New optical design, more options and precise computer control
The Celestron 9.25 has had a loyal following since the Ultima 9.25 was launched last year. With the EdgeHD system, the telescope has become even better. The 9.25 is the favorite of many astrophotographers and collects 33% more light than the 8" model. The CPC Deluxe 925 HD is optimized for astrophotography and corrects image errors over a wide field. Of course, it has the well-known StarBright XLT coating and is compatible with all Celestron visual and photographic accessories.
New optics design
The EdgeHD (Edge High Definition) optics combine the compact design of a Schmidt-Cassegrain with significantly improved imaging at the edge of the image. This optical system not only offers the properties of astrographs, but also produces completely undistorted, sharp images right up to the edge of the large visual and photographic field of view. Not only is the coma outside the optical axis corrected - as with other so-called "coma-free" optical designs available on the market - but also the image field curvature! All EdgeHD telescopes provide a large flat field of view, which enables sharp star imaging even at the edge of large CCD sensors. Further information and sample images can be found on our Edge HD page.
What makes the CPC Deluxe 9.25 HD so unique for astrophotography?
The primary mirror has a longer focal length and the secondary mirror a smaller magnification than conventional Schmidt-Cassegrains. This means that the image plane is nine times flatter than with other Schmidt-Cassegrains. The result: less coma and off-axis astigmatism.
Built-in diaphragm system, optimized for astrophotography - minimizes vignetting at the edge of the image field and enables more even illumination of the entire sensor.
Built-in GPS
The CPC Deluxe HD telescopes have a built-in GPS sensor that automatically receives the date, time and your exact location from the GPS satellites. This means you no longer need to enter this data manually.
SkyAlign
... is the name of Celestron's foolproof alignment procedure for perfect GoTo positioning. The telescope no longer needs a defined home position: you place three bright stars (planets and the moon are also possible) one after the other in the telescope's field of view and voilá, your CPC telescope is ready for automatic GoTo positioning on any object from the manual control database.
SkyAlign calculates the position of your telescope from the distances traveled by the three stars and the corresponding angles. SkyAlign "fetches" the other data required for this (date, time and location coordinates) via the integrated 16-channel GPS receiver.
"SkyAlign only works in azimuthal operation of the telescope, i.e. when the telescope is operated directly on the tripod without a polar altitude cradle. But Celestron also has some new and simplified alignment procedures for equatorial operation in the CPC series.
Extensive database
The database of the CPC telescopes contains over 40,000 celestial objects, including the Messier and Caldwell catalogs as well as galaxies and nebulae from the NGC catalog and the planets. You can narrow down the selection to simplify the search in this comprehensive database and hide the objects that are currently below the horizon.
The "Identify" function tells you what you are looking at in the telescope and makes it easy to explore the sky. Simply point the telescope at any area of the sky and display the nearest Messier objects, for example - the telescope will move to them for you. You can do this in different areas of the sky and with different objects!
With "Solar Sys Align" you can also align the telescope during the day using the sun or moon to observe the planets or the brightest stars in the daytime sky.
Luminos wide-angle eyepiece
The CPC Deluxe 925 HD comes with the modern Luminos wide-angle eyepiece. With a focal length of 23mm and 82° field of view, it offers an impressive combination of performance and field of view. In addition, the Luminos eyepieces are specially designed for telescopes with a flat field of view.
