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.

In order to keep the adjustment distances by using the knurled screws as small as possible, the mounting plate has a quick-release clamping device with toothing in order to be able to select a rough presetting of the pole height (latitude at the location). The Micro Motion Head MH-100 can be mounted on any photo tripod with 1/4 inch photo thread closure. The BRESSER StarTracker astrophoto mount can then be mounted on the MH-100 tripod head without the use of tools using a 1/4" photo thread screw. The complete motion head is made of black anodized aluminum and guarantees highest stability by the use of solid material. The knurled screws with fine pitch thread are even made of stainless steel and guarantee a long durability and corrosion resistance.Ideal for optimizing tracking accuracy in astrophotography.IMPORTANT NOTE:Can also be used as a stable adjustment element of a telescopic sight in astrophotography. Parallel alignment of the main telescope and the guide telescope is thus also possible quickly and precisely. Base plate connection: 3 x 1/4 inch photo thread with 35.0 mm hole spacing. Mounting plate connection: 2 x M8x1.25 thread with 35.0mm hole spacing.FEATURESCompact micro motion head with fine adjustmentFunctions as a so-called polar-wedgeFor precise adjustment of polar alignment (EQ mode)Mounting plate with quick-release clamping device and toothingCan be used with any photo tripod and 1/4inch thread adapterMade of black anodised aluminium and stainless steelQuick and easy to use deviceSuitable for BRESSER StarTracker Astrophoto Mount PM-100Suitable for BRESSER tripod TP-100 DXAlso ideal as an adjustment element of an auto-guiding scopeFor parallel alignment of main telescope and guiding telescopeBase plate connection: 3 x 1/4 inch photo thread; hole spacing 35.0mmConnection mounting plate: 2 x M8x1.25mm thread; drilling distance 35,0mmSCOPE OF DELIVERYMicro Motion Head MH-100Instruction manual
