INTRODUCTION
This manual details the set-up, operation, specifications and optional accessories of the Meade Model
226W 2.4" (60mm) Altazimuth Refracting Telescope. The Model 226W is an easy to operate, high
performance telescope designed for both astronomical and terrestrial observing. In order that you may
achieve maximum utilization of the instalment, we urge that you take a few minutes to read all of this
manual before making first observations through the telescope. As you read through this manual, the
technical terms associated with telescopes will be made clear.
STANDARD
EQUIPMENT:
(Refer
to Fig. 1)

Diagonal mirror (.965" O.D.)
5x24mm viewfinder with bracket
Altazimuth mount with altitude slow-motion control.
Hardware package: 3 bolts (3" long) with wing nuts and washers
3 screws
(1/2" long)
with wing nuts
All other necessary hardware provided in place.
UNPACKING AND ASSEMBLY (Note: Numbers in () refer to Fig. 1)
Note that although the telescope is unassembled, all of the more difficult or complicated sections of the
instrument are already factory pre-assembled; first time assembly of the telescope should not require
more than about 15 minutes. To set up the telescope, follow this procedure:
1. Remove and identify the telescope's components, using the listing above.
2. The optical tube may need to be adjusted to a more horizontal position for easier assembly: loosen the
altitude lock knob (17) and reposition the optical tube so as to provide easy access to the mount for
attachment of the tripod legs (7).
3. Attach the 3 hardwood tripod legs (7) to the base of the altazimuth mount (10) with the 3 hinged
accessory tray supports (8) facing inward. Three bolts (11), each about 3" long, with washers and wing
nuts, are provided for this purpose at the end of the legs that attach to the mount.
4. Attach the accessory tray (9) to the tray supports with the short screws and wing nuts provided.
5. Adjust the sliding tripod legs to the desired height by loosening the thumb screw at the bottom of the
unextended leg; then reposition the sliding center portion of the leg to desired height and firmly retighten
the thumb screw to secure the leg(s).
6. Attach the viewfinder bracket (2) to the telescope using the 2 thumbscrews provided. (During shipment,
these thumbscrews may be pre-threaded into the main telescope tube at the viewfinder location). The
thumbscrews fit through 2 holes located at the base of the viewfinder bracket and thread into the main
tube.
7. insert the diagonal prism (13) into the focuser drawtube (15) and the Ke25mm eyepiece (1) into the
diagonal mirror. Secure each in place with a moderate tightening of the respective thumbscrews. It is the
eyepiece that determines the power at which the telescope is operating. Higher or lower power
eyepieces are available to suit particular observing situations. The Ke25mm eyepiece, included as
standard equipment, yields 28 power (written as 28X) with the Model 226W.
8. The telescope is now completely assembled. To move the telescope and point it from one object to
another, first slightly loosen one of the chrome-look (star shaped) knobs (5) which serves as a vertical
lock, as well as the azimuth (horizonal) lock (6). Also loosen the altitude coarse adjustment lock knob
(17). Loosening these locks allows the telescope to be turned freely (vertically and/or horizontally) in any
direction so that the telescope can be moved to locate and point at an object. Once a sky object is found
the altitude coarse adjustment lock knob (17) can be tightened and the altitude slow motion fine
adjustment control knob (16) can then be used to effect very smooth and accurate tracking in the vertical
axis.
