Base Lock Screw P05 P06 Crafting the Earth's Finest Astronmical Instruments Connection Instructions ( Aligning R.D.F. ) Usage The Zenithstar FD series is designed as the ultimate, versatile short tube refractor. It is perfect for travel, piggybacking/guiding scope, astrophotography, rich-field observations. We recommend purchasing a WO 2" star diagonal to make the most of this telescope. Because the Zenithstar FD is well suited to viewing nebulae, clusters, large galaxies and comets, we recommend the use of high quality wide-angle eyepieces. The WO UWAN series eyepieces are available in a variety of focal lengths and make a perfect complement to this telescope. Viewing the moon and planets is also very impressive at magnifications of 120X when seeing conditions permit. 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 alignment of the finder needs to be performed only when necessary. We recommend aligning during daytime by point telescope and finder at the same far object. www.william-optics.com the best seeing conditions will support high power viewing. Additional power under less Step-1 Find a distant object in the telescope with a low power eyepiece. 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. Step-2 View Field of Red Dot Finder. (with WO Erecting Illuminated Red Dot Finder) Use a 2mm Allen key to loosen the setscrew on the left side of the RDF, near the bracket under the letter "R". Using a 2.5 mm Allen key make adjustments to the Alt-Az adjustments (marked R and UP) until the red dot in the reticule overlays the same object as the center of the eyepiece view. 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. Optional accessories from WO include black anodized mounting rings and plates, super high quality 2" Quartz star diagonals which provide for superior viewing and high quality images. A recommended Alt-az. mount for this telescope is William Optics high-quality mount, EazyTouch. This beautiful mount is easy to use and will provide a perfect, quick-to-setup addition to your collection. The ZSFD is suitable for large-field astrophotography; the accessories Chart on page 03 provides additional details on photographic accessories for various CCD, digital and film cameras. 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 Alignment Setcrews Reticule Selector 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. View Field of Telescope. (with WO Dielectric) Step-3 Brightness Adjustment Using a high magnification eyepiece (short focal length) repeat this procedure for fine alignment. P07 P08 Crafting the Earth's Finest Astronmical Instruments Caution for Safety Drawtube Lock Thumb Screw Caution! Never directly view the Sun with your telescope! Do not aim your telescope at the Sun without a front mounted high quality professionally manufactured solar filter. Viewing the Sun without the proper protection may result in permanent severe damage to your eyes, and even cause blindness. Contact your Authorized WO Dealer 2.5mm Allen key Focuser Tension Adjustment Screw if you are interested in purchasing a compatible and proper solar filter. Always place the telescope on a flat surface, to prevent it from falling Crafting the Earth's Finest Astronmical Instruments P10 and injuring yourself or others. Never use the telescope in the rain or in conditions where it may get wet. The telescope is not designed to be waterproof. If the telescope accidentally gets caught in the rain, immediately wipe off all water using a clean dry soft cloth. If the telescope gets totally soaked in water, immediately contact your Authorized WO Dealer for service instructions. Do not disassemble or attempt to repair your telescope without a written authorization from William Optics Corp., as this violates the warranty terms under the limited product warranty, and negates any guarantee. All WO telescopes, including ZenithStar, are now fitted with a smooth and precise dual speed 1:10 focusing system. www.william-optics.com 1:10 means that for every ten full rotations of the small fine-focus knob the large knob rotates once. The focuser drawtube tension can be adjusted using a 2.5mm Allen key on the screw protruding from the black hollow ring. Tension should be adjusted only when necessary by progressively tightening the screw until you reach the desired tension. Make sure that the black ring is always tight against the focuser. Storage and Cleaning We recommend storing all equipment in an air tight container with desiccate packages to remove unwanted humidity from the air. Never leave the telescope in a humid environment, and avoid leaving the scope in a hot heated environment. If not properly stored, it is possible for the scope to develop mildew growth or other preventable conditions. Be careful after a night of observing when conditions might leave dew on the lens, and allow the scope to air dry in a room temperature environment before storing the telescope. If the front lens surface becomes dusty, smeared, shows fingerprints, or any other surface build up, the following steps can be taken to clean the lens. First, gently blow away any surface dust or particles with a clean air blower (canned or compressed air is not recommended). Second, use a photographic quality optical cleaning solution and cloths to gently wipe the surface clean. A clean cloth should be used every time that cleaning is needed. With proper care, and protection, cleaning should rarely be needed. The Zenithstar has a beautiful high gloss anodized finish that can be easily smudged with fingerprints; however this will not harm the finish. A slightly dampened clean soft cloth with plain water should be enough to clean the surface. Please avoid any harsh chemical cleaners or organic solvents like benzene, alcohol, etc, as these may ruin the finish. Bundle Equipment 1.
