Hubble Optics’ UL24 Dobsonian

Hubble Optics

Hubble Optics, known for manufacturing high-quality Newtonian reflector optics, now offers the UL24, a 24-inch f/3.3 ultra-light Dobsonian ($9,500). This fast Newtonian reflector is built for travel, featuring a lightweight “sandwich” mirror that drastically reduces its weight and cool-down period compared to solid mirrors. The UL24 weighs only 154 lb (70 kg) when fully assembled, and breaks down into its constituent parts to fit into most compact vehicles. The scope’s primary and secondary mirrors feature 96% enhanced-reflectivity coatings, and its eyepiece stands just 77 inches from the ground when pointed at the zenith. The telescope uses eight precision-machined trusses and an optimized primary flotation system supporting the primary mirror. The telescope includes a dual-speed, 2-inch Crayford-style focuser with linear bearings engineered to support the heaviest eyepieces available today.
