ZWO Clear Glass Filter D25

ZWO Clear Glass Filter D25: sensor protection without loss of image quality

This clear glass filter keeps dust, moisture, and scratches off the sensor of your ZWO ASI camera without reducing light transmission. With 95% transmittance and an anti-reflective coating, you won’t notice it in your images, while your sensor stays clean and dry during long nights.

On reflecting telescopes, this clear glass is sufficient as a sensor seal. For refractors, the ZWO IR-blocking variant in D25 format is the better choice because it also blocks infrared light and thus prevents focus shift.

Features

• 95% display for maximum brightness and contrast
• Protects the sensor from dust, moisture, and scratches
• M42 x 0.75 thread, directly fitting D25 cameras
• Easy to clean with an air blower or lens cloth
