JMI NTT 30 inch Folding Newtonian

For sale is a JMI NTT 30 inch folded Newtonian. This is a rare opportunity to purchase a really large quality scope. This would suit keen amateurs or astro societies. The folded Newtonian provides a convenient viewing position compared to a regular Newt design requiring large ladders or steps to reach the eyepiece. The mount is an Alt-Az design as shown in the images with a GoTo system. The scope has been unused for a number of years and the primary mirror would be best recoated for ideal performance. For more details see: http://www.jimsmobile.com/buy_ntt30.htm
Various Teleview eyepieces are also included. The scope is located in Sydney NSW. Buyer to arrange pickup. There is also a 6 metre motorised Sirius dome currently housing the instrument which would require disassembly and transport.
