although not a professional astronomer, beames' work making telescopes and other instruments has been praised by both amateur and professional astronomers as masterpieces of craftsmanship and engineering which have contributed to the development of the field in nsw and australia. the 24 inch reflector telescope beames completed in 1939 was the largest amateur or professionally constructed reflector telescope in nsw and retained this status until the 40 inch and 24 inch telescopes were constructed and installed at the siding spring observatory in the mid 1960s. the only other amateur built telescope to rival beames was that built by captain baker in 1868 for the ballarat observatory and the only professional telescope that was larger than beames 24 inch telescope was the 30 inch reynolds reflector telescope at mr stromlo. the beames 24 inch telescope was also unique as one of the first large telescopes in australia to incorporate electric motor drives to operate the telescope and dome.
