cifications or to discontinue products without notices.
This does not affect your warranty rights.

Your Ferrari ZenithStar is an advanced
optical assembly. Do not disassemble
parts of the optical tube assembly or
attempt repairing your telescope without
a written authorization from William
Optics. Doing this violates and invalids
the warranty terms under the limited
product warranty. Always consult with
William Optics for details on how to
service your telescope.

CAUTION FOR SAFETY

Never directly view the sun with your
telescope! This might impair your
eyesight permanently.

Never use your Ferrari ZenithStar

USAGE

The optical tube assembly (OTA) is the heart of the
telescope and comprises the focuser, the tube with
the retractable dewshield and the lens in cell,installed
in the tube.
The fully black anodized focuser and the rosso
fiammante powder-painted high-grade aluminum
tube perfectly merge into a striking telescope with
unique functionalities. The OTA comes with a shield-
engraved cap which you should keep on the telescope
when not in use to protect the lens against dust.

Like all William Optics telescopes, the telescope is
fitted with a smooth and precise dual speed 1:10

focusing system. This means that every turn of the
large focusing knob is equivalent to ten turns of the
smaller knob. Use the fine-knob to accurately reach
optimal focus.

On the top of the focuser part, you will find a
thumbscrew, near the Ferrari shield. This is used
to lock the rotational movement of the focuser. The
focuser is designed to rotate to adjust for the best
viewing angle under any conditions. For example,
if you attach a camera to your telescope, you may
want to turn the focuser in the most comfortable
angle for taking your shot.

On the bottom side, the drawtube lock thumbscrew
locks the drawtube: if tightened, your focuser drawtube
will not extend even if you turn the focusing knobs.
Before you adjust focus with the knobs, check that
the drawtube lock is not engaged. If needed the
focuser drawtube tension can be adjusted using a
2mm allen key on the screw protruding from the black
hollow ring. The tension should be adjusted only
when necessary (for example when adding heavy
accessories to the focuser) by progressively tightening
until you reach the desired drawtube tension. Make
sure that the retaining black ring is always tight
against the focuser.

1.25" Dielectric Carbon Diagonal

This 1.25" Diagonal is used to replace the erecting prism. Unscrew the
erecting prism and replace with the provided 2" to 1.25" adapter before
tightening the Dielectric Diagonal (see page 4). The advantage of this
diagonal are the extremely high transmission thanks to the dielectric
coating (99.5%), which results in brighter more contrasted images.

Camera adapter/ 0.8x Reducer

This adapter will allow you to connect your digital SLR camera to your
Ferrari ZenithStar (T-ring adapter not included). Other than flattening
the field of view, reducing the focal length and improving the chromatic
correction, it will allow you to use your telescope as a telephoto lens.

A finderscope such as a Red Dot Finder is a useful
addition to aim your telescope more precisely at
stars. Refer to the R.D.F. instructions on how to
mount it on your Ferrari ZenithStar.

A stable camera tripod is recommended for optimal
viewing. The telescope L-bracket already comes
with standard holes to mount on these tripods.
Alt-az. Mount such as the William Optics Eazy Touch
are also recommended. In order to attach your
Ferrari ZenithStar to a camera tripod, refer to the
tripod instruction manual.

- Remember to store your telescope in a non-humid
environment. Never leave it in a heated environment
without protection for too long. Always let the telescope
dry properly before storing. Use the dewshield cap and
other accessories caps provided. If not properly stored,
the lens may develop mildew, especially after a night
observation, when the lens may have some dew on it.

- In case the lens surface should become dusty, smeared
or get fingerprints on it, first of all remove any surface dust
particle by using an air blower, then carefully proceed to
wiping the lens gently with a lint-free soft cloth. Use water

MAINTENANCE

or a lens cleaning liquid appropriate for camera lenses
for best cleaning results. A modicum of dust will not impair
the optical quality of the telescope.

- The beautiful finish of your Ferrari ZenithStar is not easy
to ruin. Nonetheless, please take care of the exterior body
tube by wiping it down with a soft cloth from time to time.
Do not use any organing solvent on your telescope, for
example alcohol, benzene and other hazardous chemicals
as this might ruin it.

Designed for multiple purposes, this little red scope
will delight you from the first minute of use. The
Ferrari ZenithStar Racing is the king of refractors.
Entirely made of automotive-grade aluminum, painted
with powder paint "Rosso Scuderia" red, it is the ultimate
optical product to add to your collection. Easy to
set-up, all you need is a camera tripod and you are
ready to go. Designed to be able to connect to DSLR
cameras (optional adapter needed), it can double as
a great telephoto lens. The zoom eyepiece will provide
magnification from 25x to 50x, enough for most
applications.

The provided erecting prism and zoom eyepiece
are interchangeable with a full series of optional
accessories for all needs. A 1.25"adapter is provided
in the package.

Before operating your telescope make sure that the
thumbscrew on the erecting prism is locking the
eyepiece in place so that you do not risk accidentally
dropping your precious eyepiece.

A normal optional mirror-based diagonal would result
in images that are correctly oriented up-and-down
but reversed left-for-right. The Ferrari erecting prism
(Amici prism), which is provided in the package,
allows you to see a correct image as if you were
looking with your eyes. Make sure that the prism
is locked onto the focuser and with the right angle.

Because the Ferrari ZenithStar is well suited to view
nebulae, star clusters and large galaxies and comets,
we recommend the usage of high quality wide-angle
eyepieces. The William Optics SWAN, UWAN and
SPL eyepieces are available in a variety of focal lengths.
To calculate the magnification of your telescope divide
388 (the focal length of the Ferrari ZenithStar Racing)
by the focal length of the eyepiece. For example, if you
use a UWAN 4mm, you will develop 388/4 = 97x
(magnifications). Keep in mind that the atmosphere
plays an important role in seeing conditions, and only
the best conditions will support night-time high-power

viewing (above 70x). Additional power under less-than
-ideal atmospherical conditions will not result in an
increase in viewable details, and lower-power (longer
focal length) eyepieces should be preferred instead.
The maximum theoretical magnification we recommend
for this telescope, in a night of perfect seeing, is approxi-
mately 130x. The provided zoom eyepiece is an excellent
"all-in-one" eyepiece which will yield a magnification
of 25x to 50x.

Mirror diagonals have the advantage of a higher
light transmission compared to a prism-based system.
We therefore recommend them for astronomical work,
especially where lunar or planetary observations are
involved. The Ferrari ZenithStar telescope line is
designed to work with optional SCT-thread 2"
diagonals, 1.25" diagonal and with accessories
with SCT threads such as the 1.25" erecting prism
provided in the package. It is suitable for both day-


time and nigh-time viewing, and doubles as an
outstanding travel scope. For serious astronomers,
we recommend the purchase of a 2" star diagonal
to make the most of this little telescope. To use
1.25" diagonals, find included in the package an
adapter, which mounts on the drawtube in place
of the erecting prism, when you want to use a mirror
diagonal.

This scope is suitable for wide-field astrophotography.
A CCD camera and a German equatorial mounts
(designed to track the stars in their movement in
the sky) are necessary for best results, but you
may want to try other set-ups with DSLR for example.
To connect your Ferrari ZenithStar to a DSLR camera,
you will need an optional adapter.
This adapter has the dual function of reducing the
focal length (making the telescope "faster" and
therefore brighter and more suited to be used as a
telephoto lens) and of flattening the field of view at
the corner when using the telescope for astrophoto-
graphy.

Never aim your telescope at the Sun without proper
solar filters installed on the front of the telescope.
Doing so for even a short moment may permanently
damage your eyes. Proper solar filters are made by
reputable manufacturers and designed to fit tightly
over the front of the dewshield. Solar eyepiece filters
are not considered safe and should not be used.
With proper solar filtration in place, it will be easy
to see amazing details of the sun such as solar
spots. Contact a William Optics authorized astronomy
dealer for more details about proper solar filters.
