Takahashi 645 Reducer - 0.7X - TKA38580

The 645 Reducer from Takahashi is designed for the FSQ-106EDX4 and the FSQ-130ED. It will reduce the effective focal length in either scope by 0.7X, which gives you a wider field of view and also shortens exposure times when doing astrophotography. The Takahashi 645 Reducer is a great choice when pairing with a large sensor due to its 70mm image circle.

According to Takahashi, with the 645 0.7X Reducer installed, you'll get the following focal length, focal ratio, and image circle:

Installed on FSQ-106EDX4:

  • Effective Focal Length: 371 mm
  • Effective Focal Ratio: f/3.5
  • Resulting Image Circle: 70 mm
  • Installed on FSQ-130ED:

  • Effective Focal Length: 455 mm
  • Effective Focal Ratio: f/3.5
  • Resulting Image Circle: 70 mm
