Takahashi TOA-130S Ortho APO Refractor on EM-200 USD III Mount


Takahashi TOA-130S 5.1" Ortho APO Refractor Telescope with EM-200 USD III Mount

  • 130mm f/7.7 triplet Ortho APO is Takahashi's newest design.
  • Compact design sports 32" tube with lens shade retracted
  • Includes classic 2.7" focuser
  • EM-200 USD III Mount handles a payload of up to 35 lbs.
  • High precision construction results in periodic error less than +/- 5 arc seconds
  • Includes built-in polar finder with adjustable illuminator.
  • Includes SE-L wooden tripod with Shimano Clamps.


The TOA-130 is the first of Takahashi's newest optical design: The Ortho-Apochromat. This 21st century innovation employs a newly designed triplet using special elements to produce the highest order of color correction and is packaged in a short 32” tube with the lens shade retracted.

This instrument is offered here with the classic 2.7” focuser. For those wanting to use a medium format camera, we also offer a deluxe 4” focuser with built �"in camera angle adjuster.

The high order of color correction of the Ortho-Apochromat Series produces images with saturated color and, thanks to the numerous knife-edged baffles, it also displays an image with amazing contrast.

The TOA-130 is perfect for visual, CCD and classic astrophotography. The f/7.7 focal ratio with a 1000mm focal length is long enough (using the optional LE-ED 2.8mm Takahashi ocular, for instance) for high magnification observations of the Moon and planets and yet will produce a 2.5�° field at 20x when used with the optionalTakahashi flat field LE-50 2 “ ocular.

Ample back focus, over 200mm from the rear cell, has been designed into the system to permit the user to use a variety of CCD cameras, color filter wheels and electronic focusers or film cameras.

The EM-200 USD III is an accurate, precision-built German equatorial mount that provides a stable platform for payloads of up to 40 pounds. It is an ideal mount for any type telescope, be it a refractor, reflector, or cassegrain.

The modern aesthetic design of the EM-200 is highly attractive as well as beautifully functional. The RA and DEC stepper motors are fully integrated into the mounting,and the high precision design and construction provides cyclic errors lower than +/- 5 arc seconds.

The integrated polar alignment telescope has an illuminated reticule which can be dimmed to suit the user or observing conditions. In conjunction with the precision altitude and azimuth adjusters, this will typically give polar alignment accuracy within 2 minutes of arc of the celestial pole.

Improvements (EM-200 vs EM-200 USD III) include the ability for operation on 12v (manual operation via hand controller or remote operation with Temma upgrade and a PC) or 24v (remote operation via a PC with the addition of the Temma upgrade). These new mounts feature high speed slewing at 300x [sidereal rate] at 12v and 700x at 24v. A hand controller and power cable for 12V/220V battery connection is included.
