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.
During assembly (and anytime, for that matter), DO NOT touch
the surfaces of the telescope objective lens or the lenses of the
C
ongratulations 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.

damage could result. Young children should use
