Product Description

ZWO 1.25″ IR UV CUT filter is suitable for color camera with AR protect window.

The ZWO IR-Cut Filter blocks infrared light from reaching the sensor of your CCD or CMOS camera or your expensive H-alpha filter. When imaging, the addition of this simple and inexpensive accessory will result in sharper images, and when doing solar work, the IR Cut Filter will your protect H-alpha filter from the damaging effects of infrared radiation.

Infrared or IR light is invisible to the human eye, and so even though most telescopes are not designed to focus IR light, it does not matter when you are using your telescope visually. However, when you add a camera to the mix, its a whole other story! Unlike the human eye, a silicon sensor is very sensitive to light in the infrared portion of the spectrum, and that is a problem because infrared images are blurry as all get out. That means your nice, sharp visual light image is degraded by the addition of the infrared layer. This problem can easily be solved by blocking the infrared, and the ZWO IR Cut-Off, will do just that.

The ZWO IR-Cut filter is housed in a 1.25” cell, and has internal threads so that you can stack filters together. The filter comes with a protective plastic case.

  1. :

    those the ZWO120 mono needs this filter for solar imaging?

  2. (verified owner):

    Is this a recommended filter for the ASI224MC?

    • Sam Wen

      :

      yes, you need a IR-CUT filter for 224
      you can use this one

  3. :

    Hi, Do I need this filter for the ZWO290MM? I’m trying to image the moon but I just get a white blob with no definition.
    I’ve played around with exposure, gain and gamma but still get a white blob. Thanks Ian.

    • Sam Wen

      :

      you need to adjust focus, this filter is not required for moon

  4. :

    I am bit confused on the filers required for the 224MC-so you would use this cut out fliter so that you can see color in planetary imaging such as Jupiter?

    • Sam Wen

      :

      the cut out filter can give you the real color of the planets

  5. :

    Just recently bought an ASI290MC, doesn’t this camera have an IR Cut filter built in to the protect window?

    • Sam Wen

      :

      it use AR protect window

  6. :

    Hi Sam, what’s the thickness of the filter glass?

    • Sam Wen

  7. :

    Which filter is preferable for solar imaging with ASI224MC, this one (UV IR CUT filter) or the IR 850nm Pass Filter? Is different filter preferable for planetary imaging? Thanks

    • Sean Wang

      :

      UV IR-CUT is suitable for solar imaging.
