Details
* 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.
