Newtonian reflector:
After light hits the main mirror, proceeds back up the tube and hits a secondary mirror
suspended in the middle of the tube, the secondary mirror directs it to the side, where
it exits through a hole in the side of the tube. The camera or eyepiece is mounted on
the side.
Cassegrain reflector:
After light hits the main mirror, proceeds back up the tube and hits a secondary mirror
suspended in the middle of the tube, the secondary mirror directs it back down to the
bottom of the tube again, where it exits through a hole in the center of the main mirror.
The camera or eyepiece is mounted at the bottom of the tube, making it look just like a
refracting telescope.

What was the Newtonian achievement?
The Newtonian achievement is the Newtonian telescope. It is a kind of reflecting telescope that was created during the seventeenth century by Isaac Newton
What are the main reflectors of solar energy?
Clouds are the main reflectors of solar energy.
Why is concave mirror useful as solar reflectors?
If the mirror converges, the light produced will be strong. This means they will be useful as solar reflectors.
Who invented parabolic reflectors?
Ibn Al Haytham
What is one characteristic of galaxies that requires the use of general relativity instead of newtonian theory?
What is one characteristic of galaxies that requires the use of General Relativity instead of Newtonian theory?
What type of telescope concave mirrors to gather light and view the image?
Reflecting telescope. Most useful reflectors are compound types, combining a system of mirrors and lenses, such as the Newtonian and Cassegrain.
What type telescopes use mirrors to bring light to focus.?
Reflectors - the main two types being Newtonian and Cassegrainian.
What does the reflecting telscope do?
They use a mirror instead of a lens to focus light into the eyepiece. Newtonian telescopes are the most common type. Schmidt-Cassegrain is also a popular design but more complex and expensive.
When did Laurent Cassegrain die?
Laurent Cassegrain died in 1638.
When was Laurent Cassegrain born?
Laurent Cassegrain was born in 1629.
What has the author Arthur Cassegrain written?
Arthur Cassegrain has written: 'La grand-tronciade'
How did the refracting telescope add your understanding of the earth?
There are many types of telescopes you can use. Refracting telescope which receives light directly throughout a series of lenses. Newtonian Reflecting is another which receives light from a primary mirror and reflects it to a secondary mirror which sends the light to the eye piece. Newtonian Reflectors are my favorite.
Is benzene a newtonian fluid or non-Newtonian fluid?
Newtonian
Is glycerol a newtonian or non newtonian fluid?
Yes, newtonian fluid.
What is a design of astronomical reflecting telescope?
Cassegrain
Is guar gum a newtonian or non newtonian fluids?
No, gum is not a non newtonian
What are the different types of fluid?
All fluid in the human body is basically interstitial fluid. When it is in different parts of the body it is given different names: lymph, serum, synovial fluid, cerebrospinal fluid, plasma, etc.
