New AudioStar Handbox

AudioStar with Astronomer Inside Standard on the LX90 and LT lines of telescopes. Here's why your customers will be excited to get this amazing new product. Only Meade Instruments' NEW AudioStar with Astronomer Inside does all this:

  • Look and listen as the Astronomer Inside guides you through the universe, describing, in detail, the objects you are seeing in the eyepiece. With over four hours of audio descriptions of astronomical objects including planets, stars, constellations, clusters, nebula, galaxies and more, the AudioStar brings astronomy to life. It's like having a professional astronomer standing next to you at the telescope.
  • The NEW AudioStar with Astronomer Inside takes you on a guided tour. Shows you the best objects in your sky from your location and time and then plays audio descriptions of those objects so you learn the details of what you are seeing.
  • The NEW AudioStar knows the sky so you don't have to. It controls the telescope to find and track any of over 30,000 celestial objects automatically.
  • The NEW AudioStar with Astronomer Inside and the intelligence integrated into these Meade Instruments' telescopes provides the user with all the experience and astronomical knowledge that a professional astronomer could offer.

This Meade 12" LX90-SC is a very large aperture telescope at a very attractive price. It is a great choice for both the serious amateur astronomer and the school or college observatory. Its standard equipment includes a GPS (Global Positioning Satellite) receiver and AudioStar computer takes the guesswork out of finding your way around the skies. It lets you locate dozens of deep space objects like a seasoned observer your first night out.

The UHTC multicoated optics of this 12" Meade provide 15% higher light transmission than a similar aperture scope with standard coatings. You'll see the difference when hunting the faint fuzzies at the far edges of the Universe and when doing serious long exposure astrophotography. If you have the dark skies to take full advantage of its immense light gathering capacity (two and a quarter times that of an 8" scope), or are willing to make the effort to transport this rather heavy scope to the dark sky site it needs for best performance, this 12" Meade is a scope that can keep you happily observing and photographing the wonders of the heavens for the rest of your life.

With two and a quarter times the light gathering capacity of an 8" scope (and 45% more than a 10") for a visual limiting magnitude of approximately 16, this scope's 12" optics give the Universe an astonishing depth, dimension, and grandeur at dark sky sites. Add to that the 15% additional light transmission afforded by the UHTC optics, and you have an exceptional scope for visual and photographic observing of the faint fuzzies beyond the solar system. With a photographic limiting magnitude of 19, you can photograph the sky in superlative detail (and with surprisingly short exposure times) by adding a few inexpensive accessories. If you plan on doing extensive deep space photography in the winter with your telescope, you'll appreciate the shorter exposure times provided by the extra 15% light transmission of its UHTC multicoated optics.

This 12" Meade scope will perform quite nicely on faint deep space objects such as galaxies and nebulae under mildly light-polluted suburban skies, if it is provided with a suitable light pollution filter. However, truly dark skies are essential if you want to take full advantage of this scope's very large aperture and superb optical performance. It's not a telescope that likes having its performance limited by a light-polluted suburban observing environment. But, if you have regular access to dark skies, the 12" LX90-SC may be just the right scope for you. It has all of the aperture and extra light-gathering you need to keep you busy observing and photographing for the rest of your life, with enough useful features to handle almost any observing and astrophotography chore you set for it . . . and a surprisingly reasonable price that won't break the bank.

Features of This Telescope:

  • Schmidt-Cassegrain optics: 12" aperture (3048mm focal length f/10). Fully-multicoated UHTC (Ultra High Transmission Coatings) optics with oversized primary mirror for the highest possible image brightness. Aluminum tube construction with glare-stop baffling. Guaranteed diffraction-limited performance.

  • Finderscope: 8 x 50mm straight-through achromatic design, with a 5 degree field of view and 12mm eye relief. It focuses by loosening the trim ring behind the objective lens cell, screwing the lens cell in or out to focus, and tightening the trim ring to lock in the correct focus.

  • Star diagonal: 1.25" 90 degree prism type.

  • Eyepiece: 1.25" 26mm Super Plossl (117x). The eyepiece field of view is 0.43deg. over 80% the diameter of the full Moon, for eye-filling lunar and deep space views.
Features of the Mount:
  • Fork mount/drive system: Die-cast aluminum drive base. Light-weight, but rigid, die-cast aluminum dual fork arms damp vibrations quickly. There is a carrying handle on each fork arm. The mount includes servo-controlled 12V DC slewing and tracking motors in both altitude and azimuth. The motors are powered by eight user-supplied C-cell batteries that fit into the drive base. An optional #RCXAC adapter is available to power the scope from 110-120 volt 60 Hz AC household current in your back yard to conserve battery life. High capacity rechargeable 12 VDC battery packs are also available.

  • Adjustable height tripod: The tripod is the same as the one used on Meade's premium 10" LX200 scopes, which has more than enough payload capacity to handle the 12" LX90. Its 2" diameter steel legs adjust the tripod height from 30" to 44". A single threaded rod with a large hand-tighten knob simultaneously holds the scope firmly on the tripod and locks the legs rigidly in the most stable position. The simple tripod/altazimuth mount configuration of the 12" LX90 makes setup reasonably easy. However, with a 60 pound optical tube/fork arms/drive base assembly to lift up onto the tripod, assembly is a task better suited to two people, rather than a single individual. One suitably motivated person can assemble the scope, but it is not easy. In addition to lifting the heavy scope on the tripod, you have to line up a hole in the base of the mount (that you can't see) with a hole in the top of the tripod (that you likewise can't see) in order to thread a rod through the tripod and into the drive base to lock the components together. One person centering and steadying the scope on the tripod while a second individual threads the rod into scope base makes assembly much easier and safer.

  • Audiostar computer: The LX90-SC's Autostar computer hand control plugs into the telescope's fork arm to permit a wide array of telescope options. First and foremost is its automatic go-to capability. The AudioStar computer can show you the planets and thousands of deep space objects the very first night you use your scope - even if you've never used a telescope before! At the push of a button, the LX90-SC will move at a fast 6.5 degree per second to any of the more than 30,000 deep sky and solar system objects in its database, then track it flawlessly across the sky while you observe at your leisure. There are standard solar, lunar, and sidereal tracking rates with 2000 precision-selected incremental rates that permit observatory-level precision in tracking the Moon and planets. The AudioStar includes a dual-axis drive corrector for long-exposure guided astrophotography.

  • AudioStar computer operation: Using the LX90-SC AudioStar computer is simplicity itself. Simply mount the scope on its tripod, turn it on, aim the scope North, and level the optical tube. The built-in 16-channel GPS receiver locks onto the network of orbiting GPS satellites to determine your observing location's latitude, longitude, date, and time. Using this information, the LX90-SC orients itself to the sky and slews at 6.5 degrees per second to the first of two alignment stars. If that star is not precisely centered in the finderscope or main scope optics, a touch or two on the AudioStar hand control's directional push buttons quickly centers it. Do the same with the second alignment star the scope moves to and you're ready to observe. That's it!

  • AudioStar Suite Software: This software package integrates the LX90-SC with your PC or laptop computer for an enhanced range of performance features. It includes a planetarium program with a database of 19,000,000 stars and deep space objects to display on your computer screen. Connect the scope to your computer using the supplied cable, click on any object in the sky map on your computer screen, and your LX90-SC automatically slews to that object. You can use it to control your telescope remotely via the Internet. "Talking Telescope" software (included) converts AudioStar text displays to synthesized speech through your computer speaker. And you can use all of the program's planetarium features for planning future observing sessions when nights are cloudy by automatically generating AudioStar Tours of favorite objects with a simple point and click.
