Meade® Infinity 50™ 50mm (2”) Alt-azimuth Refracting Telescope Instructional Manual (800) 626-3233 www.meade.com 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.
WARNING Never use the telescope to look at the Sun! Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late. Do not point the telescope or its viewfinder at or near the Sun. Do not look through the telescope or its viewfinder as it is moving. Children should always have adult supervision while observing.

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.
To move the telescope on the mount, slightly loosen the mount locking knob (14, Fig. 1). Move the telescope in altitude and/or azimuth to the desired target. When finished, tighten the mount lock knob (14, Fig. 1). Tip: By keeping the mount lock knob slightly tight, the telescope can still be moved in altitude without running the risk of having the telescope “flip” in the up or down movement. VIEWFINDER FOCUSING AND ALIGNMENT The 5 x 24mm viewfinder (2, Fig.
6. Avoid setting up the telescope inside a room and observing through a closed window pane. Images may appear blurred or distorted due to temperature differences between inside and outside air. Also, it is a good idea to allow your telescope a chance to reach the ambient (surrounding) outside temperature before starting an observing session. 7.
To use the 2x Barlow lens, remove the diagonal mirror from the eyepiece holder (17, Fig. 1). Insert the 2x Barlow lens and secure with the thumbscrew. Next insert the diagonal mirror(15, Fig.1) and eyepiece (1, Fig. 1). Refocus until the image is sharp. A FEW WORDS ABOUT POWER The useful higher magnification with any 50mm diameter telescope is in the range of 50 to 100 power.
