Unpacking The entire telescope system will arrive in one box. Be careful unpacking the box. We recommend keeping all original packaging. In the event that the telescope needs to be shipped to another location, or returned to Orion for warranty repair, having the proper packaging will help ensure that your telescope will survive the journey intact. Make sure all the parts in the Part List are present. Be sure to check the box carefully, as some parts are small. If anything appears to be missing or broken, immediately call Orion Customer Support (800-676-1343) for assistance. Warning: Never look at the sun with your telescope or its finderscope—even for an instant—without a professionally made solar filter that completely covers the front of the instrument, or permanent eye damage could result. Young children should use this telescope only with adult supervision. 2. Parts List Qty.

Assembly Assembling the telescope for the first time should take about 30 minutes. You will need a Phillips head screwdriver to assemble the telescope. All screws should be tightened securely to eliminate flexing and wobbling, but be careful not to over-tighten or the threads may strip. Refer to Figure 1 during the assembly process. During assembly (and anytime, for that matter), DO NOT touch the surfaces of the telescope mirrors or the lenses of the finder scope or eyepiece with your fingers. The optical surfaces have delicate coatings on them that can easily be damaged if touched inappropriately. NEVER remove any lens assembly from its housing for any reason, or the product warranty and return policy will be voided. 1. Lay the equatorial mount on its side. Attach the tripod legs, one at a time, to the base of the mount by sliding a tripod leg attachment screw through the top of a leg and through the holes in the base of the mount. The washers should be Figure 2. The equatorial mount of the SpaceProbe 3 EQ. R.A. setting circle Latitude scale Latitude adjustment T-bolt Azimuth lock knob on the outside of the tripod legs. Secure the wing nuts finger- tight. 2. Install and tighten the leg lock knobs on the bottom braces of the tripod legs. For now, keep the legs at their shortest (fully retracted) length; you can extend them to a more desirable length later, after the tripod is completely assembled. 3. Stand the tripod and mount upright and spread the tripod legs apart as far as they will go, until the bracket is taut. Connect the accessory tray to the accessory tray bracket with the three wing screws already installed in the tray. Do this by pushing the wing screws up through the holes in the accessory tray bracket and threading them into the holes in the accessory tray. 4. Next, tighten the screws at the tops of the tripod legs, so the legs are securely fastened to the mount. Use the Phillips head screwdriver and your fingers to do this. 5. Orient the equa...
