- 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 Temma II Mount handles a payload of up to 35 lbs.
- GoTo control can be accomplished via your PC
- 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 Mount:
The EM-200 Temma II is an accurate, precision-built GoTo German equatorial mount that provides a stable platform for payloads
of up to 40 pounds.
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.
Included in this package are an RS232C cable, ST-4 or ST-7 cable, shaft encoders, hand controller, power cord for both 12V and
24V operation, and software.
The new style EM-200 mounts include the ability for operation on 12v or 24v and feature high speed slewing at 350x [sidereal
rate] at 12v and 700x at 24v. 12V operation takes place with the use of the hand controller only. The mount will then function
just like the EM-200 USD model (no GoTo functions). However, with the use of the hand controller and your PC, you can operate with
12V or 24V (two 12V batteries connected in series). 12V will give you a slewing speed of up to 350X sidereal, and 24V will produce
slew speeds of up to 700X. Your PC is required to actuate the GoTo functions on this mount. A dual-axis hand controller and power
cable for 12V/220V battery connection is included.
