Celestron CPC Deluxe 925 HD Computerised Telescope

Celestron's 925 optical system has enjoyed a loyal following since its first introduction in 1995. Now the 925 optical tube is even better with the addition of EdgeHD optics. The CPC Deluxe 925 HD is a favourite among astro imagers and discerning visual observers with it offering 33% more light gathering than the 8 inch model. Specifically designed for astro imaging and optimized to reduce aberration across a wide field of view. This feature packed model comes standard with Celestron's renowned StarBright XLT multi-coatings.

Celestron CPC Deluxe 925 HD:

New Optical Design: The EdgeHD optical system combines all of the compact power popularized by the SCT with an improved high definition optical system for wide field, astrograph quality images. As a visual instrument, EdgeHD optics deliver pinpoint images even with your widest field eyepiece. You can search for all of the Messier Catalogue 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 favourite 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.

What makes the CPC Deluxe 925 HD unique for astro imaging? Longer focal length primary, and lower magnification secondary, creates a focal plane nine times flatter than a traditional Schmidt-Cassegrain with less coma and off-axis astigmatism. Internal 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 image plane.

Internal GPS: The CPC 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 catalogues in its user-friendly database.

Celestial Object Database: The CPC database contains over 40,000 celestial objects including Messier objects, the Caldwell Catalogue, 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).

Luminos Eyepiece: The CPC Deluxe 925 HD comes with Celestron's top of the line, wide field eyepiece. With a 23mm focal length and 82 degree AFOV, you get an incredible combination of power and wide field of view. Plus each Luminos eyepiece is optimized to deliver pin point images when used with a flat field telescope.

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 favourite 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.
