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 aect 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 at one time.

Change to higher power (magnication) to focus in on a smaller

area. Choose the lunar tracking rate from the SkyProdigy’s

MENU tracking rate options to keep the Moon centered in the

eyepiece even at high magnications.

Lunar Observing Hints

t To increase contrast and bring out detail on the lunar surface,

use eyepiece lters. A yellow lter works well at improving

contrast while a neutral density or polarizing lter will reduce

overall surface brightness and glare.

Observing the Planets

Other fascinating targets include the ve 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

t 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,

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 nearest 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.

For safe solar viewing, use a solar lter that reduces the intensity

of the Sun’s light, making it safe to view. With a lter 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

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

late afternoon when the air is cooler.

Observing Deep Sky Objects

Deep sky objects are simply those objects outside the boundaries of

our solar system. They include star clusters, planetary nebulae,

diuse 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
