ZWO UV IR CUT Filter - 1.25"

Your images look blurry. Stars look bigger than they should. The problem is not your telescope. The problem is UV and IR light sneaking into your camera. The ZWO UV IR CUT Filter - 1.25" blocks both. You get clean, sharp, detailed images from the very first shot.

What Does This Filter Actually Do?

Your camera sensor is very sensitive. It picks up ultraviolet (UV) light and infrared (IR) light. Your eyes cannot see these wavelengths. But your camera can. UV light adds a bluish haze to your photos. IR light makes your stars look puffy and out of focus. Both wavelengths reduce the overall sharpness of your image.

The ZWO UV IR CUT Filter - 1.25" works like a traffic gate. It stops UV and IR light at the door. Only visible light gets through to your sensor. The result? Stars look tight and sharp. Colors look accurate. Details come out clean. This is not a luxury upgrade — it is a basic necessity for serious astrophotography.

Who Needs the ZWO UV IR CUT Filter - 1.25"?

This filter works great for anyone who does planetary or deep-sky imaging. If you use a refractor telescope, this filter is almost mandatory. Refractors are not always corrected for UV and IR light. Without this filter, you will always fight blurry edges and bloated stars.

It also works well for monochrome and color CMOS cameras. If you shoot the moon, planets, or star clusters with a 1.25" camera setup, this filter makes a clear difference. Beginners benefit too. You do not need to know everything about optics. Just screw this filter in and your images improve right away.

How Is This Different From the 2" Version?

The ZWO UV IR CUT Filter - 1.25" fits smaller camera setups and filter wheels. The ZWO UV IR CUT Filter - 2" fits larger imaging systems. Both do the same job — block UV and IR light.
