How to Build an Infrared Telescope Camera

Infrared cameras are capable of capturing a broader spectrum of light than can be seen with the naked eye. Infrared radiation, though invisible to human eyes, can appear in images made by cameras modified to be sensitive to the infrared spectrum. Normal digital cameras shield their sensor with an infrared filter. By removing this filter and attaching your camera to a telescope, you can take photographs of distant objects that cannot normally be seen.

Instructions

    • 1

      Take apart your camera to access the digital sensor. On less expensive point-and-shoot cameras, the body may be held together with glue. More expensive dSLR (digital Single Lens Reflect) cameras are likely held together with screws. Your camera's user's manual will provide you with the steps necessary to disassemble your camera. Look for a section similar to "cleaning your digital sensor."

    • 2

      Locate the infrared filter. It will look like a small, square piece of glass or plastic that is fitted over the front of the digital sensor.

    • 3

      Remove the infrared filter. Some filters are held on with screws, but many are affixed with a weak glue and can be pried off with your fingernails.

    • 4

      Reassemble your camera.

    • 5

      Attach your T ring to the front of your camera body where a lens would normally go. These rings should be purchased from your camera manufacturer so that you are sure that the ring will fit your body.

    • 6

      Screw in your T adapter to your telescope's eyepiece.

    • 7

      Attach your camera with the T ring to the T adapter as if you were attaching a long telephoto lens. The assembly should lock together tightly with no wobbling between the camera and telescope.
