Flattener / Reducer / Correctors

Flattener / Reducer / Correctors

Corrective optics are a very important component, especially in astrophotography. They turn almost every refractor, Newtonian or other telescope into an astrograph. They flatten the image field, shorten the focal length or correct system-related image errors.

The Svbony SV193 combines two essential functions for ambitious astrophotographers: focal length reduction and field flattening. With a reduction factor of 0.8, it shortens the effective focal length of the SV503 80mm f/7 from 560 mm to approximately 448 mm, enabling a wider field of view and shorter exposure times—ideal for deep-sky imaging.

Technical Features

  • Optical design: 3 elements in 3 groups, fully multi-coated for high light transmission and minimized reflections
  • Connection: 2″ barrel with M54x0.75 thread for cameras; compatible with full-frame sensors
  • Filter thread: Standard 2″ thread for integrating light pollution filters
  • Housing: Hard-anodized aluminum, lightweight and durable
  • Field flattening: Corrects spherical aberration and edge distortion for sharp star images across the entire field
