3 StarBlast par ts: 17mm Explorer II eyepiece The ey epiece is the par t of the telescope that you actu- ally look through to see things. The f ocal length of the ey epiece and the telescope determines the magnifying power . Magnification is discussed in more detail in the Using Y our T elescope section.

5 Focusing the T elescope With the 17mm Kellner e yepiece (1) inserted into the focuser (4) and secured with the thumbscrews , aim the opti- cal tube (3) so the front (open) end is pointing in the general direction of an object at least 1/4-mile aw ay .

8 piece, if y ou wish. This is recommended for small and bright objects, lik e planets and double stars . The Moon also takes higher magnifications well. The best rule of thumb with eyepiece selection is to start with a low po wer , wide-field eyepiece , and then work your wa y up in magnification.
9 sometimes it is visible to the nak ed ey e during full daylight! Ironically , V enus appears as a thin crescent, not a full disk, when at its peak brightness. Because it is so close to the Sun, it ne ver w anders too far from the morning or ev ening hor izon.
10 Aligning the Secondary Mirror With the collimation cap in place, look through the hole in the cap at the secondar y (diagonal) mirror . Ignore the reflections f or the time being. The secondar y mirror itself should be cen- tered in the f ocuser drawtube , in the direction parallel to the length of the telescope.
11 Aligning the Primary Mirror The final adjustment is made to the primar y mirror . It will need adjustment if , as in Figure 10d, the secondar y mirror is cen- tered under the f ocuser and the refle.
