O. Box 1815, Santa Cruz, CA 95061 IN 034 Rev C 1099 Congratulations!Your Orion Sky Wizard Model 1 will put the fun back in your telescope observing. It provides a digital readout of celestial coordinates, a database of the more than 110 of the most interesting deep-sky subjects, and the ability to guide the observer to astronomical objects. [. . . ] You'll need to point your telescope to two known stars, tell Sky Wizard which ones they are, and you're ready to go. Pick a bright known star from the list and center it in the telescope's eyepiece. Scroll through the star list to find the name of the star centered in the eyepiece, then press ENTER. Choose another bright star for the second alignment star and repeat step 3. After Sky Wizard determines the transformation resulting from star alignment, it displays a measure of how well the alignment agrees with its star data. This "warp factor" is 0. 0 for perfect alignment, but an acceptable range is ±0. 8. Only consider the warp factor after the second alignment star is entered. If the warp factor is greater than 0. 8, check to be sure you have correctly identified the setup stars and repeat the setup operation. Never assume, for example that the mechanical setting circles are exact for the DEC=0 index mark. Always double check the accuracy of the index mark, especially on your first night out. If the warps are larger than 10, check the encoder polarity and encoder ratios. Always do the ENC TEST (Encoder Direction Test) after installing the Sky wizard, before you go out at night for the first time. vertical. 5) RA DEC Displays right ascension and declination, providing a continuous display of telescope position. This example shows a right ascension of 7 hours and 42 minutes, and a declination of north 28. 1 degrees. (Note that the final digit in the declination is in tenths of a degree. ) CATALOG This mode retrieves information from one of Sky Wizard's six separate catalogs. Select this mode by pressing MODE, then either UP or DOWN until CATALOG is displayed, then press ENTER. Press the UP or DOWN arrows to select one of the catalogs, then press ENTER when the catalog you prefer is displayed. Catalogs available (and typical display): Star catalog: Messier catalog: Planets catalog: ST001 M001 PLANETS The first time a catalog is used, the display will show its first entry. For example, the Messier catalog displays M001, which happens to be the Crab Nebula. First look up the object, select CATALOG mode, choose ST, and enter the index number using the arrow buttons to set the blinking digit, pressing ENTER to advance to the next digit to be set. Press ENTER after setting the last digit and the display will show the coordinates. Example CATALOG display for selecting an object from the star (ST) list: Enter number: Coordinates: Description: ST27 0513+028 MAG=4. 5 SIZE=7. 0 RHO ORION COLORED DOUBLE STAR The MESSIER catalog contains the full historical list of 110 objects cataloged by the famous French astronomer Charles Messier. These objects are the most popular objects observed by amateur astronomers. [. . . ] The encoder direction test also tells you if the encoders are hooked up backwards. If the encoder test goes the wrong way, simply go to INSTALL mode and change the polarity of the axis question. Be sure to turn off the unit, then back on before doing the encoder test again. If you have a German equatorial mount, is your first star in SETUP mode in the Eastern part of the sky? [. . . ]
