Why do they call it an infrared telescope when it doesn't see in the infrared spectrum?
- Sharlin 4y agoIt does in near IR, but yeah, it’s as much a visible light telescope as an IR one.
- Someone 4y agoIt sees the near infrared. I expect they got that for free from the camera sensor. https://en.wikipedia.org/wiki/Infrared_photography#Digital_cameras https://en.wikipedia.org/wiki/Infrared_photography#Digital_c...: “Digital camera sensors are inherently sensitive to infrared light, which would interfere with the normal photography by confusing the autofocus calculations or softening the image (because infrared light is focused differently from visible light), or oversaturating the red channel. Also, some clothing is transparent in the infrared, leading to unintended (at least to the manufacturer) uses of video cameras”
