What is the focal length of the Jeffree telescope in the Astrograph House at Melbourne Observatory? The info on your site http://museumvictoria.com.au/collections/items/730608/negative-jeffree-telescope-melbourne-observatory-circa-1960 only says it's a reflecting telescope with an aperture of 310mm. --gd

Hi Geoff, the telescope has a 12.5-inch aperture and is about f/8, so its focal length is about 100 inches or just over 2 m. We've updated our records to reflect this information, which should appear online in the next couple of weeks. Thanks so much for your question!
