Product description

• Meade LX65 6" f/10 ACF Catadioptric Telescope (OTA only) Formerly reserved for larger-aperture near-research-grade optical tubes, the Meade Instruments LX65 6" f/10 ACF Catadioptric Telescope is built with an Advanced Coma-Free (ACF) catadioptric-variant optical path to reduce color fringing and off-axis comas and to enable it to clearly resolve dim deep-sky objects and easily split binary stars with tack-sharp clarity. Complementing the ACF system is Meade's Ultra-High Transmission Coatings (UHTC) system that improves light transmission through the entire light path across the whole visible spectrum. A combination of high-transmittance lens coatings and highly reflective mirror coatings boosts image brightness, while minimizing internal and external light loss and diffraction.The LX65 is equipped with a Vixen-style dovetail rail that makes it compatible with a wide variety of alt-azimuth, equatorial, and GoTo mounts of all kinds by virtually every mount manufacturer in the world. This version comes with a 26mm Super Plossl eyepiece that produces a relatively low 59x, a 90° star diagonal, and a red dot finder.
  Optical Tube Assembly
  • • 152mm (6") aperture gathers enough light for viewing within the solar system as well as deep-sky objects without adding excessive weight and bulk, to maintain its portability
    • Moderate f/10 focal ratio requires longer exposure times for astrophotography
    • Long 1524mm focal length provides a high magnification potential
    • Catadioptric light path produces long effective focal lengths in a small OTA to make it powerful, yet easier to store, transport, and set up
    • Advanced Coma-Free (ACF) optical design corrects astigmatism and off-axis comas better than similar Cassegrain configurations
    • Single-speed internal focusing mechanism with 1.25" eyepiece/accessory holder
  Optical Technologies
  • Advanced Coma-Free System:
    • Reduces off-axis comas and astigmatism for sharper images
    • Eliminates diffraction spikes for better resolution
    • Aplanatic design produces flat, distortion-free images across the field of view—especially at the edges
    Ultra-High Transmission Coatings (UHTC):
    • All corrector plate and mirror surfaces are fully multi-coated
    • Engineered to optimize visual, photographic, and CCD imaging
    • Improve light transmission across the entire visible spectrum through the optical path
    • Corrector plate coatings made up of multiple layers of aluminum oxide (Al2O3), titanium dioxide (TiO2), and magnesium fluoride (MgF2)
    • Mirror coatings consist of aluminum with multi-layer coatings of titanium dioxide (TiO2) and silicon dioxide (SiO2)
  Mounting
  • • Optical tube assembly (OTA) only. Mount and tripod required for proper use
    • Vixen-style dovetail plate is compatible with a wide variety of mounts
    • OTA weight: 9.2 pounds
  Included Accessories
  • Eyepiece:
    • 1.25"-diameter barrel
    • 26mm focal length produces a low 59x power for viewing the Moon and planets, and for wide-field deep-sky use
    • Accepts most optional 1.25" astronomical filters to enhance views
    • Fold-down rubber eyecup
    Diagonal:
    • Star diagonal corrects view horizontally, but not vertically
    • 1.25" nosepiece and eyepiece holder
    Finder:
    • Unmagnified view ensures a wide field of view for easier alignment and faster star-hopping navigation
    • Multiple intensity levels ensure reticle visibility without affecting night-adjusted vision

• Meade LX65 GoTo Mount & Tripod Designed as a mid-level platform for small to medium optical tube assemblies (OTAs) of all types, the Meade Instruments LX65 GoTo Mount & Tripod features a motorized single-arm fork mount that is designed for portability and versatility. It is equipped with two Vixen-style dovetail saddles that allow you to mount an OTA on the primary and mount a secondary OTA or camera rig on an outside saddle. The mount has an integrated handle to make setup and breakdown easier and safer, and a battery compartment for the eight C-cell batteries required to run it and the controller. A stainless steel tripod with a center leg lock that improves stability and dampens vibrations supports the mount and OTA.The brain of the LX65 is the venerable AudioStar computer controller. Equipped with a database of over 30,000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog, it can also be programmed with custom user-defined objects. Its intuitive menu-driven user interface provides the power to observe the heavens with ease, especially with features such as guided tours, extended information on popular objects, and multiple alignment options. This updated version of the AudioStar has an integrated speaker so you can listen to a narration about what you are looking at without having to divert your eye or attention from the eyepiece, for added enjoyment.
  Mount
  • • Motorized single-arm fork
    • Controlled through the AudioStar controller

    • Secondary Vixen-style dovetail saddle enables dual-mounting of a smaller OTA, guidescope, imaging rig, or wide-field DSLR. 7-pound payload capacity
    • Integrated handle improves security when carrying to observation site and during setup and breakdown
    • Runs on eight user-supplied C-cell batteries or an external 12 VDC power source
    • 15-pound payload capacity enables the use of small to medium optical tubes of all designs plus accessories
