The computer-controlled M3 mirror allows either Nasmyth port to be selected in just a few seconds, allowing observers to easily transition between imaging and visual use, or other instrumentation. Eyepieces remain at a constant height, greatly simplifying access to the telescope for public observatories. The Nasmyth focus is along the altitude axis so the telescope does not need to be re-balanced when changing equipment. This translates into consistent optical performance and unchanging focus over temperature changes. With no polar alignment required, the Alt-Az mount is far more intuitive to use than a German Equatorial mount.įeatures: Light-Weighted Fused Silica Opticsįused Silica has a coefficient of thermal expansion six times lower than Borosilicate (Pyrex) glass, which means that as it cools down, fused silica preserves its shape to a high degree of accuracy. Unlike German Equatorial mounts, there are no meridian flips to deal with you can image continuously from horizon to horizon if desired. The mass required to make a rigid Alt-Az mount is substantially less, leading to substantial cost savings. An Alt-Az telescope is also considerably more compact than its equatorial counterpart, allowing a larger telescope to fit in a smaller enclosure. An Alt-Az mount is inherently more stable than an equatorial mount since there is no cantilevered mass, nor are there any large protruding counterweights to create a dangerous hazard in a public observatory.

With direct-drive motors, high-resolution encoders, zero-backlash and no periodic error, the PW1000 sets a new standard in 1-meter class observatory telescopes.Īlt-Az mounts are the choice for most modern professional observatories. The dual Nasmyth ports allow two instruments to be installed simultaneously, and a computer-controlled M3 mirror allows either instrument to be remotely selected in seconds. Light-weighted optics are made of zero expansion fused silica materials for excellent thermal stability and maximum throughput. With a diffraction-limited 100mm image circle, the PW1000 is designed to excel at imaging on the largest format cameras available today. The PW1000 is a complete 1-meter observatory-class telescope featuring a direct drive altitude-azimuth (Alt-Az) mounting system designed and engineered by PlaneWave. With direct-drive motors, high-resolution encoders, zero-backlash and no periodic error, the PW1000 sets a new standard in 1-meter class observatory telescopes. With a diffraction-limited 100mm image circle, the PW1000 is designed to excel at imaging on the largest format CCD cameras available today.
