 HOW TO USE YOUR FERRARI ZENITHSTAR

Designed for multiple purposes, this attractive telescope 
will delight you from the very first minute of use. The 
optical tube assembly (OTA) is the heart of the telescope 
and comprises of the focuser, the tube with the retractable 
dewshield and the lens in cell installed in the tube.
The fully black anodized focuser and the carbon fiber 
tube perfectly merge into a striking telescope with 
unique functionalities. The OTA comes with a Prancing 
Horse 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. The stainless steel reinforcements make 
the focuser a masterpiece of mechanics. After adjusting 
the focuser tension with an allen screw, your focuser 
will hold even heavy accessories without problems.

On the top of the focuser part, you will find a thumbscrew. 
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.

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

Eyepiece

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
nebular, 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 
430 (the focal length of the Ferrari ZenithStar Anniversary) 
by the focal length of the eyepiece. For example, if you 
use an optional UWAN 4mm eyepiece, you will develop 
430/4 = approx. 108x (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 
approximately 130x. The provided zoom eyepiece is 
an excellent "all-in-one" eyepiece which will yield a
magnification of 20x to 65x.

Adapter

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. If you wish, the Ferrari ZenithStar telescope 
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. 
Your instrument 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 the 
potential of the telescope. In order to use 1.25" 
diagonals, you can find included in the package an 
adapter which mounts on the drawtube in place of the
erecting prism,. Please replace the erecting prism
with the adapter when you want to use a 1.25" mirror 
diagonal.

Astrophotography and use as a telephoto lens

This scope is well suitable for wide-field astrophotography
due to its exceptional optical design. 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 astrophotography.

Solar Observations

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.

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

- Do not attempt to open the telescope as this will invalidate 
  the warranty. The tube and lens cells are not designed 
  to be detached. In case you need any support, please
  contact William Optics or your closest authorized dealer. 

- 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.

OPTIONAL  ACCESSORIES

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.

This adapter will allow you to 
connect your DSLR 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 correc- 
tion, it will allow you to use your 
telescope as a telephoto lens.
