What are the basic parts of a Schmidt Cassegrain telescope?
The Schmidt-Cassegrain system consists of a zero power corrector plate, a spherical primary mirror, and a secondary mirror. Once light rays enter the optical system, they travel the length of the optical tube three times.
What are Schmidt-Cassegrain telescopes best for?
They are also well-suited to a number of applications including photography and terrestrial observing as well as stargazing. Most new SCTs are computerized, adding to their ease of use and portability. Schmidt-Cassegrain telescopes are a catadioptric design, meaning they use both lenses and mirrors.
Are Schmidt-Cassegrain telescopes good?
Schmidt Cassegrain telescopes are powerful, compact instruments with loads of utility. Good products will have you seeing stars, while subpar units will only frustrate. To separate the good from the bad, we’ve tested many dozens of different options.
Why can’t I see through my Celestron telescope?
If you can’t see anything clearly through your telescope using your eyepiece, try using a different eyepiece; switch from a high-power eyepiece to a lower-power (ex: 4mm to a 20mm eyepiece) instead. Always start with the lowest power eyepiece (the one with the highest number in millimeters printed on it).
What is the difference between a Cassegrain and a Schmidt Cassegrain telescope?
The main difference between Schmidt-Cassegrains and Maksutov-Cassegrains is the corrector lens at the front of the telescope. Both scopes use spherical mirrors which induce spherical aberration.
Why can’t I see the moon through my telescope?
If you are unable to find objects while using your telescope, you will need to make sure the finderscope is aligned with the telescope. The finderscope is the small scope attached near the rear of the telescope just above the eyepiece holder. This is best done when the scope is first set up.
Why can’ti see planets through my telescope?
Planets are small and far enough away that they will never fill a significant portion of your field-of-view, even at you scope’s highest usable magnification. If you want to see a larger disk, you need to use a higher power eyepiece.
