With your telescope set up, you are ready to use it for observing. This section covers visual observing hints for both solar system and deep
sky objects as well as general observing conditions which will affect your ability to observe.

To increase contrast and bring out detail on the lunar surface, use filters. A yellow filter works well at improving contrast while a neutral
density or polarizing filter will reduce overall surface brightness and glare.

Other fascinating targets include the five naked eye planets. You can see Venus go through
its lunar-like phases. Mars can reveal a host of surface detail and one, if not both, of its polar
caps. You will be able to see the cloud belts of Jupiter and the great Red Spot (if it is visible
at the time you are observing). In addition, you will also be able to see the moons of Jupiter
as they orbit the giant planet. Saturn, with its beautiful rings, is easily visible at moderate
power.

Remember that atmospheric conditions are usually the limiting factor on how
much planetary detail will be visible. So, avoid observing the planets when they
are low on the horizon or when they are directly over a source of radiating heat,
such as a rooftop or chimney. See the "Seeing Conditions" section later in this section.
To increase contrast and bring out detail on the planetary surface, try using Celestron eyepiece filters.
Often, it is tempting to look at the Moon when it is full. At this time, the face we see is fully
illuminated and its light can be overpowering. In addition, little or no contrast can be seen
during this phase.
One of the best times to observe the Moon is during its partial phases (around the time of
first or third quarter). Long shadows reveal a great amount of detail on the lunar surface.
At low power you will be able to see most of the lunar disk at one time. The optional
Reducer/Corrector lens allows for breath-taking views of the entire lunar disk when used
with a low power eyepiece. Change to higher power (magnification) to focus in on a
smaller area. Choose the lunar tracking rate from the CPC's MENU tracking rate options to
keep the moon centered in the eyepiece even at high magnifications.
