provided a large support to provide stability. The Royal
Society Committee would go on to describe the telescope as 'a masterpiece of engineering'. This project would become renown amongst the global astronomers community and bolster Grubb's reputation. Unfortunately, the project would end in failure when the telescope was actually dismantled and shipped to Australia. Grubb was tasked of constructing a Cassegrain reflector that would include two 4-foot metal mirrors. The problem with the project was Grubb's choice of metal. This caused defects in the form of the astronomers in Melbourne being unable to re-polish the mirrors adequately.

Thomas Grubb would begin his professional career in Dublin, Ireland in the year 1830 as a mechanical engineer.
