With your telescopeset up, you are ready to use it for observing. This section coversvisual observing hints for both
solarsystem and deep sky objects as well as general observingconditions which will affect your ability to observe.

Often, it is temptingto lookat the Moon when it is full. At this time, the face we see is fully illuminated and its light
canbe overpowering. Inaddition, little or no contrast can be seen during this phase.
One of the best times to observe the Moon is duringits partial phases
(aroundthe time of first or third quarter). Long shadowsreveal a great
amountof detail on the lunar surface. Atlow power youwill be able to
see most of the lunar disk at one time. Change to higher power
(magnification)to focus in on a smaller area. Choosethe lunar tracking
rate from the NexStar's MENU tracking rate options to keep the moon
centered in the eyepiece even at high magnifications.

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

Otherfascinating targets include the five naked eye planets. Youcan see Venus go through its lunar-like phases. Mars
can reveal a host of surfacedetail and one, if not both, of its polar caps. You will be able to see the cloud belts of
Jupiter and thegreat Red Spot (if it is visible at the time you are observing). Inaddition, you will also be able to see
themoons of Jupiter as they orbit the giant planet. Saturn,with its beautifulrings, 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 theyare low on the horizon or when
theyare di rectly 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,
tryusing Celestron eyepiece filters.
