Congratulations on your purchase of an Orion SkyQuest XT IntelliScope Dobsonian. It is a high-per- formance astronomical instrument designed to provide dazzling views of celestial objects and unprecedented 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 but- ton. -
Page 4: Assembly
Now that you have unpacked the boxes and familiarized your- self with all the parts in front of you, it’s time to begin assembly. The optics of the telescope are already installed in the tube, so most of the required assembly concerns the Dobsonian base. - Page 5 Do not attempt to permanently secure the bearing pads by any means as this will interfere with the motion of the telescope. 7. Place one fender washer (H) onto the azimuth axis screw (I).
- Page 6 Encoder connector board Screws Figure 6. Attaching the encoder connector board. (XT10 Shown) by adding or removing washers. This is important when using the optional IntelliScope Computerized Object Locator, since the optical tube must be exactly vertical during the two-star alignment procedure.
- Page 7 With the XT system, you can change eyepieces or add a barlow lens without hav- ing to tediously adjust the telescope’s balance as you would with other Dobsonians. The altitude friction can be made equal to the azimuth friction, ensuring optimal performance.

Page 8: Using Your Telescope
The basic assembly of your SkyQuest IntelliScope Dobsonian is now complete. It should appear as shown in Figure 1. The dust cap on the front of the telescope tube should always remain in place when the telescope is not in use. - Page 9 A good way to set the altitude tension is to point the telescope at about a 45° angle with the eyepiece and finder scope removed. Loosen the altitude tension knob until the front of the optical tube starts to drift upward.
- Page 10 Start by once again moving the telescope until it is pointed in the general direction of the object you want to see. Some observers find it convenient to sight along the tube to do this.
- Page 11 The base has a handle for easy carrying. With the retaining and tensioning knobs of the CorrecTension(XT) system hold- ing the optical tube captive on the base, the entire telescope can be carried as one unit. (This is not practical for the XT10 due to its hefty weight and size.) This requires some caution,...

When the mirrors are properly aligned, the view down the focuser drawtube should... - Page 13 The secondary mirror itself should be cen- tered in the focuser drawtube, in the direction parallel to the length of the telescope. If it isn’t, as in Figure 18b, it must be adjusted. This adjustment will rarely, if ever need to be done.
- Page 14 Star-Testing the Telescope When it is dark, point the telescope at a bright star high in the sky and center it in the eyepiece’s field of view. Slowly defo- cus the image with the focusing knob. If the telescope is correctly collimated, the expanding disk should be a perfect circle (Figure 24).

Atmospheric turbulence will worsen the effects of refraction, which can cause the image you see in your telescope to be unstable. The steadiness of the atmosphere is called “seeing.” In conditions of good “seeing,” star twinkling is minimal and objects appear steady in the eyepiece. - Page 16 B. The Sun You can change your nighttime telescope into a daytime Sun viewer by installing an optional full-aperture solar filter over the front opening of the telescope. The primary attraction is sunspots, which change shape, appearance, and location daily.

Certain photograph aids, such as the Orion SteadyPix, can help in taking photos by the afocal method. -
Page 18: Care And Maintenance
Small components like eyepieces and other accessories should be kept in a protective box or storage case. Keep the cloth dust cover on the front of the telescope when not in use. Your SkyQuest IntelliScope requires very little mechanical maintenance. The optical tube is steel and has a smooth painted finish that is fairly scratch-resistant. -
