Problem
The New Technology Telescope (NTT) is operated by the European Southern Observatory at Cerro La Silla. This telescope was used as a testbed for evaluating the adaptive optics technology used in the VLT. The NTT has a 3.58-m primary mirror with a focal ratio of f/2.2.
(a) Calculate the focal length of the primary mirror of the New Technology Telescope.
(b) What is the value of the plate scale of the NTT?
(c) ϵ Bootes is a double star system whose components are separated by 2.9′′. Calculate the linear separation of the images on the primary mirror focal plane of the NTT.
