The Fluoro-Star 110 lens is a 3 elements oil-space APO. This design consists of a heart of super low dispersion glass surrounded by 2 elements of crown glass. Our design reduces any secondary spectrum to an unbelievable degree. The superb color correction allows for the use of extremely high magnification without image breakdown, challenge subjects such as the Moon or Venus.

Because the Fluorostar is well suited to viewing nebulae, clusters, large galaxies and comets, we recommend the use of high quality wide angle eyepieces. The WO SWAN (72o ) and UWAN (82 o ) series eyepieces are available in a variety of focal lengths. Viewing the moon and planets is also impressive at magnifications of 120X when seeing conditions permit. This telescope is also well suited for higher power observations with planetary eyepieces. To calculate the magnification of your telescope and eyepiece combination, divide the telescope focal length in mm by the eyepiece focal length in mm. Keep in mind that the atmosphere plays an important role in seeing conditions, and only the best seeing conditions will support high power viewing. Additional power under less than ideal seeing conditions will not result in an increase in viewable details, and lower powered eyepieces should there be used under those conditions. It's easiest to locate objects using low power eyepieces (20X magnification) and then zoom in by switching to higher powered eyepieces. The largest field of view will be seen using a 12X low power-wide field of view eyepiece. Also remember to let the telescope reach thermal stability for optimal results. A triplet lens takes longer than a doublet to cool down. A stable tripod or mount is recommended for optimal viewing. This includes high quality photography tripods, and German Equatorial mounts, which are designed for astronomical use and include precise tracking of celestial objects. William Optics is marketing a very practical Alt-Az mount too, which will perfectly complement any of its refractors. The Fluorostar has been specifically designed for astrophotography; it will produce excellent results when used with the proper equipment. Being this a high-end astrophotography telescope, it should be mounted on a good mount. Please see our website for examples of photos taken with these telescopes. The Accessories Chart on page 4 provides additional details on photographic accessories for various CCD, digital and film cameras. Optional accessories from WO include mounting rings and plates, super high-quality 2" Quartz star diagonals, and 2" Erecting Prisms (45o and 90o ), all of which provide for superior viewing and high quality images. Never aim your telescope or finderscope at the Sun without proper Solar filters installed on the front of the telescope. Doing so for even a moment may permanently damage your vision. Proper Solar filters consist of a filters made by reputable manufacturers, designed to fit tightly over the front of the dew shield. Solar eyepiece filters are not considered safe, and should not be used. With proper front mounted Solar filters, the telescope will not be harmed by viewing the Sun. Contact your Authorized WO Dealer for further information on the brands, sizes, and prices of proper solar filters. Important Notice William Optics warranty does not cover damage to the focuser due to inappropriate tension setting. www.william-optics.com This focuser is designed to hold many pounds without problems. If nonetheless your setup requires additional tension adjustment, please use the tension allen screw under the focuser. In order to avoid sagging or denting of the focuser steel reinforcement, it is necessary to adjust tension ONLY when the drawtube is FULLY EXTENDED. Extend the focuser drawtube to its full 93 mm as in the picture here above before performing adjustment. Storage and Cleaning We suggest placing all accessories inside an airtight container with desiccative control. Secondly, remember to store the telescope in a non-humid environment, never leave it in a hot heated environment. If not properly stored, it may develop mildew growth and other preventable build up. Be particularly careful after a night observation that the lens has no dew on it before storing the telescope away. In case the lens surface becomes dusty, smeared, or gets fingerprints or fungus build-up on it, first of all, remove any surface particle by using an air blower, then carefully proceed to wiping the lens gently with a lint-free proper soft cloth. Use a lens liquid cleaner to get the best cleaning result. Make sure you change your cloth to a new one from time to time. The above-mentioned indications are not necessary if you carefully protect your telescope. The beautiful multi-layer Dupont paint white finish of your Fluorostar 110 is not easy to ruin. Nonetheless take care of the exterior body tube by wiping it down with a slightly damp soft cloth from time to time. Water should be enough to do the job. Please do not use any organic solvent on your telescope, for example alcohol, benzene and other hazardous chemical as this might ruin it. P09 P10 Crafting the Earth's Finest Astronomical Instruments Caution for Safety Caution! Never directly view the sun light with your telescope. Do not aim your Fluorostar 110 at the Sun because this might impair your Loss of eyesight can occur when your telescope is not properly protected by solar viewing filter. (Solar filters can be easily purchased through your WO Authorized Dealers). Always place the optical telescope assembly (OTA) on a completely flat surface, unstable placement of telescope may cause it to fall, and if handled without caution, it may easily injure yourself and others. Never use your telescope under rainy conditions: this telescope is not designed to be water-proof. If your telescope accidentally gets caught in rain, please wipe down the water with a dry clean cloth, but if the lens gets totally soaked by water, please contact your WO Authorized Dealer right away for details on a service solution. Do not disassemble or attempt repairing your telescope without a written authorization from William Optics Corp. : this violates the warranty terms under the limited product warranty section and invalids any guarantee. Always consult with your local WO Authorized Dealer or with William Optics Corp. for details on how to service your telescope.
