BRESSER Extension tube 2"/35mm

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.

Adapter 2" with brass locking ring for 1,25" eyepieces. The integrated T2 thread adapts DSLR or astro-cameras (*appropriate T2 ring for your camera model needed). On the telescope side there is a 2" filter thread M48x0.75, which allows the easy use of colour and nebula filters.SCOPE OF DELIVERYCamera Adapter 

The BRESSER UV + IR Cut Filter makes lunar and planetary images even sharper.Digital astro cameras have a wide sensitivity range that significantly exceeds the spectrum of visible light. Thus, the wavelengths of invisible light in the ultraviolet and infrared are also captured. This leads inevitably to a small additional and of course unwanted blur. The solution is this UV + IR Cut Filter, which allows only light in the visible range 400 nm to 680 nm to pass through and blocks all other wavelengths of light. As soon as these disturbing light waves are cut off, the sharpness of the image and the contrast are increased. Suddenly, details on the surface of Jupiter, for example, can be seen that were previously only barely visible. A clear plus, which can be achieved by this filter.Suitable for BRESSER CMOS cameras and other manufacturers with female camera thread M30 x 0.75 mmAfter removing the original screw adapter with sensor protection glass, the BRESSER UV + IR Cut filter is mounted to the camera instead. This filter has a fine M30 x 0.75 mm external thread for mounting on the camera. The exchange is therefore quick and easy. On the opposite side, i.e. on the telescope side, there is a standard C-mount female thread for mounting other accessories. Note: This filter does not have a standard 1.25 inch (31.7 mm) filter thread.
