OVER 60 YEARS OF INNOVATIVE TECHNOLOGY

In the 1960s, Celestron’s founder, Tom Johnson, created groundbreaking new telescopes never before seen on the consumer market. Today, our world-class team of optical and electronic engineers continues to push the boundaries of technology. From the SkyProdigy, a telescope so smart it can align itself, to our high-performance EdgeHD optical system, we’ve revolutionized the hobby of astronomy for beginners and advanced amateurs alike. Go behind the scenes with Celestron’s product development team and learn more about our award-winning and patented innovations.

At the forefront of a new era in amateur astronomy, the launch of Celestron Origin stands as a beacon, seamlessly intertwining stargazing and astrophotography into a singular, user-friendly experience. This intelligent, all-in-one observatory and astroimaging system emerges as a catalyst, eliminating the complexities traditionally associated with telescopes and, in turn, metamorphosing your backyard into an inviting gateway to the Universe.

Celestron released the patented Rowe-Ackermann Schmidt Astrograph (RASA) 11” optical tube in 2014. Unlike traditional telescopes, the RASA design ingeniously places the imaging sensor at the front of the telescope tube, creating an ultra-fast f/2.2 system with an extraordinarily wide field of view.

Celestron’s aplanatic EdgeHD optics revolutionized astroimaging. This award-winning optical system reduces visual defects like field curvature and coma, creating an ultra-flat field for pinpoint stars all the way to the edge of today’s largest imaging sensors.

Learn More

Fastar Technology allows imagers the option of drastically increasing the speed and sensitivity of their Celestron optical tube, allowing bright, detailed images with short exposures.

Learn More

Our patented SkyAlign alignment technology makes setting up a computerized telescope simple, fast, and accurate. Just point the telescope at any three bright objects—stars, bright planets, or even the Moon—and your telescope can orient itself with the night sky.

Learn More

Celestron’s patented StarSense® Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before. Turn it on and push ‘Align.’ In about three minutes, you’re ready to observe!

Learn More

Get ready for a night of astroimaging with your mount faster than previously thought possible with All-Star Polar Alignment. This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole.

Learn More

One of the most important factors in a telescope is its transmission—the percentage of light that reaches the focal plane. Our proprietary StarBright XLT optical coatings dramatically increase transmission, up to 97.4% on our Schmidt corrector lenses.

Learn More

ED stands for "extra-low dispersion," which refers to the composition and optical properties of the glass used for the lenses. ED glass is specially formulated and contains rare-earth compounds that greatly reduce a visual defect called chromatic aberration.

Learn More

This telescope control software replaces the hand control and allows the user to remotely control their Celestron computerized telescope from their personal PC or laptop.

Learn More

EclipSmart solar products feature Solar Safe filter technology providing the ultimate protection from harmful solar radiation, including both IR and UV light, and filters 99.999% of visible light. Celestron Solar Safe filter technology is GUARANTEED SAFE for direct solar observation and has been independently tested by SAI Global Assurance Services.

Description

The 1-1/4" OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects.

Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700nm This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.
