NEVER USE YOUR TELESCOPE TO LOOK DIRECTLY AT THE SUN. PERMANENT EYE DAMAGE WILL RESULT. USE A PROPER SOLAR FILTER FIRMLY MOUNTED ON THE FRONT OF THE TELESCOPE FOR VIEWING THE SUN. WHEN OBSERVING THE SUN. PLACE A DUST CAP OVER YOUR FINDERSCOPE OR REMOVE IT TO PROTECT YOU FROM ACCIDENTAL EXPOSURE. NEVER USE AN EYEPIECE-TYPE SOLAR FILTER AND NEVER USE YOUR TELESCOPE TO PROJECT SUNLIGHT ONTO ANOTHER SURFACE, THE INTERNAL HEAT BUILD-UP WILL DAMAGE THE TELESCOPE OPTICAL ELEMENTS.

Star ~li~nrnent In order for the SynScanT" to correctly point to objects in the sky, it must first be aligned to one to three known positions (stars) in the sky. As the Earth rotates on its axis every 24 hours, astronomical objects appear to move through the sky following an arc. W~th the supplied information, the telescope can replicate a model of the sky and the movements of astronomical objects. Star alignment can be done anytime during the observing session by choosing Alignment under S

One-Star Alignment It requires only one alignment star but, without accurate polar alignment and cone error calibration (see Appendix A), it may produce lesser pointing accuracy than the other alignment methods. Refer to the HEQIEQG manual for information on how to perform accurate polar alignment. Below describes a step- by-step procedure on how to perform the One-Star Alignment: 1. Make sure the telescope has been polar aligned. 2. In the alignment screen, select I-StarAlign using the s

4. The first available selection in the Object Catalog is Recall Object. @D This is where you select previously-saved objects to view. Use the scroll keys to scroll down to "Input Coordi.>" and press ENTER. 5. The SynScanTM stores the user-defined objects in two formats- R.A/Dec and AltIAz. Press 1 for the R.A/Dec. format and 2 for the Enter RA-DEC: Alt-Azimuth format. 22h46.lm +90°00 6. By default the SynScanTM will display the R.A./Dec or AltIAz coordinates where the telescope is

PEC Training 1. Perform the accurate PolarAlignment method (see the HEQ5lEQ6 manual). 2. Slew or manually point the telescope to a star with smaller DEC coordinate. This object will be used as the guide star. 3. Activate Sidereal Tracking from the Setup Menu (see Setup Functions). Once the tracking has started, press ESC to go back to the Setup Menu. 4. Rotate the reticle eyepiece until one set of the lines becomes parallel to (or matches) the R.A. movement of the telescope (see step 2 to

TM Generally speaking the SynScan produces pointing and tracking accuracies adaquate for most applications. However, if higher precision is required, for example for astro-photography, accurate polar alignment and "cone" error calibration may be required. See the manual for HEQ51EQ6 mount for information on accurate polar alignment using the polarscope. "Cone" error is a common inaccuracy found on all German equatorial mount. It is a result from the optical axis not being aligned to the R.

6. Loosen the R.A. lock knob and rotate the telescope around the R.A. axis until the counterweight shaft is parallel to the ground. (Fig.A-2) 7. Using the Dec direction key on the hand control, adjust the telescope in Dec so Polaris sits on the R.A. lines of the reticle eyepiece (Fig.A-3). 8. Wlthout moving the R.A. axis, adjust the azimuth control knobs to bring Polaris to the center of the eyepiece (Fig.A-4). Adjustment in Dec axis using the hand control may be necessary. Place Polar

12. Carefully nudge the telescope in horizontal motion using only one finger while observing the movement of Polaris through the eyepiece (Fig.A-7). This is to determine which direction (left or right) moves Polaris closer to the center of the eyepiece. 13. Next step is to adjust the adjustment screws on the mounting plate according to your finding from step 12. If Polaris moves toward the center when the telescope is nudged toward your right hand side, You will need to loosen the adj
