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. \. % 'S* W ' if* Jtr w \ # Fig. 1 : The Meade Starfinder Dobsonian Telescope. Captions for Fig. 1 Contents 1. Focuser assembly 2.

Galaxies, nebulae, star clusters — in all their variations of form, color, and extent — as well as the Moon, planets, comets and other objects within the solar system, may be studied In great detail. This manual is designed for the 6“, 8", 10“, and 12.5" Starfinder Dobsonian Telescopes. With the exception of a few assembly operations and features, the four telescopes are almost identical operationally. When differences in procedures occur, they are clearly noted. Most standard and optional accessories are interchangeable between the four telescopes. For optimal enjoyment of the telescope, please take a few minutes to read this manual and become familiar with all of the Instrument's capabilities. PARTS LISTING AND ASSEMBLY When first opening the packing boxes, note carefully the following parts included with the Starfinder Dobsonian Telescope (use Figure 1 and 2 to aid In the identification process): Carton #1: The Telescope — Optical tube assembly — Primary mirror mounted in its cell — Focuser — Modified Achromat (MA) 25mm eyepiece — 5 x 24mm viewfinder — Hardware kit. CAUTION: The primary mirror must be handled with special care. Never touch its reflective surface or place the mirror where it could be damaged. Save all original packing materials; if it is ever necessary to ship the telescope, these materials will help to assure that no shipping damage will occur. Carton #2: The Mount — 2 Side boards — Front board — Ground plate — Base plate — 2 Handles — Hardware kit Assembling the Mount Assembly of your Meade Starfinder Dobsonian telescope should only take a few minutes. A phllllps screwdriver, pliers, and an adjustable wrench are the only tools you will need. 1. Attach the self-adhesive rubber feet (11, Fig. 2) to the underside of the ground plate (10, Fig. 2), the round piece with the Teflon pads. The feet should be mounted directly under the already installed Teflon pads. Two extra rubber feet have been supplied for use as “bumpers” where the telescope tube hits the front board (5, Fig 2.) at the travel limits. Place one in the center of the top ledge, and one in the center on the inside near the bottom (see Fig. 2). The exact position for these two bumpers will be obvious with the telescope mounted on the base. 2. Attach the front board (5, Fig. 2) loosely to the two side boards (4, Fig. 2) using the supplied wood screws (3, Fig. 2), and the predrilled holes. Do not fully tighten the screws yet. 3. Attach the front board/side board assembly to the base plate (7, Fig 2) using the supplied Wood Screws, and the predrilled holes. Snugly tighten all screws, including those previously installed. CAUTION: Do not overtighten the wood screws. The screws should be tightened su...
