2 W ARNING: Never look at the sun with your telescope (or even with just y our ey es) without a pr ofessionally made solar filter . Permanent ey e damage or blindness could result. Y oung c hildren should use this telescope only with adult supervision.
3 the telescope determines the magnifying power . Magnification is discussed in more detail in the Using Y our T elescope section. 2 EZ Finder II reflex sight: This is a special “finder” that helps you aim the telescope and locate objects in the sky f or viewing.
4 then a flat washer onto each of the sock et-head cap screws. Attach one of the two tube rings (5) to the base bracket (18) with a washer-equipped screw using the included hex key (19) (Figure 3). Rotate the base brack et 180° so the remaining attachment hole is accessible .
5 Altitude and Azimuth (Aiming the T elescope) The StarBlast 6 altazimuth base (9) per mits motion along two axes: altitude (up/down) and azimuth (left/r ight). See Figure 5. Moving the telescope up/down and left/r ight is the “natural” wa y people aim objects, which makes pointing the telescope intuitive and easy .
6 skies and a br ight setting is used under light-polluted skies or in da ylight. At t he end of your obs ervin g session , be sure to tur n the power knob counterclockwise until it clicks off . When the two white dots on the EZ Finder II’ s rail and power knob are lined up , the EZ Finder II is turned off.
7 a star is - the br ighter a star is, the lower its magnitude will be. A good star to remember for this is Megrez (mag. 3.4), which is the star in the “Big Dipper” connecting the handle to the “dipper” (Figure 8).
8 T o calculate the magnification of a telescope-eyepiece com- bination, simply divide the focal length of the telescope by the f ocal length of the ey epiece.
9 C. The Planets The planets don’t stay put like the stars, so to find them yo u s ho u ld re fer t o “T h is Mo n th ’ s S ky S u mm ar y ” in t he Learning Center section of our website (telescope.com). V enus , Jupiter , and Satur n are the brightest objects in the sky after the Sun and the Moon.
10 Appendix A: Collimating (Aligning the Mirr ors) Collimating is the process of adjusting the mirrors so they are aligned with one another . Y our telescope’ s optics were aligned at the factory , and should not need much adjust - ment unless the telescope is handled roughly .
11 Now tighten the three small alignment screws equally to secure the secondar y mirror in that position. If the entire primar y mirror reflection is not visible in the sec- ondar y mirror, as in Figure 10c; you will need to adjust the tilt of the secondar y mirror .
12 Star-T esting the T elescope When it is dark, point the telescope at a bright star and accu- rately center it in the ey epiece’ s field of view . Slowly de-focus the image with the focusing knob . If the telescope is correctly collimated, the e xpanding disk should be a perfect circle (Figure 15).
