MelbourneAustralia1869Reflector48In PartsA reconstruction of the telescope using some of the original parts and a new glass mirror was used for the very successful MACHO project from the late 20th century onwards. Unfortunately it was destroyed in the Mt Stromlo fire of 2003. However, the heavy original parts were not much damaged and a project is now under way in Melbourne to reconstruct the instrument in its original form.
