Vixen VMC200L Maksutov-Cassegrain mirror telescope - optical tube (Refurbished)

The optics of the VMC260L surpass the traditional Schmidt-Cassegrain and this tube is only 650 mm in length, despite its long focal length of 3000 mm . With its large aperture of 260 mm , the telescope collects light for serious professional observations and photography of the planets, as well as countless deep-sky objects. The dielectrically coated mirrors of the VMV260L guarantee high sharpness and maximum brightness. Thanks to the open tube, this instrument cools down faster than conventional closed Cassegrain systems, and (having no front corrector plate) is not as prone to dewing issues either.An optional 0.62x focal reducer is available for expansion to reduce the focal ratio to 1: 7.1. This results in a shortening of the exposure times and the increasing the field of view, thus increasing the ability to photograph larger objects in the sky. Included accessories feature a finder, dovetail rail and a handle that assists considerably when mounting and de-mounting the scope and can also be used as a camera holder for star field recordings.CHARACTERISTICSAperture: 260 mm precision spherical mirror, multi-coatedLight gathering power: 1380xAdapter and connections: 60 mm on the focuser; 42 mm for T-mount and 31.7 mm with folding mirror; 50.8mm optionPhotography: primary focus and eyepiece projectionWHAT'S INCLUDEDVMC260L reflectorDovetail rail (3 inch for AXD)AXD SaddleplateCarrying handleFinderscope 7x50Flip mirror

One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC UHC filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The Explore Scientific UHC nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the Owl-nebula M97, the Veil-nebula NGC6992 or even the bright Dumbell-nebula M27 are not clearly visible. By using this filter you can see the nebulae and their structures without problems. A must for every visual observer. The EXPLORE SCIENTIFIC nebula filters come with a individual test certificate - your guarantee to receive a premium filter.FEATURESenables the observation of emission nebulaeblocks almost the entire artificial lightonly the two emission lines of hydrogen and oxygen passes the filterWHAT'S INCLUDED1x 1.25" UHC nebula filter
