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.

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.

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.
