Takahashi TS refractors serie
The TS are the first serie of telescopes produced by Takahashi. It's difficult to have informations about these telescopes, because, we can found several telescopes under the same name.
TS 50
We can found 2 telescopes under the "TS 50" name:
in 1971, an achromatic
doublet at f/14 (f=700mm)
in 1977, another achromatic doublet at f/10 (f=500mm)
TS 65
in 1969, an
achromatic doublet at f/14 (f=910mm). It's the first
Takahashi Telescope!
in 1970, a triplet at f/15.4 (f=1000).
in 1972, an
apochromatique triplet at f/7.7 (f=500mm)
in 1976, an achromatic doublet at f/12.3 (f=800mm)
The first Tak ! | The First Tak ! | The 1970 at F/15.4 | The 1972 triplet f/7.7 | in 1979, the triplet f/7.7with P2Z mount |
TS 80
in 1970, an air spaced triplet, f/15 (f=1200mm).
TS 90
We can found 4 telescopes under the "TS 90" name:
1977, a fluorite
triplet at f/11.1 (f=1000mm) It's the first fluorite
Takahashi telescope!
1978, a triplet at f/13.3 (f=1200)
1978, an achromatic doublet at f/11.1 (f=1000mm)
1979, an achromatic doublet at f/13.3(f=1200)
