Product Description

The Meade 10" LX200-ACF catadioptric telescope has Advanced Coma-Free optics to bring the astronomical image quality of a professional observatory to your back yard, at a down-to-earth price. It has a coma-free field similar to that of the Ritchey-Chrétien design optics used in most professional observatory telescopes and the Hubble Space Telescope, but at a fraction the cost of a true Ritchey-Chrétien of similar aperture.

Its UHTC optics give you 15% higher light transmission than ordinary single layer optical coatings for brighter images and shorter exposure times.

If you have the dark skies to take full advantage of its considerable light gathering capacity (57% more than an 8" scope), this is a telescope that can keep you happily observing and photographing for the rest of your life. But, if your neighbor's lights make your back yard not quite the dark sky site you'd like, this 10" scope is still portable enough to make taking it to a dark sky site very practical.

No matter what you're looking for in your dream scope, the highly-transportable 10" LX200-ACF with Advanced Coma-Free UHTC optics has all the useful features you need to cater to virtually every observing need you might have.

This Telescope's Optical System . . .

Advanced Coma-Free catadioptric designed to emulate the optical performance of a Ritchey-Chrétien telescope: 10" aperture catadioptric (2500mm focal length f/10). Fully multicoated UHTC (Ultra High Transmission Coatings) optics with oversized primary mirror for brighter field edge illumination. Aluminum tube construction with glare-stop baffling and mirror lock. Guaranteed diffraction-limited performance with a flatter field edge-to-edge than other commercially-available catadioptric optical systems. For more details, click on the "LX200-ACF UHTC optics" icon in the support tab above.

Finderscope: 8 x 50mm straight-through achromatic design, with a 5° field of view and 12mm eye relief.

Star diagonal: 1.25" multicoated prism type.

Eyepiece: 1.25" 26mm Series 4000 Super Plössl (96x). The eyepiece field of view is 0.52° (a hair larger than the full Moon), for expansive lunar and deep space views.
This Telescope's Mount . . .

Fork mount/drive system: Die-cast aluminum drive base. Dual die-cast aluminum fork arms support the optical tube. The mount includes servo-controlled 12VDC slewing and tracking motors in both altitude and azimuth. The motors are powered by eight user-supplied C-cell batteries that fit into the fork arms. Optional adapters (with 25' cords) are available to power the scope from 110-120 volt 60 Hz AC household current in your back yard to conserve battery life, or to power the scope from your car's cigarette lighter plug or a rechargeable battery for extended use in the field. For more details, click on the "LX200 mount" icon in the support tab above.

GPS/AutoStar computer: A 16-channel GPS (global positioning satellite) receiver is built into the top of the telescope's left fork arm. The GPS receiver, in conjunction with a built-in electronic compass and AutoStar computer control, automatically aligns the scope on the sky so that the AutoStar computer can locate for you the more than 145,000 stars and objects in its memory.

In addition to quickly and automatically moving the scope to any desired object with an accuracy typically in the two arc minute range, and flawlessly tracking the object while you observe at your leisure, the AutoStar computer provides numerous visual, tracking, and photographic tools and functions to make your observing easier and more enjoyable.

Unique "Smart Mount" technology can constantly improve the already high pointing accuracy of the telescope with every object that you center precisely and synchronize on during a night's observing. For more details on these features, click on the "LX200 computer" icon in the support tab above.

Adjustable height tripod: The tripod adjusts from 30" to 44" and damps vibrations quickly. It has 2" diameter steel legs, with a center leg brace for rigidity. Three 1.25" diameter holes in the leg brace can hold eyepieces while observing. 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.

AutoStar Software Suite: This standard equipment software package is designed to integrate the telescope with your Windows-based PC or laptop computer for an enhanced range of performance features. The AutoStar Software Suite includes a planetarium program with a database of 19,000,000 stars and deep space objects for display on your computer screen. It includes all the standard planetarium program features for stand-alone use when nights are cloudy. In addition, it contains programs for controlling the telescope from your laptop or PC.

What can you see through an 10" LX200-ACF with Advanced Coma-Free UHTC optics?

With 57% more light gathering capability than an 8" scope, this scope's 10" coma-free flat-field optics give the Universe a visual and photographic sharpness and grandeur at dark sky sites that no smaller scope can approach - no matter how good that smaller scope might be. And the multicoatings of the UHTC optics group produce images that are 15% brighter than you'll see with a conventionally coated scope!

The Orion Nebula shows an extension and subtlety of feature never visible through a smaller scope, particularly when you use a narrow band light pollution filter to increase the contrast of the fainter segments. Orion's Trapezium stars A and C reveal their faint 11th magnitude visual binary companions. Nebular wisps and fragments such as the Veil show markedly greater extent than with any smaller scope.

Faint galaxies and planetary nebulas, barely visible blurs in smaller scopes, start to reveal their structure in detail. Densely packed globular clusters are typically resolved to their core. Open clusters show stars that are sharp and point-like all the way across the field. Small storm cells in Jupiter's belts, plus tantalizing hints of surface details on its moons, can be seen under good seeing conditions, as can occasional dust storms on Mars. Cold and distant Pluto, a faint magnitude 13.9 speck, can be glimpsed making its lonely way across the skies. And, with a photographic limiting magnitude of 17, all of it can be photographed in detail (with surprisingly short exposure times) by adding a few inexpensive accessories.

The altazimuth drive of the LX200-ACF is more than accurate enough for piggyback, lunar, and planetary DSLR photos and much CCD imaging. However, field rotation causes stars at the corners of an image to streak during exposures longer than five minutes if an equatorial wedge isn't used to align the scope on the celestial pole. So, if you plan on doing deep space photography, you'll need to add an optional #2575 X-wedge to the 10" LX200-ACF.

This 10" scope will perform adequately on faint deep space objects such as galaxies and nebulas under mildly light-polluted suburban skies, if provided with the proper light pollution filter. However, it is at a remote site with truly dark and steady skies that you'll best be able to take full advantage of its large aperture, and superb optical performance. This is not a scope that's happy staying in a light-polluted city or suburban observing environment.

If you have regular access to dark skies, and the size and weight of the scope (a 63 lb. optical tube to lift up onto the tripod) doesn't daunt you, the 10" LX200-ACF with Advanced Coma-Free UHTC optics may be the perfect scope for you, particularly if you're serious about deep space observing and astrophotography. It has all the aperture and light transmission 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 astrophotographic chore you set for it . . . and a price that won't break the bank.

Although i was thrilled to have this scope, as it looked beautiful, I never really enjoyed the views through it. They were always hazy and never sharp or bright enough. I also had a 16” Lightbridge and preferred that way more. Although the go-to function is great, but the setup isn’t. I think these setups are more for astrophotography than they are for star hopping. Over all I didn’t like my experience with this telescope. (Posted on 11/21/2018)

I have owned this mount for several years and It's amazing to watch it operate. The goto's are spot on and so is the tracking when I image with it. The views are really good and sharp with lots of detail. This is the most amazing telescope I have ever owned, and it's easy to operate. (Posted on 10/6/2018)

I purchased my LX200ACF because I wanted a large aperture SCT. I am very pleased with my choice. The quality of the optics is superb with a flat field across the entire field of view. The UHTC coatings really bring out the contrast. The mount is easy to operate and the goto's are dead on. It's neat to watch the automatic leveling and north finding procedure, and aligning the mount is easy. At first I was worried about having to set it up each night because of its weight and size, but after about the 3rd time I was already use to it. There are nice big handles to make carrying it easy. This is definitely a telescope that I will be using for many years to come.
