Abstract
The article discusses the creation of the Newton ad Alto Contrasto Telescope (NAC), a high-contrast Newtonian telescope designed to provide refractor-like images at a lower cost. The telescope was built by Italian ATM Roy Cerreta, who wanted to replicate the performance of professional refractors he had observed with. The NAC features a 254-mm f/12 system with a precision mirror and a three-part OTA made of marine plywood. Initially yoke-mounted, the telescope was later converted to an altazimuth mount for increased portability. Despite some damage, the NAC continues to be a work in progress, with plans for a lighter Dobsonian-style rebuild. [Extracted from the article]
