What are Schmidt Cassegrain telescopes good 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.

How do you focus a Schmidt Cassegrain telescope?

The focusing knob, which moves the primary mirror, is on the rear cell of the telescope just below the star diagonal and eyepiece. Turn the focusing knob until the image is sharp. If the knob will not turn, it has reached the end of its travel on the focusing mechanism.

Are Schmidt Cassegrain telescopes good?

Small Maksutov-Cassegrain telescopes are a godsend for urban observers who need a compact scope with good optics. And “Maks” are back in style, so there’s a good selection on the market.

What can you see with an 8 inch Schmidt Cassegrain telescope?

4. Celestron NexStar Evolution 8 Schmidt Cassegrain Telescope. The NexStar 8 telescope also has a 200mm lens and offers spectacular views of the moon, planets, and deep sky objects.

Do Schmidt Cassegrain need collimation?

Precise collimation is essential to good performance for any Schmidt-Cassegrain telescope. For SCTs, it’s done by small adjustments to the tilt and position of the secondary mirror in its cell.

What type of telescope is a Schmidt Cassegrain?

catadioptric telescope
The Schmidt–Cassegrain is a catadioptric telescope that combines a Cassegrain reflector’s optical path with a Schmidt corrector plate to make a compact astronomical instrument that uses simple spherical surfaces.

What is a high power eyepiece?

A low-power wide-field eyepiece for taking in large celestial objects or framing multiple objects in the same field. A high-power eyepiece for seeing detail on planets and the Moon, for resolving double stars, and for observing small objects like planetary nebulae.
