[. . . ] Because the Zenithstar 66 are 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. To calculate the magnification of your telescope and eyepiece combination, divide the telescope focal length in mm by the eyepiece focal length in mm. Focuser Tension Adjustment Screw Drawtube Lock Thumb Screw 2. 5 mm Allen key All WO telescopes, including ZenithStar, are now fitted with a smooth and precise dual speed 1:10 focusing system. 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 1. 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. 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 a12X low power-wide field of view eyepiece. 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 which provide for superior viewing and high quality images. The Zenithstar telescopes are suitable for large-field astrophotography; the Petzval version features a very flat and well corrected field of view, the SD version has great color correction at a fast speed of f/5. 9, whereas the triplet version has an excellent color correction. Please see our website for examples of photos taken with these telescopes. The Accessories Chart on page 05 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. 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. [. . . ] VR-1 filter improves seeing on bright objects like the Moon "Violet-Reducer".
