under these conditions is greatly reduced. Also, when

photographing under these conditions, the processed

ﬁlm may come out a little grainier than normal with lower

contrast and underexposed.

want to remove them when observing with an eyepiece

attached to the telescope. When using a camera, however,

you should always wear corrective lenses to ensure the

sharpest possible focus. If you have astigmatism, corrective

lenses must be worn at all times.

CelesTIal observIng

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.

Observing the Moon

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rst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

in on a smaller area. Choose the lunar tracking rate from the

hand control’s MENU tracking rate options to keep the moon

centered in the eyepiece even at high magniﬁcations.

Lunar Observing Hints

• To increase contrast and bring out detail on the lunar

surface, use eyepiece ﬁlters. A yellow ﬁlter works well at

improving contrast while a neutral density or polarizing

ﬁlter will reduce overall surface brightness and glare.

Observing the Planets

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.

Planetary Observing Hints

• 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.

Observing the Sun

Although overlooked by many amateur astronomers, solar

observation is both rewarding and fun. However, because

the Sun is so bright, special precautions must be taken when

observing our star so as not to damage your eyes or

your telescope.

Never project an image of the Sun through the

telescope. Tremendous heat build-up may result inside

the optical tube. This can damage the telescope and/or

any accessories attached to the telescope.

the Sun’s light, making it safe to view. With a ﬁlter you can see

sunspots as they move across the solar disk and faculae, which

are bright patches seen near the Sun’s edge.

Solar Observing Hints

• The best time to observe the Sun is in the early morning or

late afternoon when the air is cooler.

• To center the Sun without looking into the eyepiece, watch

the shadow of the telescope tube until it forms a circular

shadow.

• To ensure accurate tracking on LCM models, be sure to

select solar tracking rate.

Observing Deep Sky Objects

Deep sky objects are simply those objects outside the

boundaries of our solar system. They include star clusters,

planetary nebulae, diffuse nebulae, double stars and other

galaxies outside our own Milky Way. Most deep sky objects

have a large angular size. Therefore, low-to-moderate power is

all you need to see them. Visually, they are too faint to reveal

any of the color seen in long exposure photographs. Instead,

they appear black and white. And, because of their low surface

brightness, they should be observed from a dark sky location.

Light pollution around large urban areas washes out most

nebulae making them difﬁcult, if not impossible, to observe.

Light Pollution Reduction ﬁlters help reduce the background sky

brightness, thus increasing contrast.
