Baader Filters OIII CMOS f/2 Highspeed 50.4mm

The Baader OIII CMOS f/2 Highspeed 50.4 mm is designed for astrophotographers with full-frame cameras. The filter is precisely matched to f/2 optics and keeps the OIII band stable at 500.7 nm so that the transmission does not shift in high-speed systems.

Application:

• For use in 50.4 mm filter holders and custom adapters
• Ideal for RASA 11″, Newton f/3, Epsilon
• Suitable for emission nebulae and narrow-band shots
