Celestron CPC Deluxe 925 EdgeHD GoTo Telescope

... opening 235mm / focal length 2350mm on modern azimuthal GoTo mount


The CPC Deluxe 925 HD combines the reworked fork mount with the new EdgeHD look.

It's the favorite of many astrophotographers because it collects 33% more light than the 8 "model and provides excellent sharpness, as well as being highly portable and providing good stability even with the optional pole height cradle.


The innovations of the CPC at a glance:

+ Highly corrected EdgeHD optics for maximum sharpness for visual and photographic use
+ Main mirror detection and active ventilation to reduce cooling time
+ fully computerized azimuth mount with tracking
+ 15cm brass gear with 180 teeth / stainless steel screw for high-precision tracking
+ Improved ball bearing of the axles
+ with the optional pile height cradle, the CPC can be accurately nested on EVERY star; Neither Polsucher nor a clear view of the Polarstern are necessary
+ optimized voltage - even if the telescope is not even balanced, the motors are always supplied with sufficient current for accurate adjustment.
+ solid stainless steel stand for optimum rigidity



The EHD optics - the new design:

The EdgeHD optics (Edge High Definition) combine the compact design of a Schmidt-Cassegrain with significantly improved image at the edge of the image. This optical system not only provides astrographic properties, but also produces totally undistorted, sharp images to the edge (= "edge") of the large visual and photographic field of view. Not only the coma outside the optical axis, but also the field curvature is corrected. All EdgeHD telescopes provide a large flat field of view, which also provides a sharp star image at the edge of large CCD sensors.


Built-in GPS:

The CPC Deluxe HD Telescopes have a built-in GPS sensor that automatically receives the date, time and location from the GPS satellites. This eliminates the need to enter this data manually.


SkyAlign - Extremely simple oak of the telescope

is the name Celestron's alignment method for perfect GoTo positioning. The telescope does not need a defined basic position any more: Simply three successive bright stars (also planets and the moon are possible) are set in the field of view of the telescope and immediately the CPC telescope is ready for automatic GoTo positioning on any object from the database of the hand control ,

From the routes of the three stars and the corresponding angles SkyAlign calculates the installation of your telescope. The additional data required for this (date, time, and location coordinates) "gets" SkyAlign via the integrated 16-channel GPS receiver.

"SkyAlign" works only in azimuthal operation of the telescope, so if the telescope without polar height cradle is operated directly on the tripod. But also for parallactic operation, Celestron has some new and simplified alignment techniques in the CPC series.


Extensive database:

The CPC telescope database contains more than 40,000 celestial objects, including the Messier and Caldwell catalogs, 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 under the horizon.

The "Identify" feature tells you what you are seeing in the telescope and lets you easily explore the sky with it. Just point the telescope at any area of ​​the sky and let's you see the next Messier objects, for example - the telescope will use them for you. You can do that in different sky areas and with different objects!

With "Solar Sys Align" you can also align the telescope during the day with the help of sun or moon to observe the planets or the brightest stars in the daytime sky.

Hyperstar compatible With all EdgeHD tubes, you can remove and replace the secondary mirror. The result: Your standard Celestron EdgeHD telescope with the optional HyperStar optics, a digital Schmidt design for your CCD or DSLR camera for primary focus photography at f / 2 (C8, C11), f / 2.3 (C925) and f / 1.9 (C14).
