Freedom from Ghost images even when stacked.  Striae free substrates are polished parallel to 30 seconds of to avoid wedge errors.  Finest 7 layer  hard multicoatings on both faces feature 0.25% residual reflections (Baader filters are unique no other colored filter incorporates anti reflection multicoatings).  The coatings are also different for each of the filters in order to match the coating performance to the filter curve of each color.  This maximizes the transmission and minimizes reflections.     Extremely High Transmissions result in maximum contrast and isolation of planetary details even with smaller telescopes.  Efficiencies of the three longpass filters (Red Orange and Yellow) peaks at 98% and efficiencies of the three bandpass filters (Green Blue Dark Blue) achieve 70%.      Carefully designed spectral characteristics.  Filters may be stacked without image degradation or ghosting in order to provide even narrower passbands.  Or combine with any of the other Baader filters for interesting possibilities.     No reduction in sharpness even at high magnifications or when using the filter far ahead of the focal plane (ie digital imaging or in front of a diagonal or binoviewer). Get started with astrophotography on your Meade LX200 or LX90 telescope.  The LX200 and LX90 telescopes f/10 focal ratio makes them difficult to take long exposure photos with your DSLR Nikon or DSLR Canon EOS camera   that's why we included the Meade f/6.3 focal reducer to make the telescope Freedom from Ghost images even when stacked.

Starbeam   SCT Base with Flip MirrorStarbeam's unique flip mirror feature provides comfort and flexibility for viewing at any angle from straight through to 90. Viewed straight through you see the natural sky with a 10 arc minute (1/3 Moon diameter) The CGE Pro 925 Schmidt Cassegrain Telescope is part of Celestron's Introducing our SmartStar A R80 Entry Level refracting telescope system. Designed with the latest technology the 80 mm lens is crafted with a fluorite based low dispersion glass that is ground and polished to exact specifications.   The precision design is excellent for viewing bright stars planets and their moons as well as for bird watching and other land objects. Two eye pieces come standard to allow for flexibility in viewing either a wider field or a single focused object.Dual Mount: Alt Azimuth & German Equatorial  The CubeThe SmartStar A R80 refractor telescope comes with our patented Dual Mount: Alt Azimuth & German Equatorial a.k.a. The Cube. This compact mount design is probably the most functional and flexible unit on the market. Both axis motors are built into a small single unit which is universally compatible with all telescopes using a dove tail connection. The mount can be level for Alt Azimuth or locked into position for German Equatorial. In addition there are no dead spots  so you can point your telescope to ANYWHERE above the horizon whereas other mounts block the telescope tube at certain points of rotation. This mount also comes standard with AC connection. An optional DC adaptor is available so you can plug your telescope motor into your car if youre camping or at any remote location.The most easy to understand controller on the marketThe GoToNovaTM Controller is much easier to use than other similar products. The hand controller is more intuitive with menu categories better organized. It also has the largest LCD screen on the market with 8 lines of content compared with others that only have 2 lines. Using the easy to use hand controller you can easily set up your telescope and select where you want to go.More precise speed control for viewing objectsThe control system also allows you to slew the telescope at 9 different drive speeds keeping the object within the telescopes Freedom from Ghost images even when stacked.

    The Zhumell 2in. 2x ED Barlow doubles the magnifying power of any eyepiece used in conjunction with it. ED optical lenses offer unparalleled image quality and contrast. Many other manufacturers use standard optical glass in their Barlow lenses an accessory which if not designed correctly can diminish the starlight which reaches your eye. The ultimate extension of your eyepiece collection the 2in. 2x Barlow Lens from Zhumell doubles the power of any eyepiece it is used with without sacrificing light transmission. Once you use the Zhumell 2in. 2x ED Barlow you will clearly see why it is an essential part of any eyepiece and accessory collection. Fits 2in. format telescopes and 2in. and 1.25in. format eyepieces. Compression Rings in both the 2in. format and 1.25in. format for protection of eyepieces.
