Summary

1. Knowing your telescope

2. Getting Started

3. Assembly

Assemble the telescope base by connecting panels and discs, then attach the optical tube to the base.

4. What is the Balance Adjustment System and how to use it

4.1. How to adjust the friction

Adjust the disc position to match the knob's tip to the recess for optimal performance and friction.

5. Optional accessories (not included)

5.1. The focuser

Install the focuser by releasing and retightening set screws to hold the base tube securely.

5.2. Finderscope

The finderscope aids object location. This telescope uses Vixen-compatible findershoes.

5.3. Eyepiece Rack

An eyepiece rack holds eyepieces and accessories for quick changes during observation.

6. What can been seen with this telescope

6.1. The Moon

Observe craters and features like the Marea on the Moon. Best seen when not full.

6.2. Jupiter

View Jupiter's disc with two bands and its Galilean moons: Io, Europa, Ganymedes, Callisto.

6.3. Saturn

See Saturn's rings, discernible at 60x magnification, and potentially Cassini's division.

7. Using the accessories, a bit of math to understand how all it works

7.1. Power (magnification)

Calculate magnification by dividing telescope focal length (1200mm) by eyepiece focal length.

7.2. Barlow Lens (not included)

A Barlow lens multiplies the telescope's focal length, increasing magnification.

7.3. Erecting lens (not included)

An erecting lens provides an upright image and increases magnification by 1.5x.

APPENDIX A

1. Knowing your finderscope

Identify parts of the red-dot finderscope, including the red-dot case, controls, and bracket.

2. Getting Started

Install the battery, turn on the finderscope, and attach its bracket to the telescope's finderbase.

3. Aligning the finderscope

Align the red-dot by centering a distant object in the telescope and adjusting knobs to match the dot.

4. Replacing the battery

Replace the CR2032 battery when the red-dot dims. Turn off the finderscope when not in use.
