Jims Mobile MOTOFOCUS for Celestron 14 Inch CGE Telescope JMI Medium Size Universal Wheeley BarsAdjusts to fit tripods with tip-to-tip distance from 33 Celestron's Nightscape CCD camera combines the simplicity of a one-shot color imaging camera with the sophisticated features and software of more expensive astronomical imaging systems. Using a Kodak 10.7MP Color Sensor and regulated TEC cooling system Nightscape can give you instant results in just a single exposure. Coupled with the internal mechanical shutter and control software you can also automatically combine multiple images and dark frames to create images comparable to those taken with professional grade cameras costing thousands more. With Nightscape you get: Versatility With compact 4.75 micron x 4.75 micron pixels and 2x2 and 4x4 binning the Nightscape is perfectly matched for optimal resolution at multiple F-numbers. With an F/10 system and 2x2 binning Nightscape gives you a large image scale while still providing sub-arc second image sampling; ideal for bringing out fine detail in planets and compact deep-sky objects. Or take advantage of the high resolution 4.75 micron x 4.75 micron pixels at f/2 to capture your favorite wide field objects while maintaining resolution better than your seeing conditions. Nightscape gives you the versatility to match all the configuration of your EdgeHD SCT or other optical system. Fidelity The Kodak KAI-10100 Color Sensor offers both light sensitivity and a balanced spectral response for capturing true color fidelity in a fraction of the time as with a color filter wheel. Cooling Regulated Thermoelectric Cooling (TEC) and variable fan control provides a vibration free laminar air flow to dramatically reduce thermal noise inherent in all imaging sensors. Form Factor Compact four inch diameter design provides minimal obstruction needed for Fastar f/2 imaging. The round symmetrical aluminum cast body resembles the obstruction of the secondary mirror of a Cassegrain telescope ensuring round star with minimal light diffraction. Additionally the spacing to sensor is the same distance as m Get Stellar land views! Celestron's #94112A erect-image diagonal offers out-of-this-world views of land objects. It features an Amici prism design that allows you to look into the telescope at a comfortable 45-degree angle at images that are oriented properly - right-side-up and non-mirrored. The Celestron #94112A erect-image diagonal: it brings stellar views down to earth! Meade Series 4000 Filters Color filters are essential for observing and imaging the moon and planets in tantalizing detail. The right filter can mean quite literally the difference between seeing several small craters in the floor of Clavius on the moon or not; seeing five or six swirls in Jupiter's north equatorial belt or not; seeing the inner crepe ring of Saturn or not. Depending on atmospheric conditions on Earth and the planet being observed (or photographed) the advantage of color filters can be anywhere from subtle to dramatic. Meade Series 4000 filters offer 26mm of clear aperture and are manufactured from the purest optical glass dyed-in-the-mass (not color coated) There are no finer filters available for telescopic applications. They thread into the barrels of virtually any brand of 1.25 eyepiece as well as the 1.25 Meade Basic Camera Adapter. They may also be stacked to achieve selective filtration of the visual color spectrum. Each Series 4000 filter is packed in a foam-fitted plastic case for safe long-term storage. #12 Yellow (74% Transmission) Adds contrast to blues and enhances reds and yellows on Jupiter and Saturn increases contrast on Mars and the moon (in scopes 6 plus) #23A Light Red (25% Transmission) Enhances detail in polar regions of Jupiter Saturn and Mars (in scopes 6 plus). Also increases contrast between Mercury and evening sky. #58 Green (24% Transmission) On telescopes 8 plus this green increases belt structure on Jupiter and Saturn's surface and in Saturn's rings. Also enhances Mars' ice caps. #80A Blue (30% Transmission) A popular filter for enhancing spiral features in Jupiter's cloud belt (including Red Spot) and adding contrast to Saturn and the moon. #11 Yellow-Green (78% Transmission) Contrasts with red and blue features on Jupiter and Saturn. Darkens the maria on Mars. Clarifies the Cassini division in Saturn's rings. #25A Red (14% Transmission) Dark red bl The Celestron Omni XLT 102 Refractor Telescope features an innovative design and high-quality optics which combine to make it an excellent tool for astronomy and astrophotography. Its refractor telescope design makes it sturdy easy to use and easy to clean and care for. Additionally this model features simple no-tool assembly.Only the finest grade of glass is used in the Celestron Omni XLT's hand-selected and hand-figured mirrors and lenses. StarBright XLT multi-coatings and a generous 120mm objective lens allow for optimum light transmission. The 25mm eyepiece features 20mm eye relief making it comfortable even for those who wear glasses.Additionally this telescope features a CG-4 German Equatorial Mount with setting circles and slow-motion controls to aid in accurately locating and tracking sky objects. Ball bearings in both axes of the mount allow for better control and smooth performance.Model includes a heavy-duty pre-assembled stainless steel tripod with 1.75-inch legs an accessory tray a bubble level and Baader 2 Herschel prism for non-compromised solar observation. A new technology for light and heat absorption. Includes 2 Solar Continuum filter. The Baader Herschel prism's mode of operation The sunlight enters the telescope unfiltered. On the back side 4.6% of the light are deflected by 90 degrees. The rest of the light is focused outside the Herschel prism. This light's energy is very high and cannot be used for observation. The Baader Cool Ceramic Safety Herschel Prism offers the best solution: A special ceramic developed for space technology accepts the light energy without heating its environment so the prism housing can be kept closed and the risk of glare or fire is eliminated. Easy positioning of the sun A smart side effect of this ceramic screen is the possibility of centering the sun in the telescope easily. Just place the sun spot in the middle of the ceramic screen and you can start observing Both the Visual and the Photo version contain the same Herschel prism. The difference lies in the different filter equipment. The Visual model includes the 2 Neutral Density ND 3.0 and 2 Solar Continuum Filter. The Photo version includes four 2 Neutral Density (ND0.6 / 0.9 / 1.8 / 3.0 and the 2 Solar Continuum Filter. What kinds of telescopes can be used with the Herschel prism? The Herschel prism is intended for frefractor telescopes without field flattener lenses on their back side. The objective design (Doublet Triplet Air-Spaced etc.) is not important. For all other kinds of telescopes we recommend a standard aperture covered solar filter. The Celestron CGEM 925 HD combines Celestron's newly designed CGEM Computerized Equatorial mount with its new EdgeHD optical system. With over 9 inches of aperture and our premium StarBright XLT coatings the CGE Pro 925 HD gives you over 1000 times the light gathering power than the unaided eye. Designed to give difraction limited performace the CGEM 925 HD has established itself as a premier astro-imaging telescope. New Optical Design The EdgeHD optical system combines all the compact power popularized by the SCT and combines it with an improved high definition optical system for wide field astrograph quality images. As a visual instrument EdgeHD optics delivers pinpoint images even with your widest field eyepiece. You can search for all of the Messier Catalog objects and see hundreds of other equally interesting NGC IC and Caldwell objects with amazing clarity. For astroimaging the EdgeHD optics produce aberration-free images across your favorite CCD or DSLR camera. All EdgeHD optics are designed to produce an extremely flat focal plane precise enough to match the strict tolerances of the largest commercial ccd detectors allowing all stars to be in tight focus to the very edge of the chip. Diffraction Limited Some companies boast that their telescopes give diffraction limited stars in the very center of the field of view. EdgeHD optics not only produce diffraction limited stars on axis but maintain diffraction limited stars across the entire field of view of many of the most popular astrophotography cameras. Even at the very edge of a DX format camera chip the EdgeHD 9.25 delivers star sizes of only 1 arc second. Along with the newly designed optics the EdgeHD also has re-designed mechanics guaranteed to help you get the maximum performance from your instrument. Features Include: Mirror Locks To hold the mirror in place and reduce image shift during imaging. Tube Vents - Each vent has an integrated 60 micron micro-mesh
