Optical-infrared astronomy in Europe is in a state of transition and opportunity, with the goal of a viable structured European scale community in sight. A strong astronomical community requires access to state of the art infrastructures (telescopes), equipped with the best possible instrumentation, and with that access being open to all on a basis of competitive excellence. Further, the community needs training in optimal use of those facilities to be available to all, Critically, it needs a viable operational model, with long-term support from the national agencies, to operate those infrastructures. The most important need for most astronomers is to have open access to a viable set of medium aperture telescopes, with excellent facilities, complemented by superb instrumentation on the extant large telescopes, while working towards next generation instrumentation on the future flagship, the European Extremely Large Telescope. OPTICON has made a substantial contribution to preparing the realisation of that ambition. OPTICON supported R&D has, and is developing critical next-generation technology, to enhance future instrumentation on all telescopes. The big immediate challenge is to retain a viable set of well-equipped medium aperture telescopes. The present project is to make the proof of principle that such a situation is possible - a situation developed by OPTICON under its previous contracts, in collaboration with the EC supported strategy network ASTRONET - and set the stage for the step to full implementation.
