Celestron 5" Omni XLT Schmidt-Cassegrain OTA
What versatile telescope! With Celestron's 5" Omni XLT Schmidt-Cassegrain telescope posted on a camera tripod or other lightweight alt-azimuth mount, you'll enjoy the ultimate in portability. Make it your travel telescope for astronomy, or add an erect image diagonal and turn the 127 SCT into an amazing spotting scope for daytime use. Add a simple camera adapter and DSLR camera and do photography (daytime or nighttime) by using the scope as a 1250mm, f/9.84 lens! If you want to use this telescope for night-time observing, then mount it on an equatorial mount so that it can track the movements of the stars...and if you choose a GoTo model, your telescope will find objects for you with the click of a button.
About Celestron Schmidt-Cassegrain Telescopes
Celestron’s excellent Schmidt-Cassegrain telescopes are compact and portable and represent the best all-purpose design for a wide variety of uses from terrestrial and deep sky viewing to astrophotography.
Catadioptrics use a combination of mirrors and lenses to "fold" (reflect) the light path and form an image. In a Schmidt-Cassegrain, the light enters through a thin aspheric Schmidt correcting lens. It then strikes the spherical primary mirror. It is reflected back up the tube and intercepted by a small secondary mirror which reflects the light out an opening in the rear of the instrument where the image is formed at the eyepiece.
Catadioptrics are the most popular and most modern type of telescope optical design and are marketed throughout the world in 3.5" and larger apertures. Catadioptric telescopes combine the practical advantages of lenses and mirrors while eliminating their disadvantages. They offer the clarity and contrast of refractors with the low aberration of reflectors. Catadioptrics have an average focal ratio of f/10, which is wide enough for all types of photography. They are also easier to maintain because all optical elements are solidly mounted and rigidly collimated. Catadioptric telescopes provide the best possible combination of light gathering power, long focal length, portability, and affordability.
