Meade 12" LX850-ACF (f/8) Advanced Coma-Free w/UHTC #1208-85-01. 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.
This 12" LX850 has 12" diameter f/8 ACF optics (focal length 2438mm) and 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 two 26 pound stainless steel counterweights, additional weights sold separately. LX800 mount shown in photo, LX850 mount similar.
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.
The New LX850™ with StarLock™.
The portable astro-imaging system that can be setup, aligned and imaging in less than thirty minutes.
Only from Meade.
Building on the foundation of the technologically revolutionary LX800, Meade engineers have taken the next step in astrophotographic evolution. We kept the same innovative concepts like Starlock™ fulltime automatic guiding and high-precision pointing, f/8 ACF OTAs with internal Crayford-style two-speed focuser and a portable precision German equatorial mount, but reengineered it to deliver more performance with less user effort.
Here is a brief list of a few of the changes and new features made to create the new LX850:
- NEW polished bronze worms in both RA and DEC drivers that deliver smooth motion with low periodic error.
- NEW larger roller bearings in both RA and DEC axes to better handle larger loads.
- NEW roller bearings in the RA and DEC clutch assemblies to allow freer motion with the clutches loosened for easier balancing.
- NEW one-piece 1 inch thick saddle plate with improved dove tail clamps, thicker OTA rail and radius blocks to reduce flexure between the OTA and mount.
- NEW alternative StarLock mounting position on ACF OTAs for virtually no flexure between StarLock and the primary optics.
- NEW StarLock software improvements to guide star selection, tracking/guiding accuracy, Ultra High Precision Pointing, and Drift Alignment.
- NEW StarLock automatic guide rate calibration which analyzes the sky conditions and sets the best possible guide rates for both RA and DEC.
Fast f/8 Advanced Coma-Free (ACF) optical systems on the 10", 12" and 14" OTAs. These optics produce wider, flatter fields with no coma for pinpoint stars out to the edge of larger imaging sensors or extreme wide angle eyepieces.
Internal Crayford-style primary mirror focusing system with a dual speed 7:1 focus control. Precise focus is a snap.
130mm 3-element, air-spaced apochromatic f/7 refractor with 3" Crayford-style 10:1 focuser. Beautifully machined and finished with case. Optional 3" field flattener available.
StarLock full-time automatic integrated guider provides computer-assisted drift alignment for refining polar alignment, finds and centers targets and then automatically locks onto a field star as faint as 11th magnitude for guiding. No separate computer, no guide star selection, no guide scope focus. Just set up your camera and image.
German Equatorial Mount made from machined aluminum and stainless steel with large bearing surfaces and roller bearings in both axes for an extremely solid and stable platform.
Internal cabling to prevent snags and tangles during your imaging sessions.
Precision machined 5.8" main gears with 225 teeth in both R.A. and DEC. with .68" polished bronze worms for very accurate movements and tracking.
1.75" diameter threaded stainless steel counterweight shaft with 26 lb. threaded stainless steel counterweights for easy and safe adjustments to telescope balance.
Sophisticated built-in computer for the most accurate control of the StarLock and other telescope systems.
AutoStar II hand control with over 144,000 object database to take you to almost any object imaginable at the push of the GoTo button. AutoStar II allows the user to setup and operate the LX850 in just the way you want.
Ultra-stable adjustable height tripod. Three inch diameter legs fold up for easy transport.
