Takahashi Reducer/Flattener for Sky 90, FS-78, & FS-60C
Takahashi F/4.5 Reducer for SKY-90
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.
Takahashi Product Number: TFP0900

Is this flattener/reducer also compatible with the FC100DC?
No, this reducer will not result in a flat field with the FC-100DC. You will want to use the TKA1858 reducer for your scope: https://www.optcorp.com/takahashi-fc-76d-reducer-tka1858.html.
