OBSERVING Choosing an Eyepiece A telescope’ s eyepiece magnifies the image f or med by the telescope’ s main optics. Each ey epiece has a focal length, e xpressed in millimeters, or “mm. ” The smaller the f ocal length, the higher the magnification.
20 Sync On Preset men u if y ou do not park y our telescope (this men u will reset all your f ocus presets after you turn off and tur n on your scope again ).
Y ou can also obser v e stars and objects in the night sky using this method, but note that objects begin to slowly drift across the ey epiece field. This motion is caused by the rotation of the Ear th.
22 Speeds 4, 5, or 6: Enab le center ing of an object in the field of a low-to-moder ate po wer e yepiece, such as the standard UltraWide 24mm. Speeds 7 or 8: Best used f or rough centering of an object in the viewfinder . Speed 9: Mo v es the telescope quickly from one point in the sky to another .

24 When the procedure is perf ormed correctly , "Alignment Successful" displa ys. If A utostar II does not displa y this message, perf or m this procedure again. Note: Alignment stars ma y change from night to night. All that is required is f or the obser v er to center the selected stars in the ey epiece when prompted.
5. Press MODE to return to the T our list. Press the Scroll keys to scroll through the list. Press ENTER when you find the next object y ou wish to obser ve . 6. Press and hold down MODE f or two seconds to leav e the Guided T our menu. Other Guided T ours are av ailable, such as "Ho w F ar is F ar" and "A Star's Life.
26 It is impor tant to understand that menu selections are set in a loop ( Fig. 28 ). This means that pressing the Scroll Down k ey ( 7, Fig. 2 ) cycles down through all the a v ailable options within a given categor y , then retur ns to the first option.
4. Press the Scroll Down k ey once to displa y the "Sunset" option in the Event menu. 5. Press the ENTER ke y to choose the "Sunset" option and move do wn another le vel. 6. A utostar II calculates the Sunset time based on the current date, time , and loca- tion.

34 J Calibrate Sensor s: This men u allo ws you to improv e your telescope's pointing accuracy to alignment stars. It calibrates to correct slight mechanical misalign- ment due to transpor t, vibration, or aging. It is recommended that calibration be perf ormed once on a new telescope after the user initially assembles it.

48 OPTIONAL ACCESSORIES A wide assor tment of professional Meade accessories is a vailab le for the RCX400 tel- escope models. The premium quality of these accessories is well-suited to the quality of the instr ument itself. Consult the Meade General Catalog f or complete details on these and other accessories.
Series 4000 Nebular Filter s: A moder n boon to the city-dwelling deep-space obser v er , the interference neb ular filter eff ectiv ely cancels out the effects of most urban light pollution, while leaving the light of deep-space neb ular emissions vir tual- ly unattenuated.
50 #1220 Field De-r otater: The field de-rotater attaches to the rear cell of the telescope and plugs into an RS232 (Serial) por t. Digital data f ed from the telescope's micro- processor to the field de-rotater permit precise and continuous update of the de-rota- tion required to maintain pinpoint star images throughout the field.
MAINTENANCE RCX400 telescopes are precision optical instruments designed to yield a lifetime of rew arding applications. Given the care and respect due any precision instrument, your RCX400 will rarely , if e ver , require f actor y ser vicing. Maintenance guidelines include: a.
r ings; these are called diffraction rings. Focus until the diffraction rings fills about 10% of the ey epiece field-diameter. If the dar k central spot is offset in (i.e ., not concentric with) the diffr action rings, y our telescope’ s optical system is misaligned and requires collimation.
