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

    Comments about Celestron C6-A Schmidt-Cassegrain Optical Tube Assembly:

    I have had this scope now for about three or four months, and I have to say that I love it. The image quality is fantastic, particularly from a dark sky site. Globular clusters are particularly impressive, as are galaxies, nebulae, planets and the moon. Pretty much anything you would care to look at.

    Truthfully, there are limits to a 6" scope as compared to bigger and more expensive ones. This past weekend I had my 6" out next to a friend's 12" Schmidt-Cassegrain. Naturally the 12" had brighter and clearer images, but I don't know if they were thousands of dollars brighter and clearer. So this definitely has a lot of bang for the buck. It probably cost about 1/6 of what that 12" cost, yet the image quality was approaching that of what you got with the 12".

    Another advantage this scope has is size. I bought a hard case for it, putting the factory foam shipping insert into the case. In this configuration, it's just about the right size to be able to take on an airplane as carry-on luggage, which I have done. I don't know that you can find another 6" scope that can travel so easily. Newtonians and Dobsonians are too big to take aboard a plane and have to be checked in, which is a scary thought.

    This scope took a little bit of tweaking to make it work optimally. First of all, the collimation may need to be adjusted. This is incredibly easy with this scope, it only requires looking through the scope while turning a screwdriver. The other thing was that, from the factory, the this scope came with what looked like an uneven oily film on the corrector plate. I was hesitant to clean it because I know it's a coated corrector plate and they tend to be very touchy. Finally someone convinced me that the oily film was likely some type of substance used to adhere the corrector plate to the tube, and some of it had seeped out onto the plate. Using a very soft cloth and 91% alcohol, I was able to remove this film. Afterwards, the image quality went from good to outstanding.

    Comments about Celestron C6-A Schmidt-Cassegrain Optical Tube Assembly:

    Well built and nice looking scope. The views are great,very sharp for a Schmidt Cass. The only drawbacks would be the undersized finderscope, and the diagonal which should be replaced with a high quality one.
