BRESSER - For wide-field observation and astrophotography, incl. a precise GoTo mount with intuitive Wi-Fi

A compelling combination: Enjoy spectacular sky observations with the BRESSER Messier AR-127S/635 tube and the EXOS-2 PMC-Eight GoTo mount, both day and night. Thanks to its compact design, the telescope is perfect for wide-field observations, such as breathtaking views of the Andromeda Galaxy or large gas nebulae. The four-lens achromat with its large 127 mm aperture provides high contrast and minimal color aberration. The high-quality solar filter also allows safe observations of our home star. This modern mount provides precise tracking and intuitive sky navigation via the app for all your astrophotography and exploration needs.

The Telescope

As a quality telescope for night and solar observations, the BRESSER Messier AR-127S/635 tube with its compact design offers particularly large and bright fields of view. Be sure to use it to observe the Andromeda Galaxy! The light from this object, visible over 2 million light-years away, is as spectacular through this telescope as observing large gas nebulae. Thanks to the large aperture, the Messier AR-127S/635 can use nebula filters that enhance gas nebulae with remarkable contrast. The special construction as a four-lens achromat achieves minimal color error and better photographic correction than comparable two-lens devices, even with a very fast focal ratio of f/5 for a refractor. With the high-quality solar filter, you can safely observe sunspots, eclipses, and planetary transits. (Warning: Never point 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, highly accurate GoTo control system. It consists of a robust Wi-Fi controller unit providing all necessary interfaces. The NEMA-11 stepper motors are connected directly to this unit by cable, and an ST-4 compatible autoguider interface is also available. Additionally, the control supports micro-step mode for precise tracking.

Intuitive operation via app and graphic star map
The ExploreStars app, developed specifically for the PMC-Eight system, offers an intuitive, visually pleasing user interface. The app displays available alignment stars for system initialization and all celestial objects in the database as a star map with additional text information. All objects can be easily viewed and selected.

Powerful controller unit with Open GoTo for customization
The heart of the controller unit is a fully autonomous, 2-channel multi-processor with 8 CPUs and a Wi-Fi Ethernet 10/100 adapter with IP functionality. This setup enables remote operation via browser, ASCOM, app, or serial connection. Open GoTo allows custom firmware to be written and loaded onto the controller, enabling individual customization of device functions and the creation of custom object lists.

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