Takahashi FS serie

 

The FS refractor serie is the substitute of the old FC serie. As optical coating making progress to protect lens, Takahashi was able to put the fluorite lens in front of the doublet. Like this, a better color corection can be reach. The availables sizes 60, 78, 102, 128 and 152mm

FS 102 (1994 and 2005)

The origialversion came in 1994. In 2005, we can saw a new version, which name is FS 102 NSV (for New Short Version). This is the same doublet and the shorter tube allow using a bino viewer.
