Takahashi - Reducer/Flattener for Sky 90, FS-78, & FS-60C

    * The Takahashi F/4.5 Reducer was designed for the Takahashi Sky 90II.
    * Also compatible with Takahashi FS-78 and Takahashi 60C refractors, too.
    * The Takahashi F/4.5 Reducer takes the focal ratio of the Sky 90 down to f/4.5 for wide-field photographic use.
    * Also performs as a field corrector for perfect image flatness for large sensor equipment. 

The Takahashi F/4.5 Reducer-Flattener was designed for the Sky 90II, but it also works well with the Takahashi FS-78 and FS-60C
model refractor telescopes, too. Now you can move the focal ratio of the Sky 90 down to f/4.5 for wide-field photographic use.

What's more, the he Takahashi F/4.5 Reducer-Flattener also acts as a field corrector. This means perfect flatness for imagers
equipped with large sensors on their equipment.
