you can get the best use of the equipment. This manual details the setup, operation, specifications, and optional
accessories of the Meade Infinity 50 Alt-azimuth Refracting Telescope. The Meade Infinity 50 is designed for both
astronomical and terrestrial observing. Whether you are observing objects a few meters away or light years distant,
the Meade Infinity 50’s precision optics and sturdy mount are the tools with which you can learn basic telescope skills
that can lead to a lifetime of enjoyment and discovery.

UNPACKING AND ASSEMBLY
Note that although the telescope is partially unassembled, all of the more difficult or complicated sections of the
instrument are already pre-assembled at our factory; first time assembly of the telescope should not require more
than about 10 minutes. To set up the telescope, follow this procedure:
1. Remove and identify the telescope’s components, using the Standard Equipment list shown above.
2. Spread the three tripod legs (8, Fig. 1) evenly apart and attach the accessory tray (10, Fig. 1) in the hole at the
center of the leg brace supports (9, Fig. 1) using the provided attaching screw.
3. Attach the optical tube to the mount by placing the optical tube mounting plate (12, Fig. 1) over the top of the
mount until the mounting holes line up. Place the optical-tube-to-mount lock knob (14, Fig. 1) through the
mounting holes and tighten until snug.
4. Attach the viewfinder (2, Fig. 1) and viewfinder bracket (3, Fig. 1) by un-threading the two viewfinder bracket
attaching nuts (6, Fig. 1) and placing the viewfinder bracket (with the eyepiece-end of the viewfinder facing
the focuser of the telescope) over the two protruding threaded studs. Then replace the two viewfinder bracket
attaching nuts to secure the bracket to the optical tube.
5. Insert the diagonal mirror (15, Fig. 1) into the eyepiece holder (17, Fig. 1) and the H 20mm eyepiece (1, Fig. 1)
into the diagonal mirror. Secure each in place with a moderate tightening of their respective thumbscrews (7 &
17, Fig. 1).
6. Extend the sliding leg extension (19, Fig. 1) portion of the tripod to the desired length on all three legs by opening
the tripod leg lock latch (18, Fig. 1) and extending the leg. When you achieve the desired height, lock the tripod
leg by closing the locking latch.
ALT-AZIMUTH MOUNT MOVEMENTS AND LOCK
The telescope can tilt just over 90° in altitude (the up-and-down movement) and rotate 360° in azimuth (the side-to-
side movement), hence the telescope mount is called “Alt-azimuth”. The Alt-azimuth mount can be locked only in
altitude by tightening the optical-tube-to-mount locking knob (14 Fig 1), the azimuth movement is always free.
