Each image was taken through a different colour filter. From left to right, the images show how Betelgeuse appears in red (a wavelength of 700 nanometres), very near-infrared (905 nm), and near-infrared (1290 nm) light. To show this, we have coloured the images different shades of orange and red. 700 nm . ...

The Canadian scientific satellite Isis-2 (1971) carried an auroral imaging camera and discovered the diffuse aurora, a broad ribbon around the auroral oval, too spread-out to be noticed from the ground. ... Currently, NASA's Polar (1996) collects images of the polar aurora using three cameras--in visible light (sometimes as frequently as 12 seconds apart), in ultra-violet and in x-rays. ...

... The wind baffle fits closely about the telescope. It is supported by the building and protects the telescope from the wind and stray light. With the wind baffle removed, the secondary truss and interior light baffles are visible. The interior light baffles consist of the secondary, conical and primary baffles (top to bottom). ... The conical baffle (center) blocks stray light paths that would otherwise have to be intercepted by the primary and secondary baffles. ...
