Vixen Optics Focal Reducer for FL55SS Telescope

BH #VIRHD • MFR #37251
Vixen Optics Focal Reducer for FL55SS Telescope
Key Features
  • Use for Long Exposure Astrophotography
  • Reduces OTA's Focal Ratio to f/4.3
  • 3-Element/3-Group Lens Design
  • High-Transmission Multi-Coated Optics
This Vixen Optics Focal Reducer is purpose-built to speed up the focal ratio of the FL55SS telescope from an f/5.5 to an even faster f/4.3. Using the focal reducer during astrophotography with the optical tube allows you to use shorter exposure times without dimming the image, lowering image quality, or introducing additional signal noise. It has a 3-element/3-group lens design with high-transmission anti-reflection optical coatings to boost light transmission to over 98% to improve overall image brightness and sharpness. Not intended to be used by itself, it is designed to be used in combination with an additional accessory, such as a wide photo adapter 60DX, which is available separately.
