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.
Field corrector and focal reducer for compact 70 mm and 72 mm APO or ED refractors for astrophotography, for example TS 70 mm f/6 ED or TS SD Apo 72 mm f/6

The 1.0x image field corrector is designed for refractor telescopes with 60mm aperture and 360mm focal length and flattens the image field for astrophotography.
Designed for the TSMPT60 60mm f/6 ED refractor for optimal results.
Can be used on all 60mm f/6 refractors
Connection telescope side M54x0.75 male thread
Connection camera side M48x0.75 male thread
Working distance from camera thread to sensor is 55 mm - optimal for DSLR system and astro cameras

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
