WARNING ® NEVER USE A MEADE 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. How This Manual is Organized This manual is di

How to Assemble Your Telescope The giftbox contains the optical tube assembly and the tripod with the equatorial Leg lock knob mount. The accessories are located within compartments custom-cut into the styro- foam block inserts. Refer to Figures 1, 2a, 2b, and 2c for images of the parts and the Threaded overall assembly of the 4504 telescope. hole 1. Remove the components from the giftbox: Remove and identify the telescope’s Sliding standard equipment. For a listing of parts that are included i

8. Tilt the assembly: Unlock the R.A. lock (26, Fig. 2b) and the Dec lock (27, Fig. 2b) so that the telescope turns freely on both axes. Tilting these axes makes it 1 2 1 easier for you to perform the following steps. Turn the latitude adjustment knob 3 (16, Fig. 2a) until approximately 1 1/2 inches of thread is showing. This will adjust the equatorial mount (1, Fig. 2a) to a comfortable angle for tube attachment. 9. Attach the cradle rings to the saddle plate: Remove the attachment screws fro

LESSON 2: Balancing the Telescope In order for the telescope to be stable on the tripod and also for it to move smoothly, it must be balanced. To balance the telescope, you will unlock the Right Ascension or R.A. lock (26, Fig. 2b and Fig. 9a). When this axis is unlocked, the telescope pivots Dec more or less horizontally on the mount. This is called the R.A. axis. Later in the pro- Lock cedure, you will also unlock the Declination or Dec lock (27, Fig. 2b and Fig. 9a). When unlocked, the teles

NEVER point the telescope directly at or near the Sun at any time! Observing the Sun, even for the smallest fraction of a second, will result in instant and irreversible eye damage, as well as physical damage to the telescope itself. 5. Check this alignment on a celestial object, such as a bright star or the Moon, and make any necessary refinements, using the method outlined above in steps 3 and 4. With this alignment performed, objects first located in the wide-field viewfinder will also be ce

Observe the World Around You Practice observing during the day, when it is easier to become familiar with the con- trols of your telescope. 1. Loosen the telescope’s R.A. lock (26, Fig. 2b) and Dec lock (27, Fig. 2b). 2. Move your telescope to observe distant street signs, mountains, trees, and other structures. Use your viewfinder to to help site-in an object. 3. When the object is centered in the viewfinder’s crosshairs, remember to re-tighten the R.A. and Dec locks. 4. Center the object in

Speed 1: Fastest speed to move the telescope from one point in the sky to another. Speeds 2 or 3: Best used for the rough centering of an object in the eyepiece. Speeds 4 or 5: Enables the centering an object in the field of a low-to-moderate power eyepiece such as the standard H 25mm Speeds 6 or 7: Best used for the fine centering of an object in the field of view of a high-power eyepiece such as the standard SR 4mm.

Observe a Star using the Automatic Tracking Feature In this example, Starfinder's Arrow keys are used to find a star, and then Starfinder's tracking capability automatically keeps the star centered in your telescope's eyepiece. 1. If you have just completed Lesson 5, Starfinder's display now reads "Align: One Star." Go to Step 2. If you have not used Starfinder yet or have just plugged it into the HBX port, perform the procedure described in "ACTIVATE THE ARROW KEYS," page 14. Then go to Step 2

Initializing Starfinder This exercise describes how to initialize Starfinder. Initialization is a procedure that enables Starfinder to operate correctly. When you first use Starfinder, it doesn't yet "know" the location of the observing site or the time or date of the observation session. During the Initialization procedure, you will enter this information. Starfinder then uses the information to calculate the location of celestial objects (such as stars and planets) and to move your telescope

Select the desired setting by pressing ENTER. NOTE: Daylight Savings Time may be referred to by a different name in various areas of the world. 8. If you have previously entered the Country/State and City of your observing site (as described in "ACTIVATE THE ARROW KEYS," page 14), go to step 9. If you have not enter

> Training the Drive Next, train the drive using Starfinder. Perform this procedure the first time you use Starfinder with your telescope, after a Reset, or if you are experiencing any pointing accuracy problems. Training the drive gives your telescope a higher degree of point- ing accuracy. NOTE: Use a terrestrial object, such as a telephone pole or lamp post, to train the drive. It is best to perform this procedure during the daytime. Complete this exercise once every 3 to 6 months to maintain

Align Your Telescope Using Starfinder After completing the "Train the Drive" procedure, align your telescope using Starfinder. The fastest and easiest way to start observing with Starfinder's Go To capabilities is to align your telescope using One-Star (Polar) Alignment. An alternate method, Two-Star alignment, is described later in this manual. 1. With "Train Drive: Dec Train" displayed (or scroll to this menu, if necessary), keep pressing MODE until "Select Item: Setup" is displayed. Press EN
