With the Moon visible in the sky, set up your telescope with
the 20mm eyepiece installed.
Look through the telescope’s 20mm eyepiece. Gently turn the
focus knobs to adjust the sharpness of the image.
You can view many other celestial objects, such as planets,
star clusters and nebulae using this same technique if you
know where to find them in the
night sky.
The best and easiest target for you to try to view first is
the Moon. Try observing the Moon at different points in
its phase cycle. The best time to view the Moon is from
two days after a New Moon up to a few days before a
Full Moon. During this period, you will be able to see the
most detail in the craters and lunar mountain ranges.
To get a closer view of the Moon, loosen the set screws on
the focuser and remove the 20mm eyepiece. Replace it with
your 10mm eyepiece and tighten the set screws to secure it
in place. The 10mm eyepiece will give you significantly more
magnification, making the Moon appear much larger.
Note: You may need to adjust the focus knobs when you
change eyepieces, to make sure you are getting the
sharpest image possible.
Move the telescope so that it is roughly pointing toward
the Moon.
Look through the finderscope and locate the crosshair reticle.
Continue moving the telescope until the crosshair appears
over the Moon.
