BRESSER - A parabolic primary mirror for crisp, detailed views, including a precise GoTo mount with intuitive Wi-Fi app control

The telescope set, consisting of the BRESSER Messier NT-150s/750 tube and the modern EXOS-2 PMC-Eight GoTo mount, is an impressive combination of portable, powerful optics and user-friendly mounting. Thanks to the parabolic primary mirror and the 150 mm aperture, you can capture impressive details of nebulae, galaxies, and many other fascinating celestial objects. The high-quality solar filter also allows for safe solar observation. With the reliable GoTo control and the user-friendly ExploreStars app, navigating the sky becomes effortless. Additionally, the tracking to compensate for Earth’s rotation is exceptionally precise with the PMC-Eight GoTo mount.

The Telescope

The BRESSER Messier NT-150 is distinguished by its good portability and razor-sharp optics with a parabolic primary mirror. The 150 mm aperture allows you to observe even smaller nebulae in the vastness of space. Discover the remnants of a massive star explosion from the year 1054 in the Taurus constellation or trace the glowing filaments of the Great Orion Nebula. Spot the famous Pinwheel Galaxy in the constellation Ursa Major or find the Dumbbell Nebula in the constellation Vulpecula. With the high-quality objective solar filter, you can also safely observe sunspots, eclipses, and planetary transits. (Warning: Never aim the telescope at the Sun without a solar filter!)

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, providing all necessary interfaces. The NEMA-11 stepper motors are directly connected to this unit via cable, and an ST-4 compatible autoguider interface is also available. Additionally, the control system supports micro-stepping to ensure precise tracking.

Intuitive control via app and graphical star map
The specially developed ExploreStars app for the PMC-Eight system impresses with an intuitive and visually appealing interface. The currently available alignment stars for control initialization, as well as all celestial objects in the database, are displayed as a star map with additional text information. All these objects can be easily viewed and selected.

Powerful controller unit with Open GoTo for customization
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 function. This enables remote operation via browser, ASCOM, app, or serial connection. The Open GoTo system also allows for custom firmware to be written and uploaded to the controller unit. This enables customized adjustments to the device's functions and the creation of custom object lists.

Polar finder included
The pre-installed polar finder scope included in the package allows for 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.
