Celestron 8″ CPC Schmidt-Cassegrain Telescope Ultimate Bundle – 11073-BUN1-T Celestron

Celestron 8″ CPC SCT Ultimate Bundle

The CPC 800 GPS XLT is the most portable of Celestron’s top-of-the-line fork-mounted astronomical telescopes and includes Celestron’s premium StarBright XLT coatings. This telescope is at home as a superb visual instrument or, with optional wedge and CCD cameras, as a serious astrophotographer’s tool.

Turn this scope to planets and see amazing detail on the surface of Jupiter; see Cassini’s Division in the rings of Saturn, and resolve details on the surface of Mars. Even the distant Uranus, Neptune and Pluto are within your reach.

Although large in aperture, with its conveniently located carrying handles and an instrument weight of only 42 lb., this telescope is portable enough to setup in your backyard or take with you to your favorite dark sky location.

 Celestron’s CPC Series with revolutionary SkyAlign Alignment

Technology re-defines everything that amateur astronomers are looking for — quick and simple alignment, GPS, unsurpassed optical quality, ease of set-up and use, ergonomics, enhanced computerization and, most important, affordability.

Internal GPS

The CPC Series’ internal GPS receiver automatically downloads the date and time from orbiting satellites and pinpoints its exact location on Earth. This eliminates the need for you to manually enter the date, time, longitude and latitude.

Celestron’s Revolutionary SkyAlign

Once the CPC’s internal GPS has established the telescope’s position, aligning the telescope is as easy as 1-2-3! Simply locate and use hand control to manually point (slew) the telescope to three bright celestial objects. You do not need to know the names of the stars — you may even pick the moon or bright planets! Celestron’s NexStar® software technology will model the night sky to determine the position of every star, planet and celestial object above the horizon. Once aligned, the remote hand control allows direct access to each of the celestial catalogs in its user-friendly database.

Celestial Object Database

The CPC database contains over 40,000 celestial objects including Messier objects, the Caldwell Catalog, as well as NGC Galaxies, nebulae and planets. User-definable filter limits make navigating through this expansive database quicker and easier. Filter Limits let you filter out objects that are outside of your local horizon (ie, if trees or mountains were in the way).

Identify feature tells you what you’re looking at, but it can also be a very fun way to tour around the sky. Just point the telescope up somewhere and ask it to identify Messier objects (for instance) and it will show you the 5 nearest Messier objects to your position and let you GOTO them. You can keep doing this for different parts of the sky or for different object types — it is a lot of fun.

There’s also “Solar Sys Align” that lets you align on the sun or moon for daytime observing — it is easy to use this to see planets or bright stars in the day.

Innovative Features

The new CPC Series telescopes, like our acclaimed Advanced Series and premium CGE Series telescopes feature meticulously matched and hand-figured optical systems that are manufactured in our facilities in Torrance, California. In addition, all CPC models are available with StarBright and StarBright XLT High Performance Optical Coatings.

With the introduction of the CPC Series, Celestron has “gone back to the drawing board” and re-designed, re-engineered, and re-invented a telescope family that provides superior quality, unsurpassed ease of use, and incomparable value. All CPC models ship standard with our NexRemote telescope control software.

Astrophotography with the Celestron CPC Telescopes

While astrophotography could not be summed up here in one paragraph, a very common question for the CPC telescopes is how to connect a camera to it.  Astrophotography is a hobby of patience and lots of trial and error, and plenty of errors will be had once you get started.  But the rewards of good images is well worth it. 

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.

Schmidt-Cassegrain Advantages

• Very versatile, best all-purpose telescope design
• Combines the optical advantages of both lenses and mirrors while eliminating their disadvantages
• Excellent optics and razor sharp images over a wide field
• Excellent for deep sky observing and astrophotography as well as terrestrial viewing
• Very good for lunar, planetary and binary star observing
• Focal ratio generally around f/10, it also has the best near focus capability of any type of telescope
• Closed tube design reduces image-degrading air currents
• Extremely compact and portable
• Easy to use, durable and virtually maintenance free
• Large apertures at reasonable cost and less expensive than equivalent aperture refractors
• More accessories available than with other types of telescopes

Schmidt-Cassegrain Disadvantages

•  More expensive than Newtonians of equal aperture
• Slight light loss due to secondary mirror obstruction compared to refractors The Maksutov-Cassegrain is similar to the Schmidt-Cassegrain with essentially the same advantages and disadvantages. It uses a thick meniscus correcting lens with a strong curvature and a secondary mirror that is usually an aluminized spot on the corrector. The Maksutov secondary
