The GSFC acousto-optic tunable filter (AOTF) camera was used at the Apache Point Observatory 3.5 meter telescope in Sunspot, NM, to image the night side of Venus. In the near-infrared, there are several spectral regions that are relatively clear in the Venus atmosphere. ... By imaging the Venus night side, an AOTF camera can determine spatial variations of trace molecular species in the Venusian atmosphere, and even study the dynamics of the zonal winds on Venus. ...

The atmospheres of the major planets, three of the four planetary ring systems, and numerous asteroids have been probed with stellar occultations. ... With stellar occultation data we can also probe for close companions and possible tenuous atmospheres. ... Copyright (c) Amateur Telescope Makers of Boston, Inc. ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...
