    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). Farpoint Dovetail Plate System for Celestron SCT Telescopes, Curved Blocks and hardware for the Celestron SCT telescopes. Mounts to existing holes on the telescope tube. Our dovetail plates are compatible with Losmandy style dovetail accessories! Farpoint dovetail plates have machined fillets, chamfered corners and edges for a finished look. A short taper at each end of the dovetail portion of the bar makes insertion into the saddle easier. To reduce weight and maintain rigidity, the aircraft grade aluminum plate is pocket milled on the back side. The dovetail plate and curved blocks are black anodized and include stainless steel attachment hardware. 8 Inch Plate:Length: 13.5 Control your telescope from your PC!No more confusion! Finding stars and other celestial objects with your Meade ETX 90/105/125/LX90 telescopes is now easier than ever before. The Meade #505 AstroFinder software/connector cable kit allows you to control your telescope from a PC. Load the AstroFinder software into your computer and your #497 Autostar equipped ETX telescope can be remotely controlled from the PC's display. Simply point and click your way to any object on the computer screen and the telescope will automatically slew around and place the object in your field of view. Truly star finding has never been so easy or rewarding! Kit Includes:The #505 6 foot connector cable and A DB 9 serial adapter for connection to a PC or laptop.The kit works with all Meade ETX 90/105/125 telescopes that use the #497 Autostar controller.  Compatible with Windows 98 ME 2000 XP Vista and 7 Telescope and spotting scope vibration can be caused by windy conditions an unsteady mount or a simple bump. Whatever the source though reduced image quality results. Celestron's set of three vibration suppression pads gets the shakes out. It'll reduce vibration time by almost 100 percent while decreasing vibration amplitude and that translates into better image quality. The pads fit between the tripod's feet and the ground providing a simple functional vibration damper. They work on any surface: grass dirt concrete asphalt wood etc. for both telescopes and spotting scopes. And they banish image bounce forever! This Quality Meade 90 degree diagonal prism is for Schmidt Cassegrain and refractor telescopes. The image will appear upright but mirror reversed. The advanced in Advanced Coma Free. A traditional Ritchey Chrtien (RC) is a type of reflector that delivers a coma free flat field of view via hyperbolic primary and secondary mirrors. Because the mirrors in these telescopes have always been very expensive to make few amateur astronomers could enjoy them. Fortunately Meade engineers developed a radical new Advanced Coma Free design by combining a hyperbolic secondary mirror with a corrector lens and spherical primary mirror combination that performs as one hyperbolic element. This ACF design produces a coma free flat field of view that rivals traditional RC telescopes at a fraction of the cost. The design even eliminates diffraction spikes and improves astigmatism both of which are inherent in the traditional RC design. When reviewing Meades LX400 ACF Advanced Coma Free Sky and Telescope magazine said  [It] does indeed perform like a [Ritchey Chrtien]. The difference between the off axis images (compared to a Schmidt Cassegrain) was dramatic to say the least.Meade Ultra High Transmission Coatings (UHTC) increases total light transmission and image brightness by nearly 20% over Meades standard coatings. Objects such as stars galaxies and nebulae will appear significantly brighter. Not just another colored filter. Finally a set of serious tools for the planetary observer. Baader Planetarium's Premium Colored Filters bring a new level of quality and performance to planetary contrast enhancement. Available singly or as a full set of 6 filters.    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).  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).  With the new 2 inch size only one filter is needed for binoviewing. Only Baader colored filters have the optical quality necessary for use this far ahead of the focal plane. Alt Az Computerized mount as supplied with all NexStar 6/8 telescopes  NexStar technology with database for automatic slewing (GoTo) and tracking of 40000 objects  Flash upgradeable hand control with SkyAlign alignment procedure and NexStar technology  NexRemote telescope control software  RS 232 cable  Steel Tripod  The Sky X First Light Edition CD ROM CPC 925 GPS XLT  Unique design advanced features GOTO accuracy and superb optics. You get the picture.     Celestrons 9.25 optical system has enjoyed a loyal following since we first introduced it with our Ultima 9.25 in 1995. Now the 9.25 optical tube is coupled with Celestron's newest computerized telescope family  the CPC GPS series.     The 9.25 was already a favorite among astrophotographers and discerning visual observers and it offers 33% more light gathering than our 8 model. The CPC 925 GPS XLT was specifically designed for visual infinity focus when using 2 eyepieces and has an optimized baffle system to benefit astrophotography by minimizing vignetting at the edge of the field of view. Its longer primary focal length and lower magnification secondary mirror contribute to a flatter field of view at the focal plane and helps to further reduce optical aberrations.     This feature packed model comes standard with Celestron's renowned StarBright multi coatings. The CPC 925 GPS is compatible with the complete line of Celestron photographic and visual accessories.     What makes the CPC 925 GPS XLT great for astrophotography?       Longer focal length primary and lower magnification secondary Contributes to a flatter focal plane with less coma and off axis astigmatism.  Baffle design Optimized for astrophotography. Minimizes vignetting at the edge of the field of view. This reduces light drop off at the corners of your film plane.  Hand Figured Optics  Just like all other Celestron Schmidt Cassegrain telescopes the CPC 925 GPS optics are individually matched and hand figured to ensure the highest optical quality in every telescope.  Focus mechanism  At the heart of Celestron's Schmidt Cassegrain focus mechanism are pre loaded ball bearings not bushings minimizing focus shift.  Heavy duty die cast aluminum fork arms For maximum rigidity.
