The highest priority during development of the Leica S lenses was image quality. Their sophisticated design features special grades of glass and aspherical surfaces rarely found in optics of this size. In addition, lenses manufactured to extremely narrow tolerances, with each lens centered by hand, guarantees superior quality and optical performance. The maximum performance of each lens is available even at full aperture setting, or when shooting from a distance or capturing close-up images. Vignetting, distortion and chromatic aberrations have been reduced to the point of imperceptibility, eliminating the need for quality-degrading image corrections and simplifying digital post-processing considerably. The newly developed S-bayonet mount ensures rapid and precise digital exchange of data and commands between the camera and lens. Precise, high-speed autofocus The autofocus developed by Leica for the S2 is based on a centrally positioned cross-hair sensor for high precision focusing. Each S lens has its own Leica-designed microprocessor for precise autofocus and iris diaphragm control. The integrated focusing drive is a proprietary Leica design that features silent gearing. All S lenses have a generous focus ring with just the right amount of drag, letting the photographer override the autofocus at any time. Rugged, durable design The camera's body is made of robust die-cast magnesium with a leather-grain finish for maximum grip. The S2 and all S lenses are extensively weatherproofed and can withstand exposure to rain and dust, and the USB and remote control ports feature rugged bayonet locks with strain relief. The S2 can also be supplied with a highly scratch-resistant LEICA S2-P sapphire glass display cover for the most extreme and demanding conditions. Dual shutter system The LEICA S2 allows photographers to choose the shutter system which best matches the task at hand. The S2 is equipped with a metal focal-plane shutter with the fastest shutter speed of 1/4000 of a second and a flash synch time of 1/125 of a second. Lenses of key focal lengths will be available in the future with integrated leaf shutters designed by Leica engineers that photographers can activate via the camera's main switch. The integrated leaf shutter allows flash units to be used at the fastest shutter speed of 1/500 second, giving photographers more options for suppressing unwanted ambient light. Several patents are pending for the Leica leaf shutter, which features an electronically-controlled drive guaranteeing reliable, fast exposure times and low energy consumption.

It has now been 20 years since Tele Vue designed the original 13mm Nagler eyepiece. From then on Tele Vue has always sought ways to obtain the largest possible true fields (i.e. longer focal length) while maintaining the basic Nagler concept; 82 degree apparent field with good correction to the edge. The previous Nagler versions were not conducive to scaling to longer focal lengths. A totally innovative design using four different exotic glass types (some larger than the 70mm Pronto objective!) in a 6 element configuration, opened the door to the largest true field possible in the Nagler eyepiece family. With fewer elements, Tele Vue also retained the high contrast achieved on the Radians and Nagler Type 4s. Although the sheer size and element shapes preclude using an "instadjust" eyeguard, the eye- relief is quite comfortable and the weight was actually kept below that of the 20mm Nagler Type 2! The true field is, however, more than 50% wider (or 2.35x the area). Tele Vue hopes the 31mm Nagler Type 5 gives you as much of a "spacewalk" jolt as the original 13mm Nagler did 20 years ago.

Concept: CCD cameras have challenged telescope optics beyond anything ever placed at the focal plane. Tele Vue knew it's APO objectives were up to the challenge, & with the proper tweaks would be extraordinary tools for the imager. With Tele Vue Imaging System (is) telescopes, they have refined their instruments & optional equipment beyond anything a CCD chip has seen.It started small (literally) in 2005 with the Tele Vue-60is & available Digital Micrometer Kit. Achieving critical acclaim with the 60is, Tele Vue was encouraged to further develop "is" telescopes & accessories to maximize aperture, real field coverage & performance, & to make the processes easier for the imager.For 25 years, Tele Vue has pushed the boundaries of APO refractors, & eyepieces, to the recognized pinnacle of performance. They were gratified but not surprised that Backyard Astronomer's Guide said of the NP101: "optics don't get any better than this." No wonder "Sky and Telescope" rated the NP101 tops & selected it as the test instrument for its landmark review of the SBIG STL-11000 CCD camera. The "is" versions of the Tele Vue- 60, 102i, NP101 & NP127 retain the exemplary wide field & planetary visual capability while adding new features to make imaging easier & more flexible.Tele Vue-NP101is Tele Vue-NP127is:Tele Vue was determined to make the NP series optically, mechanically, & functionally as perfect as possible for imaging up to 50mm diagonal chips with out penalty to its near ideal visual operation.How? By applying the developments created for the Tele Vue-60is to the new NP101is and NP127is & then going beyond. The NP101 (540mm, f/5.4, 4") & NP127 (660mm, f/5.2, 5") maintain their optical specifications yet with redesigned 4-element optical systems. Larger rear lens groups absolutely 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.In order to take full advantage of the larger lenses, a non-vignetting focuser was developed to prevent any restriction of the larger converging light cone. The draw tube has a 3" front aperture & 2.4" rear aperture. This new draw tube also permits quick change from visual to imaging operation & allows full camera rotation without focus change.In addition, it has the capability to correct for any residual focal plane tilt & accepts a "position stop" for Tele Vue's digital micrometer to allow repeatable focus measurement to 0.0001". To maintain squareness to the optical axis while changing camera orientation, the draw tube has 4 lock screws that tighten against a taper on the "imaging insert" ring. This insert is threaded to accept Tele Vue's new Imaging System accessories including large diameter extension tubes, optical accessories, & camera & CCD attachments, all with mating threads.
