TOA-35 0.7x Reducer new!
Takahashi has designed
a high performance TOA-35 reducer for the TOA-130, TOA-150 and TSA-102/120
with a magnification of 0.7x
The ideal design
for a reducer is its ability to reduce the f-stop while flattening the
field and controlling chromatic aberration. The TOA-35 0.7x reducer
is configured with 4-elements in three groups and uses two low dispersion,
high refractive index glass , while reducing the focal length by a factor
The TOA-35 reducer produces 3-micron stars in the center of the field
and 6-micron stars at the edge with a very flat field. There is also
an improvement in the color correction when used with the TOA-130/150.
This high performance
optical system produces images that will be flat, sharp and highly corrected
for color. When used with the TSA Series the image is 8-microns in the
center and 12-microns at the edge.
The TOA-35 Reducer is available in two models: the 130 model is designed
to work with the TOA-130 and the 150 model is designed to work with
the TOA-150, the TSA-120 and TSA-102. Each model is supplied as a set
that includes the reducer and a wide mount Ø55mm adapter to attach
the reducer to the camera that is used.
