Make sure all the parts listed in the Parts List are present and familiarize yourself with their features. Please keep the origi- nal shipping box and interior packaging. In the unlikely event that you should need to ship the original telescope back to Orion, you should use the original packaging.

Assembling the telescope for the first time should take about 30 minutes. No tools are needed other than the ones provid- ed. 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 objective lens, the lenses of the finder scope, or eyepiece lenses with your fingers. The optical surfaces have delicate coatings on them that can easily be damaged if touched inappropriately.

1.Lay the equatorial mount on its side. Attach the tripod legs one at a time to the mount using the leg attachment screws. line up the holes in the top of the tripod leg with the holes in the base of the mount, and install the screw so it passes through the leg and the mount with one washer on both sides of the tripod leg. Tighten the wingnuts only fin- ger-tight, for now.

2.Insert and tighten the leg lock knobs into 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.Stand the tripod upright and spread the tripod legs apart as far as they will go, until the accessory tray bracket is taut. Attach the accessory tray to the bracket with the three wingnut screws already installed in the tray. Push the screws up through the holes in the bracket, then thread them into the holes in the tray.

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.
