![[W9152D] Svbony SV193 Faktor 0,8 Reducer/Flattener-Korrektor für SV503 80mm f/7](https://www.apm-telescopes.net/images/thumbs/0654992_w9152d-svbony-sv193-faktor-08-reducerflattener-korrektor-fur-sv503-80mm-f7_640.jpeg "[W9152D] Svbony SV193 Faktor 0,8 Reducer/Flattener-Korrektor für SV503 80mm f/7")
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

- 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
