DIGITAL CATALOG Astro Devices introduces the Nexus DSC ($449.95), a digital setting circle computer for your telescope. The Nexus DSC unit features a database of more than 60,000 objects and can be expanded to up to 1.7 million objects via an optional Micro SD memory card. The unit displays information on a red OLED display that functions at very low temperatures, powered by an internal rechargeable lithium battery. Nexus DSC automatically detects and inputs the precise time and location with its built-in GPS receiver. The DSC can connect with most tablets, smartphones, and computers through an RS232 cable or via an optional Wi-Fi interface. The unit is compatible with ServoCAT and SiTech motor controllers and most planetarium software programs. Telescope encoders are sold separately. See the manufacturer's website for additional details.
