Meade LX850 ACF with StarLock

Smarter Telescope System. Only from Meade.
Drawing on over 40 years of experience and innovation, Meade instruments introduces the latest in a long line of advanced astronomical products: the LX850. Using revolutionary new technology, every aspect of this amazing telescope system has been designed to deliver the new standard in astrophotographic and visual performance.

Faster, Sharper Optical System
The LX850 employs a fast f/8 ACF optical system with high-contrast baffling that assures crisp, pinpoint imaging to the very edge of the field. The all-new OTA features an internal Crayford-style, zero image-shift focusing system with a two-speed, 7:1 control.

Precision Machined, Solid German Equatorial Mount
Constructed of machined stainless steel and aircraft grade aluminum, the LX850 mount presents a rock-solid platform with precision roller bearings on both axes and a 1.75" stainless steel R.A. shaft. Its .68" diameter brass worms and 5.8" diameter, 225-tooth aluminum gears deliver smooth, precise movement with up to a 90 pound instrument load. A fully-computerized GoTo mount with GPS, the LX850 comes with a database of over 144,000 objects. All this set atop a new super-stable tripod.

StarLock ƒ__ Full-Time Automatic Guiding
StarLock is the revolutionary new technology that makes target acquisition on your imaging sensor and accurate guiding during exposures completely automatic. StarLock uses an 80mm f/5 optic and a super wide-angle lens in a two camera system that automatically finds your target in high-precision, immediately captures a field star as dim as 11th magnitude and then guides to an accuracy of one arcsecond. There's no need for a separate guide or computer and the StarLock requires no user focusing or guide star selection. StarLock automatically programs periodic error correction and then corrects for any other errors down to virtually zero.

With the combination of the finest optics, a robust German equatorial mount and the revolutionary StarLock system, the LX850 is the smartest and most complete astro-imaging solution available.

Meade LX850-ACF (f/8) Advanced Coma-Free w/UHTC from 10" to 14".
Meade Instruments proudly introduces the new standard in astrophotograhic and visual performance, the LX850. The fast f/8 Advanced Coma Free optical 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. Includes 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.

Features top of the line Meade Advanced Coma Free (ACF) optical design offering the coma-free pinpoint star images and flatter image fields greatly desired by discerning amateur astronomers, astrophotographers and professional observatories alike. This patented system also reduces the astigmatism and eliminates diffraction spikes found in classical RC designs. Optical tube aperture sizes start at 10" up to 14".

Ultra-High Transmission Coatings (UHTC) for maximum image brightness and contrast. The all new OTA includes an internal Crayford style zero image shift focusing system with two speed, 7:1 reduction control.

Includes StarLock- the revolutionary new technology that makes target acquisition on your imaging sensor and accurate guiding during exposures completely automatic. With Meade's exclusive LightSwitch technology at its core, StarLock uses an 80mm f/5 optic and two camera sensor system to provide computer assisted polar alignment using the drift method. Once aligned the StarLock is guiding the mount in real time, and even automatically programs periodic error correction, achieving a guiding accuracy of up to 1 arcsecond in good seeing and with the capability of guiding on stars as faint as 11th magnitude.

The LX850 mount, constructed of machined stainless steel and aircraft grade aluminum is a rock solid platform for the most demanding applications, with a 90 pound payload capacity and pointing accuracy as good as one arcminute. Features include 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. Mount main body weight is 55 pounds. The fully height adjustable (29 to 45") tripod features massive 3" diameter legs for rock steady performance and weighs 36 pounds. Includes three 26 pound stainless steel counterweights, additional weights sold separately.

Telescope comes fully equipped with a Meade Series 5000 2" diagonal prism featuring enhanced 99% reflectivity, Series 5000 HD-60 25mm eyepiece, and 8x50 viewfinder with quick release bracket. Also includes bracket for alternate OTA mounting of StarLock if desired. Product carries full one year Meade factory limited warranty.
