and seeing that same object in your telescope at night. One 
can merely be a pretty image someone gave to you. The other 
is an experience you will never forget!

A. The Moon

With is rocky and cratered surface, the Moon is one of the 
most interesting and easy subjects for your scope. The best 
time to view it is during its partial phases when shadows fall 
on the craters and canyon walls to give its features definition. 
While the full Moon may look like a tempting target, it is actu‑
ally the worst time for viewing! The light of a full Moon is too 
bright and lacks any decent surface definition.
Use an optional Moon filter to dim the Moon when it is very 
bright. It simply threads onto the bottom of the eyepiece from 
the  focuser  (you  must  first  remove  the  eyepiece  from  the 
focuser to attach the filter). You’ll find the Moon filter improves 
viewing comfort, and helps bring out the subtle features if the 
lunar surface.

B. The Sun

You can change your nighttime telescope into a daytime Sun 
viewer by installing an optional full‑aperture solar filter over 
the front opening of a SkyView Pro 127mm EQ. The primary 
attraction is sunspots, which change shape, appearance, and 
location daily. Sunspots are directly related to magnetic activ‑
ity in the Sun. Many observers like to make drawings of sun‑
spots to monitor how the Sun is changing from day to day.

Important Note: Do not look at the Sun with any optical 
instrument without a professionally made solar filter, or 
permanent  eye  damage  could  result.  Also,  be  sure  to 
cover the finder scope, or better yet, remove it altogeth­
er.

C. The Planets

The planets don’t stay put like the stars, so to find them you 
should refer to Sky Calendar at our website telescope.com, or 
to charts published monthly in Astronomy, Sky & Telescope, 
or  other  astronomy  magazines. Venus,  Mars,  Jupiter,  and 
Saturn are the brightest objects in the sky after the Sun and 
the Moon. Your SkyView Pro 127mm EQ is capable of showing 
you these planets in some detail. Other planets may be visible 
but will likely appear starlike. Because planets are quite small 
in apparent size, optional higher power eyepieces are recom‑
mended and often needed for detailed observations. Not all 
the planets are generally visible at any one time.

JUPITER 

The largest planet, Jupiter, is a great subject for 

observation. You  can  see  the  disk  of  the  giant  planet  and 
watch the ever‑changing positions of its four largest moons—
Io, Callisto, Europa, and Ganymede. Higher power eyepieces 
should bring out the cloud bands on the planet’s disk.

SATURN 

The ringed planet is a breathtaking sight when it is 

well positioned. The tilt angle of the rings varies over a peri‑
od of many years; sometimes they are seen edge‑on, while 
at other times they are broadside and look like giant “ears” 
on each side of Saturn’s disk. A steady atmosphere (good 
seeing) is necessary for a good view. You will probably see a 
bright “star” close by, which is Saturn’s brightest moon, Titan.

VENUS 

At its brightest, Venus is the most luminous object in 

the sky, excluding the Sun and the Moon. It is so bright that 
sometimes it is visible to the naked eye during full daylight! 
Ironically, Venus appears as a thin crescent, not a full disk, 
when at its peak brightness. Because it is so close to the Sun, 
it never wanders too far from the morning or evening horizon. 
No surface markings can be seen on Venus, which is always 
shrouded in dense clouds.

MARS 

The Red Planet makes its closest approach to Earth 

every two years. During close approaches you’ll see a red 
disk, and may be able to see the polar ice cap. To see surface 
detail on Mars, you will need a high power eyepiece and very 
steady air!

D. Deep­Sky Objects

Stars will appear like twinkling points of light. Even powerful 
telescopes cannot magnify stars to appear as more than a 
point of light! You can, however, enjoy the different colors of the 
stars and locate many pretty double and multiple stars. The 
famous “Double‑Double” in the constellation Lyra and the gor‑
geous two‑color double star Albireo in Cygnus are favorites. 
Defocusing a star slightly can help bring out its color.
Under dark skies, you can observe a wealth of fascinating 
deep‑sky objects, including gaseous nebulas, open and glob‑
ular star clusters, and a variety of different types of galaxies. 
Most deep‑sky objects are very faint, so it is important that 
you find an observing site well away from light pollution. Take 
plenty of time to let your eyes adjust to the darkness. Do not 
expect these subjects to appear like the photographs you see 
in books and magazines; most will look like dim gray smudg‑
es. But as you become more experienced and your observing 
skills get sharper, you will be able to ferret out more and more 
subtle details and structure.

How to Find Deep‑sky objects: starhopping

Starhopping, as it is called by astronomers, is perhaps the 
simplest way to hunt down objects to view in the night sky. It 
entails first pointing the telescope at a star close to the object 
you  wish  to  observe,  and  then  progressing  to  other  stars 
closer and closer to the object until it is in the field of view 
of the eyepiece. It is a very intuitive technique that has been 
employed for hundreds of years by professional and amateur 
astronomers alike. Keep in mind, as with any new task, that 
starhopping may seem challenging at first, but will become 
easier over time and with practice.
To starhop, only a minimal amount of additional equipment 
is necessary. A star chart or atlas that shows stars to at least 
magnitude 5 is required. Select one that shows the positions 
of many deep‑sky objects, so you will have a lot of options to 
choose from. If you do not know the positions of the constel‑
lations in the night sky, you will need to get a planisphere to 
identify them.
Start by choosing bright objects to view. The brightness of 
an object is measured by its visual magnitude; the brighter 
an object, the lower its magnitude. Choose an object with a 
visual magnitude of 9 or lower. Many beginners start with the 
Messier objects, which represent some of the best and bright‑
