Abstract

Wind is a well known performance detractor for telescope pointing. Increasing the size of the telescope increase the aeroelastic effect onto the performances of the telescope. A dome is often used for larger telescopes to minimize those interactions. Rapid pointing telescope requires rapid domes, which usually are heavy drawing their cost not negligible respect to the overall amount of budget required. For this reason fast telescope's dome are usually fully deployed leaving the telescope unprotected from the wind. This paper wants to show a modification of the fully foldable tents in order to realize a partially foldable light-weighted tent able to follow the alt-az fast movement of a large scale telescope protecting it from aeroelastic loading without interacting with the dynamic of the main system. The alt-az movement of the telescope is decoupled from an azimuth rotation of the full tent and an alt motion of the two shells. In this way it is possible to work with a fully emyspherical tent and aan opened window for the observations.
