Special Order Item
Takahashi TOA-130S Kit, 5.1" Diameter, Ortho MC APO Triplet Refractor Telescope Optical Tube with Lens Shade & 2.7" Focuser, TSA0130
The Takahashi refractor, the triplet TOA-130, is the first of the Ortho-Apochromat Series. This 21st century innovation employs a newly designed triplet using special elements to produce the highest order of color correction, hence the name Ortho-Apochromat and is packaged in a short 32 tube with the lens shade retracted.
This instrument is offered with the classic 2.7 focuser (Model # TOA-130S) . For those wanting to use a medium format camera, Takahashi offers a deluxe 4 focuser (Model # TOA-130N) with built in camera angle adjuster.
This focuser, coupled with the (optional) dedicated flattener, will produce a fully illuminated 70mm circle with a usable 92mm diameter.
The high order of color correction of the Ortho-Apochromat Series produces images with saturated color and thanks to the numerous knife-edged baffles, an image with amazing contrast.
The TOA-130 is perfect for visual, CCD and photo imaging. The f/7.7 focal ratio with a 1000mm focal length is long enough, using the LE-ED 2.8mm Takahashi ocular, (not included) for high magnification observations of the Moon and planets and yet will produce a 2.5 degree field at 20x when used with the Takahashi flat field LE-50 2 ocular (not included) .
Ample back focus, over 200mm from the rear cell, has been designed in to permit the user to use a variety of CCD cameras, color filter wheels and electronic focusers or film cameras.
