# Will the James Webb telescope have any visible spectrum cameras?

The telescope itself will operate in wavelengths from 0.6 µm (orange) to 28.5 µm (mid-infrared), so it reaches a bit into the visible spectrum, but it's still going to be aimed away from Earth, and photograph distant galaxies.

What I'm interested in is, will the satellite contain any cameras that can take common visible light photos of Earth? Just like DSCOVR can take impressive images of Earth and the Moon from $L_1$, will we have similar images from James Webb at $L_2$, of the permanent corona eclipse of the Sun by Earth, or the always-crescent Moon?

• Hi SF. I really don't see how the question of whether the telescope will have any visible-spectrum cameras touches on the subject of Lagrangian points, so I removed that tag as it does not seem to help categorize the question. – user Mar 22 '16 at 10:20
• @MichaelKjörling: The telescope will be placed at L2, thus the pictures (if any) will be taken from there. It's a place with very interesting views. – SF. Mar 22 '16 at 10:22
• I don't doubt that, but still feel the question of whether the telescope itself will have visible-spectrum cameras do not require knowledge about Lagrangian points to answer. – user Mar 22 '16 at 10:25
