page 10 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 orR.A. lock ( 26, Fig. 2b and Fig. 9a ). When this axis is unlocked, the telescope pivot...

page 11 NEVER point the telescope directly at or near the Sun at any time!Observing the Sun, even for the smallest fraction of a second, willresult in instant and irreversible eye damage, as well as physicaldamage to the telescope itself. 5.

If you have just completed Lesson 5, Starfinder's display now ...

page 17 Initializing Starfinder This exercise describes how to initialize Starfinder. Initialization is a procedure that enables Starfinder to operate correctly. When you firstuse Starfinder, it doesn't yet "know" the location of the observing site or the time ordate of the observation sessi...

page 18 7. Starfinder then prompts you to enter the status of Daylight Savings Time. Press one of the Scroll keys to toggle between the YES/NO settings. Select the desiredsetting by pressing ENTER. NOTE: Daylight Savings Time may be referred to by a different name in various areas of the world. 8. I...

page 19 Training the Drive Next, train the drive using Starfinder. Perform this procedure the first time you useStarfinder with your telescope, after a Reset, or if you are experiencing any pointingaccuracy problems. Training the drive gives your telescope a higher degree of point-ing accuracy. NOTE...

page 20 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 toalign your telescope using One-Star (Polar) Alignment. An alternate m...

page 21 Which One’s the Alignment Star? If Starfinder has chosen an alignment star that you are unfamiliar with, how can yoube sure if the star in your eyepiece is really the alignment star? The rule of thumb is that an alignment star is usually the brightest star in that area ofthe sky. When you vi...

page 22 You have now completed all the Lessons for the basic operation of your 4504telescope. All of Starfinder's features perform in the same way as the featurescovered in Part 1. Practice these procedures so you can apply them to themore advanced Starfinder menu features presented in Part 2 of thi...

page 23 PART TWO : Starfinder Controls and Menus This section describes how Starfinder operates, including: • Starfinder's controls • How to move through Starfinder's menus • Alignment setups • Starfinder's Menus Control of the 4504 is through the operation of the standard-equipment Starfinderhandbo...

page 25 Speed/? Key: Briefly pressing the Speed/? key cycles through the seven slew speeds that move the telescope (see “Slew Speeds,” page 14). NOTE: Pressing the Speed/? key briefly changes the slew speed. Holding down the Speed/? key longer (one to two seconds) accesses the Helpfunction. The Spee...

page 26 How Starfinder's Menus Work It is important to understand that Starfinder's menu selections are set in a loop. Thismeans that pressing the Scroll Down key cycles down through all the available optionswithin a given category and then returns to the first option. The Scroll Up key cyclesup thr...

page 27 NOTE: To perform an accurate calculation, Starfinder must be properly initialized with the current date, time, and location of the observing site. To enter the current date, time, and location information of your observingsite, see “ INITIALIZE STARFINDER” page 17, before proceeding with thi...

page 28 Starfinder Menus Object Menu Almost all observing with Starfinder is performed using the Object menu. ( Note: Exceptions include Guided Tour and Landmark Survey. ) See “GO TO SATURN,” page 20, for an example of observing using the Object menu. Also see “USING THEGUIDED TOUR,” page 21. Many S...
