Product Description
TeleVue NP101is Refracting Telescope OTA NPI-4057
TeleVue's NP101is Refracting Telescope has pushed the boundaries of APO refractors once again. This "is" version retains the exemplary wide field and planetary visual cabability while adding new features to make imaging easier and more flexible. By applying the already well craft features of the TeleVue 60is to the new NP101is, this refracting scope operates as perfect as possible for imaging up to 50mm diagonal chips without penalty to its near ideal visual operation.
The NP101is maintains optical specifications but are redesigned with 4-element optical systems. Using larger lens groups helps minimize vignetting in formats up to 50mm diagonal. For these large chips an optional field corrector was developed so the corners of the newly brightened edges would virtually be as perfect as the center of the field. TeleVue developed a larger draw tube and focuser having a 3" front aperature and 2.4" rear aperture. This feature helps eliminate any restriction of the larger diameter converging light cone. Also, the new draw tube permits quick change from visual to imaging operation. This allows full camera rotation without focus change. The draw tube has four lock screw that tighten against a taper on the "imaging insert" ring which help maintain squareness to the optical axis when changing camera orientation.
The 10:1 dual speed focuser customer designed by Starlight Instruments provides extremely sensitive focus adjustment, measurable with the optional Digital Micrometer Kit to better than 1/10,000". Permitting electronic motor control of the focusing process is possible with the optional Focusmate Driver. This driver has an adjustable speed and direction push-buttons. Just one simple tap of the button permits vibration-free focusing steps as small as approximately 0.0005". The Focusmate Driver can be remotely compter controlled with optional Focusmaster Com
