Product description for Celestron CPC 925 SC

Celestron's 9.25" optics have had a loyal following since their market launch with the Ultima 9.25 in 1995. Now this Schmidt-Cassegrain is also available with the latest series of computer-controlled mounts, the CPC GPS system

The 9.25" is popular with both photographers and visual observers and collects 33% more light than the 8" model. The optics have been specially calculated for observations with 2" eyepieces and have an optimized aperture system to minimize vignetting at the edge of the image field in photography. Its primary mirror with longer focal length and secondary mirror with lower magnification enable a flatter image and reduce optical aberrations.

The StarBright XLT coating enables particularly bright and clear images.

Why is the CPC 925 GPS particularly suitable for astrophotography?

• Longer focal length of the primary mirror and lower magnification of the secondary mirror - reduces field curvature, coma and off-axis astigmatism.
• Aperture design - optimized for astrophotography and minimizes vignetting at the edge of the image field. This means that the corners
• corners of the camera sensor are better illuminated.
  Hand-picked optics - as with Celestron's other Schmidt-Cassegrains, the optics of the CPC 925 GPS are matched by hand so that each telescope delivers maximum performance.
• Focusing mechanism - two preloaded ball bearings support the Schmidt-Cassegrain's primary mirror focusing to minimize "mirror tilt".
• Unique ball bearings in the mount base - the 28 cm azimuth bearing ensures smooth and stable tracking, even in equatorial setup with polar wedge
• Autoguider connection - you can connect an autoguider for long-term astrophotography
• StarBright coating - high-quality multi-layer coating for maximum transmission and light yield

Professional XLT computer telescopes
With the CPC series, Celestron introduces the most stable fork mount that has been available in the 40 years of production of Celestron Schmidt-Cassegrain telescopes. The completely redesigned tripod and a huge 280 mm ball bearing in the fork base allow vibration-free observation even at the highest magnifications.

The azimuthal fork mount is not as variable as the German mount, as it is matched to the tube diameter. This disadvantage is compensated for by its compact design, low weight, good transportability and, most importantly, incredibly fast set-up. You are ready to observe in just a few minutes. Simply set up the tripod, level it with the built-in circular level, attach the fork mount - and switch it on.

Built-in GPS
The 16-channel GPS receiver transmits the time, date and location coordinates to the electronics. This means you no longer have to enter the time and location yourself - the telescope automatically has the exact data.

SKY ALIGN ...
... is the brand new alignment method from Celestron 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 available 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 just 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.
