Meade LX85 70mm f/5 Quadruplet ED APO Astrograph (OTA Only)
Key Features
  • 70mm Aperture Astrograph OTA
  • 350mm Focal Length, f/5 Focal Ratio
  • Apochromatic Quadruplet Lens System
  • FPL-53 Extremely Low Dispersion Glass
The LX85 70mm f/5 Quadruplet ED APO Astrograph from Meade Instruments is a purpose-built telescope for astrophotography and astro-imaging, with an imaging circle designed to completely cover the larger sensors of today's DSLR cameras. Optically it is designed with fully multi-coated FPL-53 extremely low-dispersion (ED) glass in a quadruplet apochromatic lens configuration that corrects for spherical and chromatic aberrations, astigmatism, and off-axis comas. This correction creates a wide flat field of view without distortion and removes the blue-tinted "halo" affect for true high-contrast color transmission.

The LX85 70mm f/5 Quadruplet ED APO Astrograph from Meade Instruments is a purpose-built telescope for astrophotography and astro-imaging, with an imaging circle designed to completely cover the larger sensors of today's DSLR cameras. Optically it is designed with fully multi-coated FPL-53 extremely low-dispersion (ED) glass in a quadruplet apochromatic lens configuration that corrects for spherical and chromatic aberrations, astigmatism, and off-axis comas. This correction creates a wide flat field of view without distortion and removes the blue-tinted "halo" affect for true high-contrast color transmission.

The OTA can be used for multiple astrophotography techniques, with a 42mm fully illuminated image circle that will cover a 35mm full frame sensor. Meade utilizes a precise dual-speed rack-and-pinion focusing mechanism that enables tack-sharp focusing with the ability to handle heavier loads versus other systems, such as a Crayford. To easily connect common size cameras, imaging rigs, and filter wheels, 42 and 48mm T-adapters are included; you just need to provide the camera and appropriate ring. While the astrograph is offered here without a mount or tripod for users that have a reliable support system, a set of mounting rings and a Vixen-style dovetail plate are included. For safe transport and storage, Meade includes a hard aluminum carrying case with a custom-cut foam lining.

Optical Performance

  • 70mm objective lens
  • 350mm focal length
  • Fast focal ratio of f/5 is ideal for astrophotography or imaging
  • Refractor-style optical design
  • FPL-53 extremely low-dispersion glass limits spherical and chromatic aberrations, astigmatism and off-axis comas
  • Quadruplet apochromatic lenses further correct chromatic and spherical aberrations for true color rendition without distortion across the entire field of view
  • Fully multi-coated optics maximize light transmission, while improving color, clarity, and contrast
  • Colors are faithfully rendered by eliminating the blue "halo" effect of chromatic aberrations
  • Resolution: 1.655 arcsec, Dawes' Limit
  • Retractable dew shield resists condensation build-up on the objective lens
  • Includes 48mm and 42mm T-adapters for connecting common DSLR/imaging systems and filter wheels

Focusing System

  • Optimized for imaging
  • Rack-and-pinion design is able to carry heavier loads without shifting or flexing versus Crayfords
  • 10:1 two-speed mechanism allows for precise focusing
  • 2.5" drawtube allows the use of larger accessories, and ensures full coverage of camera sensors without vignetting
  • Focuser lock knob locks the focuser in place for long-exposure astrophotography

Mounting

  • Optical tube assembly only - mount and tripod required for proper use
  • Vixen-style dovetail plate
  • Cradle-ring assembly allows the scope orientation to be adjusted to avoid interference with gear or accessories, or on mount configuration
  • Weight: 4.5 pounds

Carrying Case

  • Hard aluminum exterior with reinforced edges and corners
  • Hinged carry handles
  • Over-center latches pulls the lid down for maximum security
  • Custom-cut foam-lining protects OTA and accessories
