BRESSER Single Polarizing Filter 1.25"

This Herschel wedge is designed for superior White-Light solar observing and imaging. It can be used with refracting telescopes up to 102mm aperture, with 1.25'' focuser. This complete system comes with installed ND3.0 filter.Herschel Wedges are used to observe the sun in White Light. Around 95% of the Sun's light is suppressed by the wedge's ceramic prism. The remaining sun light is dimmed further by a factory-installed ND3.0 grey filter. Lunt Solar Systems Herschel wedges are installed in a fully closed housing with integrated heat trap. No stray light can escape from this, therefore it is very safe method of observing our nearest star.The difference between Herschel-wedges and normal front mounted filters is that the filtering takes place just before the eyepiece or camera. This provides better contrast and sharpness of the solar image - with more surface detail visible as a result.  Furthermore, a Herschel wedge is inherently safer than at a front mounted filter. A Herschel wedge can not rip or become punctured like a foil filter can be and it cannot become detached from the telescope objective accidentally.Only for use with refractor telescopes up to 102mm aperture:Because the full energy and heat of the sun inside the telescope, we advise solely using refractors for Herschel-wedge use. The refractor must not have corrector lenses at the back. Optical elements like corrector lenses, or secondary mirrors of reflecting telescopes, could suffer from thermal build-up by concentrated solar energy and could be permanently damaged.Tuning the brightness:Because the Herschel-wedge produces polarised light, you can use a normal polarising filter at the eyepiece, or camera-adapter. By turning the polarising filter the image brightness can be varied to the user's liking.This additional Polarising filter is not included.

An excellent set for exciting planetary and deep-sky observations: the high-quality BRESSER Messier NT-203/1200 Telescope with the modern EXOS-2 PMC-Eight GoTo Mount. The optics impress with the long focal length and very low obstruction, providing an impressively sharp and high-contrast image. This reveals numerous exciting details on Jupiter and Mars. More distant objects like emission nebulae and galaxies also show their structures. The GoTo mount, with its user-friendly ExploreStars App, quickly locates celestial objects and tracks them precisely. During the day, the Sun’s view with the included solar filter is equally fascinating. The Telescope The BRESSER Messier NT-203/1200 Telescope enables observations that were impossible at this price range a few years ago. Thanks to its longer focal length and minimal obstruction, it provides better sharpness and higher contrast for planetary observation. Modern manufacturing technology allows you to track the shadow of Jupiter's moons on the planet itself; the abundance of structures and details on the surface of Jupiter is breathtaking. This reflector telescope excels not only in planetary observation: Discover structures in distant galaxies and be fascinated by the filaments of emission nebulae in the vastness of the Milky Way. With the Messier NT-203/1200, observe the remnants of exploded giant stars and witness the birthplaces of new stars. With the included solar filter, you can explore the Sun during the day and safely observe sunspots, eclipses, or planetary transits. (Warning: Never point the telescope at the Sun without the solar filter!) Be amazed by the wonders of the universe with this exceptionally large device! The Mount The EXPLORE SCIENTIFIC EXOS-2 PMC-Eight GoTo Mount features a modern and highly precise GoTo control system. It consists of a robust Wi-Fi controller unit that provides all the necessary interfaces. The NEMA-11 stepper motors are directly connected to this unit via cable, and there is also a ST-4 compatible autoguider port. Additionally, the control system supports micro-step operation to ensure precise tracking. Intuitive operation via app and graphical star map The ExploreStars app, developed specifically for the PMC-Eight system, impresses with its well-designed and intuitive graphical interface. The current alignment stars for control initialization and all the 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 At 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 allows remote operation via browser, ASCOM, app, or serial connection. With Open GoTo, custom firmware can also be written and uploaded to the controller unit, enabling individual customization of device functions and the creation of your own object lists, etc. Polar finder included The pre-installed polar finder scope enables quick and precise polar alignment, allowing for long exposure times without unwanted star trails. The integrated LED lighting unit further enhances the comfort of using the polar finder.

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
