Do you want to get more out of your Takahashi TOA-130S or TSA-120 refractor telescope? Now you can with the Takahashi TOA-35 Flattener. The TOA-130FN flattener is perfect for CCD imaging and extends over almost all CCD sensors. Now you can get the flat field you desire with no edge distortions. The Takahashi TOA-35 Flattener gives a generous 40mm image circle for all your general imaging applications.

The Takahashi TOA130FN field flattener was designed with the Tak TOA Triplet APO refractors in mind and works perfectly with all models of Takahahsi TSA-102S, TOA-130, and TOA-150 providing a 2.8°, 2.3° and 2.09° flat field image over a 40mm diameter circle respectively. This in turn corresponds almost perfectly to a 35mm image and provides those perfect, exact stellar images you demand from your astrophotography!

The Takahashi TOA130FN field flattener does just a little bit more, too. Use it with a 2" wide field eyepiece to provide a flat field! Like all Takahashi products, thoughtfulness in design shows right through with fully multi-coated optics, safety grooves and not one, but two thumbscrews to securely hold your accessories in place.
