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.

100 EQ specifications

The Orion 100 EQ is a high-performance telescope designed for both novice and experienced astronomers. Combining precision engineering with user-friendly features, this telescope offers an exceptional observing experience.

One of the standout features of the Orion 100 EQ is its 100mm diameter aperture, which allows for ample light gathering capabilities. This feature is essential for observing faint celestial objects, making it ideal for viewing planets, star clusters, and nebulae. The optics are made from high-quality glass and are fully coated to enhance light transmission and image clarity.

The computer-controlled equatorial mount of the Orion 100 EQ is another significant advancement in its design. This mount utilizes a durable, smooth operation mechanism that allows for easy tracking of celestial objects as they move across the night sky. The built-in dual axis slow motion controls provide astronomers with the ability to make fine adjustments to their viewing angle, ensuring that the object of interest remains centered in the eyepiece.

Another key technology included in the Orion 100 EQ is its robust and portable design. Weighing in at just under 25 pounds, the telescope is lightweight enough to transport easily but offers the stability necessary for steady views during observation. The adjustable aluminum tripod further enhances the telescope's stability while providing a sturdy platform for observers.

For beginners, the Orion 100 EQ is user-friendly and easy to set up. The telescope comes with a detailed instruction manual that guides users through the assembly process. Moreover, Orion includes a selection of eyepieces and a finderscope to assist users in locating celestial objects quickly. A 25mm Plössl eyepiece and a 10mm Plössl eyepiece come standard, allowing for a range of magnifications suitable for various observing conditions.

In terms of characteristics, the Orion 100 EQ stands out with its solid build quality and intuitive design. Its sleek black finish not only adds to its aesthetic appeal but also ensures both durability and resistance to weather conditions. The telescope's user-friendly nature, combined with its impressive optical performance, makes it a perfect choice for astronomy enthusiasts.
