1 Optical tube This is the main optical component of the telescope. The glass lens at the front of the tube gathers incoming light and focuses it by bending (or refracting) the light ra ys. The tube assembly has se veral par ts built into it, which are shown and discussed in detail in the ne xt section.

7 8 Objective lens This is the main optical component of the telescope. It is an achromatic, fully coated 70mm diameter lens . 9 Glare/Dew shield This is a simple hood for the objective lens (8) that pre - vents dew formation and stra y light from hitting the lens.

9 19 Altitude lock knob This locks the telescope in the altitude (up/down) direction. K eep this knob tightened unless you are moving the telescope a significant distance in the altitude direction. F or smaller altitude adjustments, use the altitude micro- motion control rod and thumbwheel (13).
4. Assembly Assembling the telescope for the first time should take about 30 minutes. The only tools you will need are a Phillips head screwdriv er and a flat head screwdriver . As a general note, tighten all screws securely to eliminate fle xing and wobbling, but be careful not to over-tighten and thereby strip the threads.
T o mov e the telescope in the azimuth direction, loosen the azimuth loc k knob , take hold of the telescope and gently rotate it to the desired position.
Aligning the EZ Finder II When the EZ Finder II is properly aligned with the telescope, an object that is centered on the EZ Finder II’ s red dot should also appear in the center of the field of view of the telescope’s ey epiece. Alignment of the EZ Finder II is easiest dur ing day- light, bef ore obser ving at night.
tend to scatter light, which reduces an object’s brightness. T rans parency is judged by the magnitude of the faintest stars you can see with the unaided eye (6th magnitude or fainter is desirab le). If you cannot see stars of magnitude 3.5 or dimmer then con- ditions are poor .
14 T o calculate the magnification, or power , of a telescope-ey e - piece combination, simply divide the f ocal length of the tele - scope by the f ocal length of the ey epiece: T elescope Focal Leng.
15 C. The Planets The planets don’t stay put like the stars, so to find them you should refer to Sky Calendar at our website (telescope.com), or to char ts pub lished monthly in Astronomy , Sky & T ele scope, or other astronomy magazines. V enus, Mars, Jupiter , and Saturn are the brightest objects in the sky after the Sun and the Moon.
