Page 6: Telescope Setup
Getting Started Set-up: Place the telescope on the table provided. Remove the dust caps (13) from the eyepiece (1) and the telescope tube (3). This is a “push-to” telescope, meaning that the user manually points the telescope at the desired target. The telescope moves on two axes: altitude (up/down) and azimuth (left/right). -
Page 7: Focusing
How to Focus: Try out the telescope during the day when you can see what you’re doing. Aim the telescope in the general direction of an object on land (not the Sun) at least ¼ mile away. Look through the eyepiece (1) and slowly rotate either of the two focus wheels (10) until the object comes into sharp focus. -
Page 8: Using The Zoom Lens
How to Zoom: The “power” or “magnification” of a given telescope depends upon the eyepiece you use. This telescope has a “zoom” eyepiece, meaning that you can change the magnification simply by twisting the eyepiece barrel (12). Always begin by using the lowest power setting to locate and center an object (turn the body of the eyepiece so that the pointer is at “21”). - Page 9 If you find it awkward to put your eye up to the eyepiece, you can rotate the telescope tube by loosening the knob on the tube clamp (4) and rotating the telescope tube (3) until the eyepiece and focuser are in a more convenient position for your eyes.

Page 10: Using The Ez Finder
Locating Objects using the EZ Finder A “finder scope” helps you point the scope, rather like a rifle sight. The EZ Finder (2) works by projecting a tiny red dot onto a screen mounted in the front of the unit, so that when you look through the screen, the red dot will appear to float in space. - Page 11 Adjusting the EZ Finder: This should rarely be necessary if the telescope is handled gently. Checking the alignment of the EZ Finder is easiest during daylight. Aim the telescope at a distant object, such as the top of a telephone pole or chimney and center it in the telescope’s eyepiece.

Page 12: Transporting
Transporting the Telescope To carry the telescope, simply grab the carrying handle (7) while placing your other forearm under the telescope tube to provide support. When transporting the telescope in a car, place the scope on a seat and use a seatbelt to secure it. -
Page 13: Observation Guide
When and where to observe Before you head out in the dark be sure to have everything you will need. #Plan for what to observe #Know where objects are in the sky #Telescope #Black accessory bag #Table #Be sure weather conditions are suitable Note: Please do not use SVO equipment in rain, snow or windy conditions Letting the telescope cool down outside for 20 minutes... - Page 14 Where: Southern Utah is famous for its dark night skies. But, if your home is surrounded by bright lights, you might need to drive a little bit to find them. For example, Dark skies are not required if you just want to look at the moon or planets, but important for most other celestial objects.

Page 15: Keeping Equipment Clean
Observing the Moon: When viewing the moon, it can be too bright, temporarily destroying your night vision as well as washing out the details of the moon’s surface. To correct this, you can use the moon filter (14) by putting the telescope tube cover in place and sliding the filter aside to allow the correct amount of light into the telescope. -

One more time: WARNING: Never look directly at the Sun through a telescope— even for an instant — as permanent eye damage will result. Do not point the telescope at the Sun, as parts will melt! Children should use this telescope only with adult supervision.
