The telescope configured for measurements of exoplanet transit light curves is seen from the north side in this May 2010 photo. Lower portions of the dome have been insulated to reduce daytime heating by radiation from the warm metal dome. ... The interior of the dome is seen soon after the encoder upgrade in February 2007. ... Karen Collins, a research astronomer specializing in exoplanets, helped with the telescope installation in August 2006. ... kielkopf at louisville dot edu . ...

The pupil mirror array for NIFS was successfully manufactured in early October 2001 by Labor fuer Mikrozerspanung (LFM) of the University of Bremen. The monolithic array of 29 toroidal mirrors are diamond machined in an aluminum bar. ... White light interferometric image of the central element of the pupil mirror array. Pupil mirror array.

A display unit that connects directly to the output of the Australia Telescope Distributed Clock (ATDC) is now at the end of the prototyping stage and is ready for production. Initially fifteen units will be produced to replace the current ATDC terminal screens at Parkes, Narrabri, Mopra and Epping. ... This was overcome by using a fine transparent conductive mesh over the display area to attenuate the interference. A prototype display unit for the Australia Telescope Distributed Clock. ...

... I used Ґ inch thick Appleply plywood throughout. ... The mirror box is a little unusual. ... The original design uses a fiberglass tube to connect the mirror base plate to the top ring to form the mirror box. ... I decided to build the mirror box like a standard secondary cage instead, using aluminum tubes with push-in inserts. ... All three tubes are retained at the mirror box and the secondary ring using nine, 1-inch thick Appleply clamps, three at the secondary and six on the mirror box. ...

... This sp ectral distribution is defined b oth by the energy distribution in the target star's sp ectrum and by the sp ectral resp onse of the detector, i.e. by the central wavelength 0 and the effective sp ectral bandwidth . ... On the right: The collection of the MASS sp ectral resp onse curves. ... Table 1: Integral characteristics of the resp onse curves of the MASS devices. 0 -- central wavelength, ef f -- effective wavelength for A0 V stars, -- effective bandwidth (integral under the curve). ...

... Up: Adaptive and Active Optics . ... Six laser rangefinders are used to trilaterate to these prisms so that departures from paraboloidal shape due to wind pressure and thermal gradients in the backup structure can be measured. ... NRAO decided to build a 100-meter unblocked (off-axis) millimeter-wave active surface antenna, with laser rangefinders to control both mirror shape and pointing, and to call it the ``Green Bank Telescope'' [GBT]. ... Figure 1 shows the GBT as it looked in the Fall of 1999....
