Vixen Polarie Star Tracker Camera Mount for Astrophotography (Refurbished)

NEW - now including a high-quality lens solar filter for the safe observation of sunspots, eclipses and planetary transits. A high quality telescope for night and solar observation.The BRESSER Messier 10 "Dobsonian is something very special. Despite the low price, it offers a variety of functions and quality that are sometimes unavailable in considerably more expensive telescopes. With its 254 mm diameter optics, this telescope is not limited to solar system observation of the Moon and brighter planets - you can also observe far out into the universe and see globular clusters, nebulae and galaxies. Details become visible in most deep-sky objects: globular clusters are broken down into individual stars and nebulae, which are only hinted at in smaller scopes, show considerable structure. This Dobsonian is unsurpassed in versatility within its price range: the excellent, large Hexafoc focuser has an opening of 65 mm - so even with large wide-field eyepieces, there is no noticeable vignetting from the eyepiece extension tube. The large elevation wheels also hold the telescope level with just the right amount of "sticktion", even when heavier eyepieces are used. And when a lot of heavier accessories are attached, such as the Bresser Binoviewer attachment, then the entire telescope tube can be moved within the tube rings - and everything is balanced again in a flash. The unsurpassed rigidity of the focuser makes it easy to focus - photography with this OTA is no problem either as the supplied extension tube for the focuser can be removed and a camera easily bought to a prime focus position. This is another strength of this universal telescope: if you want to take photos, you can simply unscrew the elevation wheels from the tube and place it on an equatorial mount with a standard dovetail rail - other rival Dobsonians do not offer this level of flexibility or pathway to more expansive astrophotography use. An optional dual speed 10:1 gear reduction for the focuser is available for those who need extra fine control of focus. If you consider that the focuser is the telescope part that is used most often, the supply of the Hexafoc on this telescope is a quantum leap for this price range.With the initial equipment you can observe immediately - a 6x30 viewfinder and a 25mm SPL eyepiece are included within the package.  If you want to transport the device as compactly as possible, it is easy with the new 10 "BRESSER Messier - the rocker box can be dismantled in a few simple steps, as the parts are assembled with metal quick-release connectors. A bulky rocker box quickly becomes a handy flat package of boards within a few minutes. This is a telescope whose versatility, performance and ease of use set new standards in this price range.Please note that while Newtonian type reflecting telescopes are very good for astronomical observations in the night sky, they not well-suited for observing nature and landscapes during the day. We therefore recommend BRESSER refracting or Cassegrain designs of telescopes for additional nature and landscape observations.PROPERTIESType: mirror telescopeMirror diameter: 254mm / focal length: 1270mm / F / 5Maximum useful magnification: 508 timesTelescope for night and solar observation2.5" HEXAFOC focuserMain mirror made of special glass, with low thermal expansionHassle-free focusing, even with heavy accessoriesEasy to move tubeDismountable rocker boxTube mounting on altitude bikes using clampsUse of the optics on other mounts as wellAdjustment and construction screws of different sizesBase diameter 54cmWhat's IncludedTube with Newtonian opticsFull aperture Solar filter6x30 viewfinder25mm Super Plössl eyepiece (Ø 31.7 mm / 1.25 ")1 extension tube 37.5mm for 2.5 " Hexafoc1 eyepiece adapter 1.25" to 2"/31.7 to 50.8 mm2 Tube Rings2 Altitude support wheelsRocker box with 2 base plates and mounting material (disassembled for self-assembly)Shipping dimensions Box1: 134x44x44cm - 19.0kgShipping dimensions Box2: 61x61x24cm - 17.0kg

The Vixen POLARIE is a new camera accessory, that enables you to capture sharp, point-like images of the stars. It has been developed to track the stars and to compensate for the movement of the earth. POLARIE enables you to take atmospheric shots of landscapes and the night sky and can also capture these in sharp images. Extremely simple and compact design for use in every location on earth. If you have ever viewed a romantic, starry sky, you will surely have felt the desire to capture it on film. But if you have tried to do this, you will know that it’s really not all that easy. This is because you need to have multiple exposures of several minutes if you want to photograph the stars. As our earth is always turning on its axis, the stars keep moving as time passes and become long strokes on photographs. Today’s digital technology gives us the option of obtaining shorter exposure times by increasing the sensitivity of the sensor, but, unfortunately, this dramatically increases picture noise and the picture becomes very noisy and ugly. This makes it impossible to take beautiful images of the night sky. For this reason, the Vixen company has developed the Polarie Star Tracker, which eliminates the problem of star migration. When you attach your camera to the Polarie, the device will track in the opposite direction of earth’s rotation and this allows for sharp, point-like images of the starry sky even when using long exposure times. POLARIE is a new and unique camera accessory for photographing the night sky, with perfectly point-like stars being tracked. Using the simplest solution, it makes the experience of photographing the night sky more accessible for everyone. The multi-functional mode dial is adjustable for sky- and landscape-, moon-, sun- and star-tracking. Polar altimeter for a fast focus. Also included: USB connection for external power supply and a built-in compass for quick orientation. Available as optional extra accessories are a polar finder telescope for exact alignment with the celestial pole for long-exposure photography including into the telephoto range, and a tripod.
