P05 P06 Crafting the Earth's Finest Astronomical Instruments Connection Instructions ( Aligning Finderscope ) Align the finderscope pointing at the same object as the telescope. Step-1 Alignment Screws. Find a distant object in the telescope with a low power eyepiece. Step-2 Align the finderscope by pointing at the same object, then loosen or tighten the alignment screws. Step-3 Use a high power eyepiece and repeat this procedure. View Field of Finderscope. (with WO Erecting Illuminated Finderscope) View Field of Telescope. (with WO Erecting Prism) Note: The image will be reversed left to right if a standard star Diagonal is used. P07 P08 Crafting the Earth's Finest Astronomical Instruments www.william-optics.com Usage The Megrez 80 is designed to work with both 1 1/4" and 2" diameter eyepieces in various focal lengths, for both daytime and nighttime viewing. Because the Megrez 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 130X 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. For example, a 4mm eyepiece in a 480mm Megrez Fluorite will display an image of 120X. (480mm / 4mm = 120) The suggested maximum magnification depends on the model of scope as well, with the Megrez Fluorite able to handle the most power and remain color free. Some C.A. (Chromatic Aberration) may be introduced by the eyepiece or other accessories, so high quality eyepieces and accessories are highly recommended to maximize the viewing ability of the telescope. Focuser Lock Thumb Screw Focuser Tension Adjustment Screw 2.5mm Allen screw driver 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. 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. Its 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. 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 Megrez telescope line has been specifically designed for astrophotography, with the Fluorite models best suited to the high quality imaging. Please see our website for examples of photos taken with these telescopes. The Megrez 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 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. 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 Megrez is coated in a durable and beautiful multi-layer Dupont white paint finish is tough and resistant to most natural elements but care should be taken to keep it clean. 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 paint. P10 P09 Crafting the Earth's Finest Astronomical Instruments www.william-optics.com 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 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. Always place the telescope on a flat surface, to prevent it from falling 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. Optional Equipment In order to operate your Megrez 80 you will need the following minimum equipment: A sturdy tripod for astronomical or birding usage or a mount (equatorial or ALTAZ). A mirror diagonal or erecting prism (The WO 2" Dielectric Diagonal is strongly recommended for better results in star observation and digital photography. A topquality Dielectric Quartz model is also available now). At least one or two good eyepieces (9 to 40 mm wide-field recommended) depending on the application. For Megrez 80 ED, a 2" extender already provided. For astrophotography, a photo adapter plus a T-mount connection are necessary. William Optics offers a 0.8x reducer flattener with CCD camera adapter. Please refer to our Accessories Chart on page 02.
