Which is better Newtonian or Cassegrain telescope?

For equivalent size telescopes in aperture cassegrains are more compact than newtonians so a larger aperture may be easier to handle. Both types of telescopes can be used for photography but I think cassegrains may have a few more accessories that make them a little better suited for photography.

Do Schmidt Cassegrain telescopes 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.

How much is a Schmidt Cassegrain telescope?

Although you won’t see many SCTs under the $500 mark, you can find many under $1000, including the highly-regarded Celestron Nexstar SE series.

How do you collimate a Schmidt Cassegrain telescope?

To collimate the SCT or EdgeHD, follow these steps:

1. Center the bright star in the eyepiece’s field of view.
2. Defocus the star until you can see a dark “hole” in the center (i.e. the shadow of the secondary mirror) and 2-4 diffraction rings of light around it.
3. Inspect the out-of-focus (“extra-focal”) diffraction pattern.

What type of telescope is the 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.

How a Schmidt-Cassegrain telescope works?

Schmidt-Cassegrain telescopes are a catadioptric design, meaning they use both lenses and mirrors. It is reflected from a concave primary mirror at the back of the scope which focuses the light to the front of the telescope where it is reflected again by a smaller, convex secondary mirror.
