The LX850™ with StarLock™

Meade Instruments have a strong historical presence in the optics industry with many legendary products that remain phenomenal even in today’s standards. Leading the pack is the new, advanced LX850 with StarLock that boasts an extensive list of desirable and ground-breaking features that caters for the most discriminating needs of deep-sky observers and astrophotographers.

Equipped with StarLock dual imager integrated full time guider, Ultra Precision Pointing and Assisted Drift Alignment, 5.8″ 225 tooth polished bronze worm/gear drives with low periodic error, internal cable routing, GPS receiver, AutoStar II GOTO system with over 144,000 object library, heavy-duty adjustable height tripod with anti-vibration pads, Universal AC Adapter, Meade Zero Image Shift Electronic Micro-Focuser, telescope to computer USB cable and AutoStar Suite software, this scope places Meade miles ahead of its leading competitor.

Advanced Coma-Free

The LX850 series takes advantage of Meade’s Advanced Coma-Free (ACF) optics which puts a professional optical system within reach of aspiring astronomers everywhere. Nearly every observatory reflector in the world uses an aplanatic (coma-free) optical system like the Ritchey-Chrétien (RC), including NASA’s Hubble Space Telescope. Now you can own optics similar to what the professionals use.

The super fast system produces a wider, flatter field with no coma for pinpoint stars out to the edge of larger imaging sensors and extreme wide angle eyepieces. All of which is greatly desired by discerning amateur astronomers, astro-photographers and professional observatories alike. This patented system also reduces the astigmatism and eliminates diffraction spikes found in classical RC designs.


Aligning your scope is a chore for most observers but is unfortunately an absolute necessary process if you wish to observe for longer periods of time. With the revoluntary StarLock technology, this is no longer your concern. The the scope will automatically find and track the object so you only need to focus on the enjoyable aspects of astronomical viewing. StarLock achieves this by using an 80mm f/5 optic and two camera sensor system to provide computer assisted polar alignment using the drift method. Once aligned, StarLock will continue its job on its own – it will guide the mount in real time and automatically programs periodic error correction, leavingt you with incredibly precise tracking (up to 1 arcsecond) and and with the capability of guiding on stars as faint as 11th magnitude.

Heavy Duty Mount

The standards put forth by Meade for high-quality, no short-cut materials are evidently through-the-roof high to say the least. The LX850 mount is perfectly crafted out of machined stainless steel and aircraft grade aluminum for an overwhelmingly generous 90lb payload capacity and impeccable smooth movement and precise tracking of one arc minute. The mounts also incoporate precision roller bearings on each axis, a 1.75 stainless steel RA shaft, 5.8″ main gears, fine manual adjustment controls on both axis, illuminated reticle output port. The requirements for the mount to withstand such demands is monsterous. The mount’s main body weighs 55 pounds and the two stainless counterweights weigh 26lb each. The mount also comes with a fully height adjustable (29 to 45″) tripod with massive 3″ diameter legs for rock steady performance. The tripod weighs 36 pounds.

High Quality Accessories

The LX850 Series comes fully equipped with a Meade Series 5000 2″ diagonal prism featuring enhanced 99% reflectivity, Series 5000 HD-60 25mm eyepiece, and 8×50 viewfinder with quick release bracket. Also includes bracket for alternate OTA mounting of StarLock if desired.

Product carries full three year Australian warranty.
