In1852 the Reverend Mr.John Craig established with the help of various engineers including William Gravatt, what was at the time the world’s largest refracting telescope on Wandsworth Common in London. The main aperture of the telescope was 24 inches and had a focal length of 76 feet; a wonder of science and engineering for the time.
The build comes in two parts, the ‘Craig telescope’ and the ‘Telescope chain assembly’. To begin simply upload each build to your sim. Firstly modify the linking of the ‘Craig telescope’ so that the tower is the root prim, next modify the linking of the ‘Telescope chain assembly’ so that the tower cap is the root prim. Finally set the x,y coordinates of both builds so that they are the same, rotate as necessary and raise the ‘Telescope chain assembly’ so that the cap sits on top of the tower.
