P05 P06 Crafting the Earth's Finest Astronmical Instruments connection point for finderscope bracket Connection Instructions ( Aligning Finderscope ) Usage The Zenithstar 80 is designed to work with both 1 1/4 inch and 2 inch diameter eyepieces in various focal lengths, for both daytime and nighttime viewing. Because the Zenithstar 80 is well suited to viewing nebulae, clusters, large galaxies and comets, we recommend the use of high quality wide angle eyepieces. The WO SWAN and UWAN 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. Align the finderscope pointing at the same object as the telescope. To calculate the magnification of your telescope and eyepiece combination, divide the telescope focal length in mm by the eyepiece focal length in mm. For example, a 4mm suggested maximum magnification for the Zenithstar 80 is 120X. 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 eyepiece in Zenithstar 80 will display an image of 120X. (480mm / 4mm = 120). The www.william-optics.com Step-1 Find a distant object in the telescope with a low power eyepiece. 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. Step-2 Align the finderscope by pointing at the same object, then loosen or tighten the alignment screws. Alignment Screws. 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 mounting rings and plates, super high quality 2" Quartz star diagonals, and 2" Erecting Prisms, all of which provide for superior viewing and high quality images. The Zenithstar telescope has not been specifically designed for astrophotography; Step-3 Use a high power eyepiece and repeat this procedure. however it is able to produce very good results when used with the proper equipment. Please see our website for examples of photos taken with these telescopes. The Accessories Chart on page 13 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 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 View Field of Telescope. (with WO Erecting Prism) View Field of Finderscope. (with WO Erecting Illuminated Finderscope) 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 Erecting Finderscope (Note: The image will be reversed left to right if a standard star Diagonal is used) P07 P08 Crafting the Earth's Finest Astronmical Instruments Caution for Safety Caution! Never directly view the Sun with your telescope! Do not aim your telescope at the Sun without a front mounted high Focuser Tension Adjustment Screw 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 if you are interested in purchasing a compatible and proper solar filter. 2.5mm Allen screw driver 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. The focuser's tension can be adjusted using a 2.5mm allen wrench if needed. The Focuser Lock Thumb Screw is used to tighten down the focuser's travel while in use to prevent the focuser from accidentally moving. This is most likely when the telescope is pointed upwards and the additional weight of large eyepieces or photography equipment may make the focuser move on its own. Please consult with your consult with your Authorized WO Dealer or WO directly if you have any questions before adjusting the focuser. www.william-optics.com 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. Standard Equipment 1.
