SOFIA telescope inside cavity
Date
Extremely rare photo of the SOFIA telescope inside the cavity with the upper rigid door closed shot using a 180-degree fisheye lens. Photographer Greg Perryman was standing with his back against the pressure bulkhead looking aft inside the cavity, and the primary mirror, the back of the secondary mirror, the tertiary mirror, and the Focal Plane Imager (small can on front of telescope in upper left of the photo) can be seen. The large brown wedge dominating the right side of the photo is the telescope cavity aperture, which helps deflect air from the slipstream out of the cavity.
