Congratulations on your purchase of an Orion SkyQuest XTi IntelliScope Dobsonian. It is a high-perfor- mance astronomical instrument designed to provide dazzling views of celestial objects and unprecedent- ed ease of use. With the addition of the optional IntelliScope Computerized Object Locator (Controller), you gain the ability to locate and view thousands of celestial objects with the push of a button. -

Page 12: Focusing The Telescope
Focusing the telescope With the 25mm Sirius Plössl eyepiece in the focuser and secured with the thumbscrew(s), move the telescope so the front (open) end is pointing in the general direction of an object at least 1/4-mile away. Now, with your fingers, slowly rotate one of the focusing knobs until the object comes into sharp focus. - Page 13 of focus, you will need to refocus the finder scope for your The magnification provided by the 10mm eyepiece is: vision.

- Page 14 Figure 17. Picking up and carrying the SkyQuest IntelliScope as a single unit (with tube held captive on the base) requires some caution. First, position the tube vertically. Then grasp the handle on the base with one hand while supporting the tube with the other. This ensures that the tube will not swing down and impact the ground With knees bent, slowly lift the base while supporting the tube.

It is a good idea to check the collimation of your tele- collimation cap or other, more sophisticated collimation devic- scope before each observing session and make any neces- es such as the Orion LaserMate Deluxe laser collimator. The sary adjustments. center ring should never be removed from the primary mirror! To check collimation, remove the eyepiece and look down the focuser drawtube. -

Preparing the telescope for collimation Figure 20. The SkyQuest Once you get the hang of collimation, you will be able to do XTi IntelliScope it quickly even in the dark. When trying it for the first time or properly set up two, though, it is best to collimate in daylight, preferably in a for collimation. -

If turning that one thumbscrew does not seem to be bringing you closer to collimation, try using one of the other collimation thumb- screws. - Page 18 SkyQuest XT8i, XT10i and XT12i models are designed to center the object.
