Balancing Act

March 9, 2018 - Exciting progress took place in February at subcontractor Asturfeito in Spain, where personnel assigned to the Telescope Mount Assembly (TMA) engaged in balancing and metrology activities.

Although LSST’s telescope will eventually be controlled by computers, current balancing activities require a manual approach in which the telescope, while floating on oil, is moved by winches. Measurements of the force on the telescope are taken to ensure the telescope is balanced whenever it’s off-zenith. This video, taken during the balancing of the elevation structure, illustrates the process.
