. Installing Mirror in Crate: August 7, 2002 . The crate is opened and foam installed for the mirror. Weather was very overcast. See the new all-sky camera in the foreground. More photos of that when the weather improves. Do you think there is enough stuff in the bottom of the enclosure! .

... The pyramid divides the OTA image of the sky into four parts. After leaving the pyramid, each quarter of the full field of view is relayed by an optical flat to a Cassegrain relay that forms a second field image on a charge-coupled device (CCD) of 800 x 800 pixels. ... This task, in its default mode, will combine the four chips in a large, 1600 x 1600 pixel image at the resolution of the Wide Field cameras, resampling the pixels in order to correct for the chip overlap, rotations, and distortions. ...

We have designed the laboratory model of static Fourier spectrometer for onboard usage for spectral study of atmosphere and ionosphere. The gain of model is to simulate onboard FS which will not have any moving elements (all its optical elements will be mounted at fused quartz monolithic construction), to compare experimental results with theoretical estimations and to measure MTF of CCD array. ... This fact connected with low frequency response of CCD array due to small format of it. ...

. Will Saunders of the Anglo-Australian Observatory imagines a relatively simple 16m telescope at Dome C. A nearly flat, steerable reflector (right) receives light from the sky and directs it onto the primary mirror (left). The primary mirror focuses light onto a prime-focus unit halfway between the two mirrors. This unit could be a camera, a device that holds optical fibers for capturing the light, or a secondary mirror reflecting light through the primary's central hole. Andrew McGrath, AAO
