  In the context of ADONI - the ADaptive Optics National laboratory of INAF -
we are arranging for a facility, accessible to the AO community, in which
visiting multi-purpose instrumentation, e.g. systems and prototypes of
innovative AO concepts, may be directly tested on sky. The facility is located
at the 182cm Copernico telescope in Asiago, the largest telescope in Italy, at
its Coude focus, for which refurbishment activities are carried out, given that
this focus was initially foreseen in the design, but never implemented and used
till today. The facility hosts a laboratory where specialized visiting AO
instrumentation may be properly accommodated on an optical bench for on-sky
demonstrations. We present the current status of the facility, describing the
opto-mechanical design implemented at the telescope that allows to redirect the
light toward the Coude focus, the tests on the opto-mechanics carried on for
stability verification, the integration of the optical and mechanical
components within the preexisting structure.
