6 5. Using Y our T elescope Focusing the T elescope With the 25mm e yepiece inser ted in the focuser , mov e the telescope so the front (open) end is pointing in the general direction of an object at least 1/4-mile awa y . Now , with y our fingers, slowly rotate one of the f ocusing knobs until the object comes into shar p focus .
7 The SkyView Pro 8 EQ has a focal length of 1000mm, which when used with the supplied 25mm ey epiece yields: 1000mm = 40x 25mm The magnification provided b y the 10mm eyepiece is: 1000mm = 100x 10mm The maximum attainable magnification for a telescope is directly related to how much light it can gather .
8 star Sigma Octantis lies about 1° from the SCP , but it is barely visible with the nak ed eye (magnitude 5.5). F or general visual obser v ation, an appro ximate polar align - ment is sufficient. 1. Lev e l the e quator ial m ount by ad justi ng the l ength of the three tripod legs.
9 The reticle of the polar axis finder scope has a tiny star map printed on it that makes precise polar alignment quick and easy . If you do not hav e a clear view of P olaris from your obser ving site, you will not be ab le to use the polar-axis finder to precisely polar align the telescope .

Most setting circles are not accurate enough to put an object dead-center in the telescope’ s eyepiece , but they should place the object some where within the field of view of the find- er scope, assuming the equatorial mount is accurately polar aligned.
T o check collimation, remo ve the eyepiece and look down the f ocuser drawtube . Y ou should see the secondar y mirror cen - tered in the dra wtube, as well as the reflection of the pr imary mirror c.
