This complete telescope and mount bundle is built for aspiring astronomers and intermediate observers looking to dive into both planetary detail and deep-sky exploration. The combination of classic optical performance and advanced GOTO tracking makes this a perfect all-in-one solution.
At the core is the FirstLight AR80mm f/8 achromatic refractor, known for its crisp, contrast-rich views of the Moon, Saturn’s rings, Jupiter’s belts, and bright nebulae and clusters. With fully coated optics, a 640mm focal length, and a 1.25" diagonal, this telescope delivers dependable clarity night after night.
Paired with the iEXOS-100 PMC-Eight™ Equatorial Tracker, this setup unlocks GOTO object tracking and remote control capability through the ExploreStars app or any ASCOM-compatible software. Whether you're observing visually or imaging through a camera, the 8-core microcontroller system ensures smooth, accurate motion and exceptional performance.
