Explore Scientific 134mm Equatorial Newtonian Telescope User Manual

Quick guide from the manual

This manual provides instructions for the Explore Scientific 134mm Equatorial Newtonian Telescope. Safety Warning: Never look directly at the sun with this device, as it will cause instant and irreversible eye damage or blindness. Always use adult supervision for children. The telescope is designed for astronomical use; terrestrial objects may appear inverted or rotated, which is normal for this optical design.

Assembly

1. Open the tripod legs and extend them to the desired height, ensuring the top remains level. Attach the accessory tray to the center leg braces.

2. Place the equatorial mount head onto the top of the tripod and tighten the attachment knob from underneath.

3. Screw the counterweight shaft into the mount. Slide the counterweight onto the shaft and tighten the lock knob.

4. Attach the slow-motion controls to the shafts on the mount head. The longer control attaches to the declination (Dec) shaft, and the shorter one attaches to the right ascension (RA) shaft.

5. Secure the telescope tube to the mount using the cradle rings and dovetail plate. Ensure the saddle lock knob is tightened securely.

Attach and Align the 6x30 Finderscope

1. Remove the two thumb nuts near the focuser, place the finderscope base over the bolts, and reinstall the nuts.

2. To align, point the main telescope at a distant object (at least 1/4 mile away) and center it in the eyepiece.

3. Look through the finderscope. If the target is not centered, adjust the alignment thumbscrews on the finderscope rings until the target is centered in both the main telescope and the finderscope.

Balancing the Telescope

1. Loosen the RA lock and rotate the telescope so the counterweight shaft is horizontal. Slide the counterweight until the telescope remains in position without drifting.

2. Unlock the Dec axis. Loosen the cradle ring locks and slide the telescope tube back or forth until it is balanced on the Dec axis.

Collimating the Optics

1. Collimation ensures the mirrors are aligned for the best image quality. This is done by adjusting the secondary mirror (using the three collimation screws) and the primary mirror (using the spring-loaded knobs).

2. The goal is to have the reflection of your eye, the secondary mirror, and the primary mirror center mark appear concentric when looking through the focuser draw tube.

3. Perform fine collimation on a star (like Polaris) at high magnification, adjusting the primary mirror knobs until the star image is symmetrical.
