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

• Supports ASCOM driver and NINA integration;
• 7 12V DC outputs, Regulated Interface and switch1-5 interfaces can be individually controlled on/off;
• The USB port can connect to guide cameras, planetary cameras, etc.; the DC port can connect to DSO cooled cameras, equatorial mounts, electronic focus controller, motorized filter wheels, and electronic field flatteners; and the RCA interface can connect to dew heaters;
• Real-time detection of ambient temperature and humidity to achieve automatic temperature control throughout the process. 

Note:  The recommended PWM value is around 80. When the temperature of the heating belt is 5 degrees higher than the dew point temperature, it will stop heating. When the temperature drops, it will automatically heat up.
