Orion 9025, 9086, 9024 instruction manual Table of Contents, Parts List, Assembly

Congratulations on your purchase of a quality Orion telescope. Your new Skywatcher 90mm EQ Refractor is designed for high-resolution viewing of astronomical objects. With its precision optics and equatorial mount, you’ll be able to locate and enjoy hundreds of fascinating celestial denizens, including the planets, Moon, and a variety of deep-sky galaxies, nebulas, and star clusters.

If you have never owned a telescope before, we would like to welcome you to amateur astronomy. Take some time to familiarize yourself with the night sky. Learn to recognize the patterns of stars in the major constellations; a star wheel, or planisphere, available from Orion or from your local telescope shop, will greatly help. With a little practice, a little patience, and a reasonably dark sky away from city lights, you’ll find your telescope to be a never-ending source of wonder, exploration, and relaxation.

These instructions will help you set up, properly use, and care for your telescope. Please read them over thoroughly before getting started.

2. Assembly

Carefully open all of the boxes in the shipping container. Make sure all the parts listed in Section 1 are present. Save the boxes and packaging material. In the unlikely event that you need to return the telescope, you must use the original packaging.

Assembling the telescope for the first time should take about 20 minutes. No tools are needed other than the ones provid- ed. All bolts 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.
