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 shieldengraved 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 t ripod 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 approximately 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 astrophotography.

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.
