WARNING: Never look directly at the Sun
through your telescope or its finder scope— 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. Assembly
Carefully open all of the boxes in the shipping container. Make sure all the parts listed in the parts list are present. Save the boxes and packaging material. In the unlikely event that you need to return the telescope, you must use the original packaging.
Assembling the telescope should take only about 30 minutes. All screws should be tightened securely to eliminate flexing and wobbling, but be careful not to over-tighten or threads may strip. No tools, other than the ones provided, are need­ed. Refer to Figure 1 during assembly.
During assembly (and anytime, for that matter), do not touch any of the lenses of the telescope, finder scope, or eye­pieces, or the mirror of the diagonal, with your fingers. The optical surfaces have delicate coatings on them that can be damaged if touched inappropriately. Never remove any lens assembly from its housing for any reason, or the product warranty and return policy are void.
1. Lay the altazimuth mount on its side. Attach the tri­pod legs one at a time to the mount using the screws installed in the tops of the tripod legs. Remove the screw from the leg, line up the holes in the top of the leg with the holes in the base of the mount, and reinstall the screw so it passes through the leg and the mount. A washer goes between the screw head and the tripod leg, and between the wingnut and tripod leg. Tighten the wingnuts only finger-tight, for now. Note that the acces­sory tray bracket attachment point on each leg should face inward.
2. Tighten the leg lock knobs at the base 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 scope is completely assembled.
3. With the tripod legs now attached to the altazimuth mount, stand the tripod upright (be careful!) and spread the legs apart enough to connect each end of the acces­sory tray bracket to the attachment point on each leg. Use the screw that comes installed in each attachment point to do this. First remove the screw, then line up one of the ends of the bracket with the attachment point and reinstall the screw. Make sure the accessory tray bracket is oriented so the ribs in its plastic molding face down­ward.
4. Now, with the accessory tray bracket attached, spread the tripod legs apart as far as they will go, until the bracket is taut. Attach the accessory tray to the accessory tray bracket with the three wingnut-head screws already installed in the tray. This is done by pushing the screws up through the holes in the accessory tray bracket, and then threading them into the holes in the accessory tray.
