Baader Filters OIII CMOS f/2 Highspeed 65x65mm

The Baader OIII CMOS f/2 Highspeed 65x65mm is designed for astrophotographers working with large sensors or observatory-class telescopes. The coating is precisely matched to f/2 systems so that the 500.7 nm transmission remains stable even at extreme light cones.

The square design provides maximum image coverage without vignetting, while the multilayer hard coating is reflection-free and moisture-resistant.

Application:

• Observatories and professional setups
• f/2 optics with large image sensors
• Deep-sky shots of OIII emission regions
