Observing (Visual) Use
Warning Note: Never look directly at the Sun with the naked eye or with your spotting scope. Permanent eye damage
may result.
Remove the lens cap protecting the front objective lens of the spotting scope – see Figure 1.
Eyecup Setting
The zoom eyepiece has a twist-up type Eyecup. If you wear
eyeglasses, the eyecup should be all the way down (turn
counterclockwise) as this will allow you to see the full field of
view. If you do not wear eyeglasses, normally the eyecup
should be all the way up (turn clockwise). You can also use the
eyecup at any position between the full up or down position if
it is more comfortable for you.
Changing the Magnification (Power)
You can change the power by turning the Knurled Ring in either direction. The power will be shown on the indicator where it
is lined up with the white line. You will have to refocus after changing the power. Remember that the brightest views with the
widest field of view will always be at the lowest power.
Focusing
Your spotting scope has a dual focus knob system. Once you reach
focus with the large (coarse) focus knob, then you can use the fine
focus knob (small one) to achieve a very sharp image. Rotate the
coarse focus knob until the image in the eyepiece is clear and sharp.
You will have to refocus when changing power. Once you are
focused clearly on an object, turn the focus knob clockwise to focus
on a closer object and counterclockwise for a more distant object.
Viewing Position
The normal position for the spotting scope is shown in Figure 1. You may rotate the spotting scope to any position in a range
of about 180° if it is more convenient for you. You rotate the spotting scope by unlocking the Position Lock Knob and turning
it clockwise. Then, rotate the spotting scope to the position you desire and then lock the position lock knob.
Sight Guide Line and the Lens Shade
You can use the Sight Guide Line (located on the Lens Shade) to aid you in locating your object. It may
be difficult to use in the normal position of the spotting scope. It may be easier to use if you rotate the
viewing position slightly to enable better viewing with the sight line guide.
The Lens Shade pulls out and is useful to block unwanted glare and other reflections that can spoil your
view and/or image.

Optional Eyepieces
Your spotting scope was designed so that you could use optional 1.25" eyepieces. These type eyepieces are available from
Celestron as well as from several other manufacturers. Extra eyepieces will allow usage of higher powers, wider fields of
view, and other factors. These type eyepieces will attach similar to how the zoom eyepiece is attached.
