With features generally offered only on custom-manufactured professional instruments, this Meade LX200 fulfills the demanding requirements for an observatory-class telescope.
Professional-grade ACF optical system.
Continuing the tradition of the LX200 ACF optics, the 16" LX200 yields the superior imaging required in advanced applications, whether in planetary or deep-space, visual or CCD imaging, in astrophotography, or in photometry. And, with it's super-clear aspheric high-spectral transmission Borofloat glass, from Schott AG Germany, correcting plate, the 16" LX200-ACF may be used into the ultraviolet spectrail region as well. With Meade's Ultra-High Transmission Coatings (UHTC), the telescope's effective image-brightness aperture over the visible spectrum increases to more than 17". To keep your telescope in thermal equilibrium the optical tube is equiped with a cooling fan as well as a filtered exhaust vent.
Oversized fork mounting.
The massive 16" LX200-ACF fork system, cast in one continuous piece from one declination housing to the other, includes a total of four 80mm roller bearings in declination (two in each housing) and two roller bearings in right ascension (one each of 100mm and 150mm bearings in the RA housing). Usage of these precision roller bearings in the telescope's design permits the addition of substantial auxiliary equipment without the risk of strain on the mount. Large DC-servo motor-driven 11" worm gears on both axes yield theh smoothh, precision tracking and slewing required of a professional telescope.
4-speed Zero Image-Shift Microfocuser.
This high precision, ultra smooth focuser allows you to obtain an extremely accurate image focus. Perfect for astrophotography or during high power planetary observation. Focus is controlled through the existing Autostar II handbox of the telescope. The microfocuser securely mounts to a thread-on type adapter (included) to the rear of your telescope. The diagonal or camera (not included) then inserts into the microfocuser which has approximately 1/2 inch of travel. Coarse focus is achieved conventionally through the telescopes focus knob. The Microfocuser is then used to achieve a more precisely focused image via the keypad, without image shift or shake.
Supergiant Field Tripod and Permanent Piers.
The 16" LX200-ACF is offered with a choice of tripod or piers, each suitable to specific user applications.
Supergiant Field Tripod. Supplied with the Supergiant Field Tripod, the 16" LX200-ACF is remarkably field transportable for an instrument of its aperture and specifications. The telescope is manufactured in four basic modules: optical tube assembly with declination housing attached, fork arm system, drive base, and field tripod. As such, the telescope can be readily transported and set-up in the field by 2 adults in about 10 minutes. The extremely strong and rigid tripod assembly, incorporating 4" diameter steel tripod legs, results in virtually no compromise in telescope stability when compared to a permanent pier system.
Placed atop the Supergiant Field Tripod, the 16" LX200-ACF operates in altazimuth mode. For visual observing, or for CCD astrophotography with exposures not exceeding 4 to 5 minutes, no additional equipment is required. However, during longer periods of imaging or photography, field rotation, an effect inherent to any altazimuth-mounted telescope, becomes noticeable. The result of such field rotation is the apparent rotation of stars at the outer edge of the field relative to the centrally-located star, even if the exposure is perfectly guided. This effect can be cancelled out completely by adding the optional Meade Field De-rotater.
Permanent Altazimuth Pier. For observatory applications the 16" LX200-ACF may be ordered with the permanent altazimuth pier, a mounting system that allows for comfortable, readily accessible eyepiece positions and is ideal when the telescope needs to be housed in the minimum amount of space.
Permanent Equatorial Pier. If auxiliary cameras or other long-exposure imaging devices are to be used with the telescope, then the equatorial pier is what you need. When mounted in the equatorial mode, there is no field rotation in either the main telescope or in any auxiliary, piggybacked instruments. All permanent equatorial peirs are custom-manufactured to match the latitude of the specified observing site.
