Regular catadioptric designs like Schmidt-Cassegrains often have a curved focal plane which causes aberration on the edge of the field of view, especially when imaging. Since corrector lenses are used in conjunction with mirrors, the EdgeHD optical system designed by Celestron aims to fix this issue by creating the focal plane three times flatter than traditional Cassegrain designs, therefore creating pinpoint stars even at the edge of the field of view. Usually, stars at the edge of the field of view will appear as donut shaped blobs but with the introduction of EdgeHD, they're pinpoint and high resolution. For astrophotographers, this allows the largest CCD sensors to be used. When used in conjunction with the optional reducer lens (purchased separately), exposure time can be cut in half and the field of view can be increased by 43%, making the telescope for suitable for deep sky imaging of galaxies and nebulae.
The dual fork mount is a fully computerized altazimuth mount that uses the NexStar computer control technology. The Sky Align feature allows the observer to align to three bright stars, providing a very fast alignment. Once aligned, there are 40,000 objects to choose from in the NexStar database. For imaging, periodic error correction (PEC) helps reduce errors from the irregularity in shape of the motor worm by recording irregularities and playing them back to minimize the errors. This assists in astrophotography because it prevents trailing of stars. For more improvement, PEC software is also available and can be used with the normal mount built in PEC features for better quality.

Remote-controlled imaging telescope will play a key role in NASA’s SERVIR mission to further environmental research.
International Space Station (January 18, 2013) – The astronauts aboard the International Space Station (ISS) just got that much closer to Earth with their latest crew member: a Celestron CPC 925. After arriving at the ISS in July 2012 onboard the Japanese HTV-3, the telescope—the latest component of ISERV (ISS SERVIR Environmental Research and Visualization System)—officially joined Expedition 34 and NASA’s SERVIR mission on Wednesday, January 16.
Canadian astronaut Colonel Chris Hadfield enthusiastically announced the installation of ISERV on his Twitter account: “Taking the telescope out of the box—like weightless Christmas!” Accompanying the tweets was a photo of the telescope floating next to Col. Hadfield’s beaming visage.
Celestron's 9.25” diffraction limited Schmidt-Cassegrain telescope is positioned within the Destiny module’s Earth-facing window. While remotely controlled from the planet’s surface, ISERV will monitor and assess environmental disasters, climate change, rainforest destruction, and air quality in various locations around the globe. It will also aid in short-term weather prediction.
“Images captured from ISERV on the ISS could provide valuable information back here on Earth,” explained Dan Irwin, SERVIR program director at Marshall Space Flight Center. “We hope it will provide new data and information from space related to natural disasters, environmental crises, and the increased effects of climate variability on human populations."
“ISERV will help advance Earth science research. We are all very excited and proud to see Celestron’s telescope assisting NASA’s quest for knowledge,” explained Corey Lee, Senior Vice President of Product Development at Celestron.
