The new Meade 10" LX850-ACF Telescope has new improvements in both astrophotographic and visual use. Among some of these improvements include wider and flatter fields, virtually eliminating coma for sharper views and images which is a major plus for professional and amateur astrophotographers, the StarLock dual imager as a full time guider for guiding improvements using the two sensor camera, as well as the Ultra Precision Pointing and Assisted Drift Alignment. Other less significant features include improved gear drives with lower periodic error, a GPS receiver and a 144,000 object database in the AutoStar II GOTO system. The newly designed mount now includes machined stainless steel construction to improve conditions for viewing and now has a 90 pound payload capacity. This means that it can accommodate quite large optical tubes designed for hard core astrophotography. Slewing and pointing accuracy has also been improved to as good as one arcminute due to the roller bears and stainless steel RA shafts. The new designed optical tube assembly includes a Crayford focuser with a two speed 7:1 reduction control.

Product Series

he LX850™ with StarLock™

A 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.


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.


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 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.
