TAKAHASHI TOA-35 REDUCER FOR TSA-120 & TOA-150B

The Takahashi TOA-35 Reducer for TSA-120 & TOA-150B is a 0.7x focal reducer for the TSA-120 & TOA-150B refractors. The TOA-35 reducer has an image circle of 44mm, making it suitable for use with full-frame sensors. The 0.7x reduction factor transforms the TSA-120 into a 635mm f/5.3 widefield astrograph and the TOA-150B into an highly corrected 775mm f/5.2 mid-field astrograph.

The TOA-35 Reducer consists of four lenses in three groups, with two low dispersion, high refractive elements for exceptional correction. When used with the TSA-120, the correction is 8 microns at the centre of the field and 12 microns at the edge. With the TOA-150B, the correction is an incredible 3 microns at the centre of the field and 6 microns at the edge.

The TOA-35 Reducer for TSA-120 & TOA-150B TKA32580B includes the CA Ring (TOA150) TKA32202 adapter, allowing an M54 x 0.75 connection to common imaging systems.
