Celestron Schmidt-Cassegrain SC 203/2032 Telescope NexStar Evolution 8 HD StarSense

Evolution: The next step in portable telescopes!

Integrated WLAN module: Instead of using the manual control box, you can also control the NexStar Evolution wirelessly with your iOS or Android smartphone or tablet. Use the free Celestron SkyPortal app, including the planetarium view and SkyAlign! Of course, you can also operate the telescopes in the classic way using the NexStar hand control.

Lithium Iron Phosphate (LiFePO4) Battery: Forget the clutter of cables or carrying around an expensive "power tank"! The built-in (but replaceable) battery powers the telescope for one night (ten hours) and even allows you to charge your smartphone via a USB port. You can recharge the built-in battery with the included power supply.

Even Better Ergonomics: The innovative product design introduced by Celestron with CPC telescopes can now be found on NexStar telescopes as well. In addition to the reinforced drive, this includes many "little things" that make observing more pleasant: A very stable tripod whose accessory tray does not have to be removed to fold it completely. The tripod legs have indentations so you can extend the legs by the same amount. The tabs on the thumbscrews point inward so you don't get snagged in the dark. The mounting table serves as an eyepiece tray and has been provided with a rubber pad for this purpose. The very subtle red light helps you find your accessories safely. Thanks to the carrying handle on the fork leg and the handles around the base of the fork, handling is very easy and comfortable.

Celestron EdgeHD optics: corrected image, sharp to the edge!

EdgeHD is Celestron's optical design designation, the "Aplanatic Schmidt-Cassegrain Telescope." After more than 50 years of success, Celestron is revolutionizing the classic Schmidt-Cassegrain telescope.

EdgeHD (English: "Edge High Definition") telescopes are true astrographs. This optical system delivers sharp, distortion-free images right to the edge of the field of view. Not only is coma corrected off the optical axis, as with other so-called "coma-free" optical designs available on the market, but also curvature of the field.

Many optical systems are propagated as "astrographs". They obtain images of stars with the desired precision, but along a curved image plane. When taking pictures with cameras, the result is a striking field curvature that increases towards the edge of the field and is all the more noticeable the larger the sensor. The stars inflate into small rings ("doughnuts") towards the edge. In addition to coma, Celestron Edge HD telescopes also correct for this curvature of field all the way to the edge. This also significantly improves resolution and cut-off size compared to competing optics with a similar aperture.

Celestron's XLT multi-coating also helps EdgeHD optics achieve a significant increase in performance compared to similar systems on the market.

The mechanics and tube of the Edge HD telescopes have been completely revised:

Mirror locks hold the main mirror in any focus position without putting pressure on the optical elements. The image always remains stable on the chip, even with long exposure times.

The ventilation openings behind the main mirror ensure rapid air exchange, so that the optics cool down quickly without equal. Thanks to an air filter system, no dust enters the tube.

StarSense AutoAlign: This technology is revolutionizing amateur astronomy!

With azimuth-mounted telescopes, thanks to StarSense, alignment is possible without GPS, without entering coordinates, without aligning and leveling to north, and without cumbersome star positioning. Within three minutes, the telescope is ready for use without user intervention, without prior knowledge of stars and astronomy. Just turn it on, wait three minutes, and you can zoom in on all celestial objects with the touch of a button!

The StarSense module also brings great benefits when combined with equatorial mounts. A polar adjustment is still required, but with Celestron's new "AllStar" procedure, this can be done on every star in a few minutes! Simply enter the location and time, select the star from the database and move towards it, then use the azimuth and altitude adjustment to bring it into the crosshairs. Finish! After that, StarSense can use the fully automatic "3 minute plate resolution process" to set the exact orientation without any additional user input, just like with azimuth mounts. The cumbersome and tedious focusing and centering of guide stars is no longer necessary.

Another advantage of StarSense is the extreme improvement in positioning accuracy using the T-Point method. Similar to some high-end mounts, you can "map" any number of stars, ie zoom in on them, place them exactly in the middle of the scope, and confirm the exact position with "Enter". From ten mapped stars (which should be distributed throughout the visible part of the sky), the positioning accuracy becomes extreme.

The secret to StarSense technology is a small camera module that attaches to the telescope like a viewfinder. It takes 3 wide-angle photos of different areas of the starry sky, the StarSense handheld controller analyzes these photos and uses them to calculate the position of the other objects in the starry sky. This is the first time Celestron has brought this professional technology, known as "plate resolve," to the market at a price affordable to amateur astronomers.

The StarSense Module comes with the StarSense Hand Controller.

The StarSense module can be used on almost all azimuth and equatorial mounts with GoTo technology from the last 10 years, for example, Nex-Star GPS series telescopes.

Also included in delivery: two finder bases, suitable for the small dovetail rail of Celestron/Vixen/Skywatcher telescopes, or suitable for large Schmidt-Cassegrain.

The StarSense hand controller replaces the previous hand controller. It offers the same features plus StarSense alignment and multi-star calibration for one mount model. Same as him NexStar hand controller, the StarSense hand controller can also list different objects by catalog or be used to connect to a PC.
