With the BRESSER Messier AR102s/600 telescope and the EXOS-2 PMC-Eight GoTo mount, you are well-equipped to explore both the Sun and the night sky. Ambitious beginners and advanced users can use the optics with a 102 mm aperture and a focal length of 600 mm to discover the brightest objects beyond our solar system. Enjoy impressive views of fascinating star clusters. You can also safely observe the Sun with the help of the solar filter. The modern mount, equipped with GoTo control and the intuitive ExploreStars app, ensures precise tracking and easy navigation of the sky.

The Telescope

The BRESSER Messier AR102s is a high-quality telescope for night and solar observation. Ambitious beginners and advanced users will already find the brightest objects outside the solar system with this device. Discover structures in the Orion Nebula at an incredible distance of 1,500 light-years (14,200,000,000,000 km)! Exploring the light-dark boundary (terminator) on the Moon is a delight. And with the high-quality objective solar filter, you can safely observe sunspots, eclipses, and planetary transits. (Warning: Never aim the telescope at the Sun without a solar filter.) You will never want to part with the Messier AR-102S.

The Mount

The EXPLORE SCIENTIFIC EXOS-2 PMC-Eight GoTo mount is equipped with a modern and highly precise GoTo control system. It consists of a robust Wi-Fi controller unit that provides all necessary interfaces. The NEMA-11 stepper motors are directly connected to this unit via cable, and a ST-4-compatible autoguider interface is also available. Additionally, the control system supports microstep operation to ensure precise tracking.

Intuitive operation via app and graphical star chart
The ExploreStars app, specially developed for the PMC-Eight system, impresses with its graphically successful, intuitive user interface. The currently available alignment stars for system initialisation, as well as all celestial objects in the database, are displayed as a star chart with additional text information. All these objects can be easily viewed and selected.

Powerful controller unit with Open GoTo for customisation
The heart of the controller unit consists of a fully autonomous 2-channel multi-processor with 8 CPUs and a Wi-Fi Ethernet 10/100 adapter with IP functionality. This enables remote control via browser, ASCOM, app, or serial connection. With Open GoTo, you can also write your own firmware and load it into the controller unit, allowing for custom adjustments to the device functions and the creation of your own object lists.

Polar finder included
The pre-installed and included polar finder scope enables quick and precise polar alignment and long exposure times without unwanted star trails. The integrated LED lighting unit further enhances the usability of the polar finder.
