Congratulations on y our purchase of the Orion IntelliScope ™ Com- puterized Object Locator . When used with any of the SkyQuest IntelliScope XT Dobsonians, the object locator (controller) will pro- vide quick, easy access to thousands of celestial objects f or vie w- ing with your telescope . The controller’ s user-friendly keypad combined wit[...]

Par ts List Y our IntelliScope ™ Computerized Object Locator comes with the f ollowing par ts: Qty . Description 1 Object locator computer (controller) 1 Altitude encoder assembly 1 Coil cable 1 Altitude encoder cable (53" long) 1 Azimuth encoder cab le (24" long) 6 Wire retaining clips 2 Hook-and-loop strips (1 “hook” str ip, 1 “[...]

Mak e cer tain the location of the strip on the base will not cause the controller to interf ere with the motions of the mount. Y ou may want to consider using the optional holster instead of the supplied hook-and-loop strips. The holster is a metal holder cus- to[...]

Ne xt, place the nylon spacer , the 1/16"-thic k washer , and the 1/32"-thick w asher on the vertical stop screw , and thread the entire assembly into the insert in the base’ s front brace. Now , rotate the telescope upw ards in altitude until the mirror cell of the telescope comes into contact with the vertical stop. Place the car pent[...]

mov e the telescope until y ou hav e centered the star on the crosshairs of the finder scope . Look into the ey epiece of the telescope, and y ou should see the alignment star in the field of view of the e yepiece. If it isn’t, then y our finder scope is out of alignment with your tel- escope and will need to be adjusted. Once the alignment st[...]

If you are standing to the left of the telescope and f acing the same direction the telescope is pointed, the guide arrows will e xactly corre- spond with the direction you should mo ve the telescope (Figure 9). Otherwise ,[...]

It is easiest to mov e the telescope in one direction at a time (say altitude) until the corre- sponding number reached “0.0”. Then mov e the scope in the other direction (azimuth) until that number also reads “0.0”. If the object selected to view is currently located belo w the horizon, the w ord “HORIZON” will flash bef ore the guide[...]

During close approaches you’ll see a red disk, possib ly some light and dark regions, and ma ybe the polar ice cap . T o see surface detail on Mars , you will need a high power[...]

The object’ s catalog designation will be shown in the upper left corner of the display screen, with the guide arrows in the upper right. The lower left will displa y the constella- tion the object resides in and the object’ s common name (if it has one) or a brief descr ip- tion of the object.

Locating Star Clusters Star clusters are just what their name implies; groupings of stars. Star clusters come in two main types, open and glob ular . Open star clusters reside within our Milky Wa y galaxy and usually[...]

7. Locating Stars The IntelliScope database contains 837 stars. Stars alw a ys appear like tiny points of light. Even po werful telescopes cannot magnify a star to appear as more than a point of light! Y ou can, howe ver , enjo y the different colors of the stars and locate many pretty doub le and multiple stars. Y ou can also monitor variab le sta[...]

the “S=” refers to the separ ation between the two brightest stars. The “M=” now ref ers to the magnitude of the brightest star .) T o go to the ne xt double star in the selected con- stellation, simply press the up arrow b utton. The guide arrows will now direct y ou to the ne xt double star in the constellation. If there are no more doubl[...]

The object’ s ST catalog designation will be shown in the upper left corner of the LCD screen, with the guide arrows in the upper right. The lo wer left will show the constellation the object resides in and the star’ s name. Y ou can get more inf ormation on the star selected by pressing the Enter button. The second line of the LCD screen will [...]

Using the ID Button When you locate an object and center it in the e yepiece, y ou can identify it by simply pressing the ID button. The LCD screen will display “IDENTIFY” with the word “ANY” flashing. Y ou can then use the up/and down arrow b uttons to scroll through sev eral more specific options (“ST AR”, “DOUBLE”, “CLUSTER?[...]

of the Dec. coordinate will be flashing. Use the arrow buttons to select “+” or “-”f or the Dec. coordinate. Then, the first two digits of the Dec. coordinate will begin flashing. Press the two numerical buttons that correspond to the deg rees value of the Dec. coordinate. Then the tenth of a degree v alue for the Dec coordinate will beg[...]

This can happen if the alignment stars initially chosen during setup are somewhat close to each other (less than 60˚ apar t) or if the area of sky being view ed is a considerab le distance aw ay from the alignment stars chosen. T o improve pointing accur acy in a specific area of the sky , select an object in the locator’ s database from that r[...]

If you mo ve the telescope counter-clockwise in azimuth, the n umber in the lower right should increase, while if y ou move cloc kwise in azim uth, the number will decrease. If yo[...]
