ASSEMBLY

1)Carefully remove all parts from the cardboard cartons and lay them on a table or on the floor in order to take an inventory of all the pieces. Keep your box for storage or in case you ever need to ship your telescope.

2)Each aluminum tripod leg can extend to almost double its closed length. This enables the height of the telescope to be adjusted to comfortably suit most users. Each leg is equipped with a locking knob that can be loosened to perform this adjustment and then retightened. These locking knobs may already be attached to the tripod legs, or they may be packaged in a small plastic bag. If they are already attached you can extend the tripod legs to the desired height and then tighten these knobs. If they are separately packaged you will have to first insert them into the threaded holes located on the side of the black collar near the bottom of each closed tripod leg.

3)The tripod legs now need to be attached to the equatorial mount. The top of each leg is attached with a tripod bolt passed through the holes at the top of each leg. Position one of the three arms of the equatorial mount so that it fits between the leg sections. Insert a bolt through the first tripod section, then through the equatorial mount arm, and finally through the second leg section (See Fig. 1). You will note that one of the leg sections has a hexagonal (8-sided) hole. This is the side from which you insert the bolt. When the bolt comes out the other side, place a round washer and a then a wing nut over the bolt. Tighten the wing nut firmly. NOTE: Each tripod leg has a black metal flap about halfway down its length. This is a bracket to hold the accessory tray and must it be located on the inward-facing side of the tripod leg.

(Fig. 1)

4)Attach the accessory tray to the tripod by inserting an accessory tray screw downward through each of the three small holes located near the edge of the accessory tray. Lift up the black metal accessory tray bracket on one tripod leg so that it is at a right angle to the leg. Push the accessory tray screw through the accessory tray and then through the slot in the accessory tray bracket. Place a washer then a wing nut over the screw and tighten the wing nut finger tight (See Fig.

2).Repeat this procedure for the other two accessory tray brackets (See Fig. 3).

The NG90EQ is equipped with an equatorial mount, an essential component for tracking celestial objects as they move across the night sky. This mount allows users to precisely align the telescope with the North Star, simplifying the process of finding and following planets and stars. The included setting circles further assist in locating astronomical objects, making it easier for newcomers to explore the night sky.

Another notable characteristic of the NG90EQ is its user-friendly design. The telescope features an adjustable, ergonomic tripod that provides stability and supports easy height adjustment. With an optical finderscope, users can quickly locate objects before zooming in with the main telescope. The scope also includes high-quality eyepieces, offering multiple magnification options for varied viewing experiences.

Durability is a key aspect of the NG90EQ, as it is built with robust materials that withstand regular use. Its compact design makes it portable, perfect for taking to dark sky locations away from city lights.
