After you have read and followed the instruction manual to this point, the telescope is set up and you are
ready to begin your observing adventure.
To enable you to find objects you should have a set of Star Charts or a Planisphere. The location of the
planets may appear in local newspapers.
A. The Moon is an awesome first object to observe. The best observing occurs during the partial phases
as a full Moon is too bright.
At low power you can see the complete Moon and at high powers you can see lunar details such as
mountain ranges, craters and rills.
B. Five of the planets are easy targets for your telescope.
•
See Jupiter with its great red spot, study the cloud bands and watch its moons shuttle back and forth.
•
Study Saturn and its splendid ring structure.
•
Observe Mars and see its polar cap.
•
Watch Venus and Mercury as they go through their moon-like phases.
C. The Sun is quite safe to view if you use the proper solar filter. You can detect and watch the
ever-changing sunspot activity.
D. Deep-Sky objects (those outside our solar system) offer a lifetime of observing. There are hundreds of
objects within the realm of your telescope including open and closed star clusters, planetary and diffuse
nebulae, galaxies, double stars and occasional comets. The amount of detail you can see is dependent
on your observing site (dark sky rural locations are best), atmospheric conditions, brightness of the
object, collimation and your observing experience.

With proper care your telescope should rarely need any maintenance work.
A. When not in use, always replace all lens covers to keep dust and contaminants off the optical surfaces.
B. A small amount of dust on any optical surface is ok. If the dust builds up then use a can of compressed
air and then a camel's hair brush to remove the dust.
C. If the mirrors need cleaning, they should be cleaned by a professional. Either have your instrument
serviced by a telescope repair facility or return it to the factory.
D. Collimation or alignment of the optical system is done at the factory before shipment.
1. If your telescope has received very rough handling during transport or is dropped, it may need
collimation.
To check if your telescope is in collimation the sketch below will help you. If you look into the
eyepiece adapter (without an eyepiece) at the top of the focuser, this is what you should see. If the
reflection of your eye is off center, then collimation is necessary.
