As a visual instrument, EdgeHD optics deliver pinpoint images even with your widest field eyepiece. You can search for all of the Messier Catalog objects, and see hundreds of other NGC, IC and Caldwell objects with amazing clarity. For astro imaging, 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 stars to be in tight focus to the very edge of the chip. Learn more about the benefits and features of this new optical system by going to the EDGEHD WEB PAGE. INTERNAL GPS The CPC Deluxe HD Series' internal GPS receiver automatically downloads the date and time from orbiting satellites and pinpoints its exact location on Earth. This eliminates the need for you to manually enter the date, time, longitude and latitude. CELESTRON'S REVOLUTIONARY SKYALIGN Once the CPC's internal GPS has established the telescope's position, aligning the telescope is as easy as 1-2-3! Simply locate and use the hand control to manually point (slew) the telescope to three bright celestial objects. You do not need to know the names of the stars. You may even pick the Moon or bright planets! Celestron's NexStar™ software technology will model the night sky to determine the position of every star, planet and celestial object above the horizon. Once aligned, the remote hand control allows direct access to each of the celestial catalogs in its user-friendly database. CELESTIAL OBJECT DATABASE The CPC database contains over 40,000 celestial objects including Messier objects, the Caldwell Catalog, as well as NGC Galaxies, nebulae and planets. User-definable filter limits make navigating through this expansive database quicker and easier. Filter Limits let you filter out objects that are outside of your local horizon (ie, if trees or mountains were in the way). There's also "Solar System Align" that lets you align on the Sun or Moon for daytime observing – it is easy to use this to see planets or bright stars in the day. FASTAR VERSATILITY All EdgeHD optical tubes are equipped with a removable secondary mirror for fast f/2 CCD imaging. Not only does imaging in the FASTAR configuration allow for exposure times that are 25 times faster than at f/10, but also yields a field of view five times wider. A perfect combination for imaging your favorite wide field objects in a fraction of the time. (FASTAR imaging requires a third party lens assembly in place of the secondary mirror). INNOVATIVE FEATURES DESIGN - With the introduction of the CPC Deluxe HD series, Celestron has gone back to the drawing board and re-designed and re-engineered the drive train with a larger 6 inch, 180 tooth brass gear and .75" stainless steel worm gear and unique roller bearing design with both Steel and Nylon ball bearings rotating around a wide 9.8 track designed for smoother tracking accuracy for long exposure astrophotography. INNOVATION - The CPC Deluxe HD series uses the innovative All-Star™ Polar alignment procedure. Coupled with Celestron's optional Pro Wedge, All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CPC, sure to please astro imagers, is the Permanent Periodic Error Correction (PEC), which allows users to train out the worm gears periodic errors, while the mount retains the PEC recordings. POWER MANAGEMENT - Redesigned electronics deliver constant regulated power to the motors making them capable of driving the telescope, even when not perfectly balanced, without sacrificing smooth tracking motion and pointing accuracy across the entire sky. PERFORMANCE - For objects near the Meridian (imaginary line passing from North to South), the CPC will track continuously through the Meridian for uninterrupted imaging through the most ideal part of the sky.

TS Optics f/6.3 Reducer and Corrector for Schmidt-Cassegrain Telescopes This high-quality corrector system was especially developed for SC telescopes. With this 4-element system, you can make a fast telescope for astrophotography out of your SCT. Features and applications of the corrector: The corrector fits to all Schmidt-Cassegrain telescopes from Celestron and Meade. It is simply screwed to the 2" thread at the back of the telescope. At the eyepiece side, the f/6.3 corrector also has the SC thread. You can use your accessories as before. The optimal working distance from the SC thread of the corrector is 85 mm. You can exceed or under-run this distance by 15% without appreciable loss of quality. The focal length of the SC telescopes is reduced with the factor 0.63 - 2000 mm become 1260 mm focal length. The speed is considerably increased. You achieve the same saturation with only 40% exposure time, compared to the photography without corrector. The optical correcture system flattenes the curved field of the Schmidt-Cassegrain telescope, offering a fully corrected image area of 24 mm diameter. The corrector offers an improvement also visually, the sharpness at the edge is enhanced and the yield of true field of view is obvious. We recommend to use the corrector with 1.25" eyepieces. Adaption of the SC corrector to 2": Many amateur astronomers use a separate focuser at their SC telescope for more precise focusing and avoid mirror shifting.
Omegon f/4 astrograph - for unforgettable astronomy photosWhich other type of telescope can be used to create a beautiful image with so little effort? With Omegon astrographs this is easier than with ’ordinary’ telescopes. Why? The answer is obvious - because an aperture ratio of f/4 means a big light output and consequently shorter exposure times. Immerse yourself in the world of deep sky photography. Admire faint galaxies or details in hydrogen nebulae. The Omegon astrograph sets a new benchmark for your astronomy photos.The advantages in a nutshell f/4 astrograph - a telescope with ultra-fast aperture ratio for short exposures suitable to go on medium mountings due to its short overall length wide field of view for extended objects - approx. 24mm is illuminated 94% reflection parabolic main mirror for bright images large secondary mirror - good illumination for DSLR cameras robust 2” Crayford focuser with 1:10 reduction and 1.25” reducer faster cool-down for getting started observing quicker - main mirror fan 94% reflection f/4 main mirrorAstrographs are suitable for visual observing, but only show their full potential when used for astrophotography. Their f/4 aperture means they are among the ’fastest’ Newtonian telescopes around, allowing you to take shorter exposure images.The secondary mirror and the parabolic BK7 main mirror are 94% reflective, providing brighter and higher contrast images. One can see a visible improvement when compared to a ’normal’ mirror which is around 88% reflective. No shadows, only light - large secondary mirrorAttach your DSLR camera or a modern CCD camera to the telescope and enjoy impressive illumination over a wide field of view. No shadowing is noticeable thanks to the particularly large secondary mirror (see also below). Observing with 2” wide-field eyepieces is now perfect. Less mistakes - more fun with the photographyThe particularly short OTA length and focal length means the telescope is compact - the astrograph is about 20% shorter as compared to an f/5 system. This means you can also use this OTA’s excellent optics on a medium mount, saving yourself the expense and clumsiness of a heavier mount.Another advantage is that the astrograph is perfect for extended deep sky objects thanks to its shorter focal length. This system is also more tolerant of small tracking errors than a telescope with a longer focal length. You will achieve some astounding astrophotography with even just a little effort. 3” focuser with linear ball bearings - illuminate huge fields of view Instead of using classic ball-bearings this eyepiece has a ’Linear-Power-System’. The advantage is that a stainless steel rail makes the focuser much more stable. Your equipment will not tilt or slip. The 72mm inner diameter of the focuser tube provides shadow-free illumination for large and fast telescopes. It is even suitable for full-frame sensors. It is the right focuser for your large field camera. In comparison, a 2” focuser would show unsightly shadowing on the edge of the image - a 3” focuser means more freedom for large and extended images, and that’s just how it should be! Of course, this focuser has even more features dual rate 1:10 reduction assists you in accurately focusing astronomical objects. - a 2” to 1.25” adapter is included for all eyepieces and adapters laser-engraved scale to help you find a previously used focus position only 82mm long and with 50mm of adjustment 74x0.5mm thread for adapter or filter wheel friction adjustment length 82mm Get started observing faster - main mirror fanJust a quiet, unobtrusive hum, but what an effect! - the built-in 12V fan means 50% faster cool-down of your main mirror.
