EXPLORE SCIENTIFIC HR Coma Corrector

These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil.Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus. This also maximizes the life of the internal coatings.To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes. All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

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.

With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.These teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.FEATURES: Suitable for visual observations and astrophotographyDoubling the effective total focal length of the telescopeFour lens telecentric design Fully multicoatedFilter thread for color or nebula filtersSCOPE OF DELIVERY: Fokal Extender 2 x Adapter 2" (50,8mm) auf 1,25" (31,7mm)

Are you having trouble focusing your eyepiece or camera? Then use this BRESSER 25 mm extension sleeve to increase the distance between the 2.5 inch HEXAFOC eyepiece extension and the eyepiece or camera. The extension sleeve has an M68x0.75 mm internal and external thread and can therefore be screwed directly onto the HEXAFOC draw tube.SPECIFICATIONSIncreases the distance to the eyepiece/camera Suitable for 2.5 inch HEXAFOC Optical length: 25 mm Internal and external thread: M68x0,75 mmInside black matt coated Material: aluminium, black anodized SCOPE OF DELIVERYExtension sleeve 25 mm (1 piece)
