Astronomik ProPlanet IR-Pass Clip Filter

This filter blocks visible light and only allows infrared wavelengths longer than 807nm to reach your sensor. By doing this, it significantly reduces the blurring effect caused by atmospheric turbulence, which helps you capture much sharper, more detailed images of the moon and planets.

It is specifically designed for the Pentax K-1 and K-1 Mark II. Because the clip-in mechanism is precision-engineered for the internal dimensions of these specific bodies, it will not fit other Pentax models.

No modifications are required. The filter features a clip-in design that snaps securely into the camera body, allowing you to install or remove it quickly without any tools.

Yes, it is quite effective for daylight imaging. By blocking visible light, it darkens the sky background, which can create unique, high-contrast images of the sun or distant landscapes.

Not at all. The filter sits behind the lens mount, so it does not interfere with the mechanical or electronic functions of your lenses. You will retain full control over focus and aperture settings.

Yes, it acts as a protective barrier. By sitting in front of the sensor, it helps keep dust and debris off the sensor surface during long-exposure sessions, which is particularly useful when you are changing lenses in the field.
