A reflector type telescope always inverts the image, unless of course you are using it for star gazing, then it doesn't matter. However, if you are using it to view a planet you must remember you are looking at the object upside down, unless of course you have a correcting prism installed in your eye piece holder.
Newton built the first reflector telescope.
They both use a parabolic reflector.
A reflector or reflecting telescope.
The lenses used in reflector telescope is the concave lens.
The Hubble telescope is a so-called Cassegrain reflector, which means it uses mirrors, two to be exact. A large one (primary reflector) for collecting the light, the smaller one (secondary reflector) for directing the light from the primary reflector to the observation opening. Therefore, the Hubble telescope does not make use of a lens.
Most telescopes use refractor lenses. Sometime a telescope will use reflector lenses.
it is a reflector telescope
A Cassegrain reflector
A Reflector or Reflecting telescope.
The Newtonian Telescope.
The HST does not use a lens but a mirror. It is a so-called Cassegrain reflector.
a refractor or a reflector are two types of telescope.
The HST is a Cassegrain reflector telescope.
Amazon has Reflector telescopes for about $260. Customer reviews for this telescope is high. Most of the reviews claim this telescope is absolutely amazing.
Even though other scientists like Galileo had the idea for a reflecting telescope, Sir Isaac Newton is credited with perfecting the reflector telescope in 1668.
The Newtonian Reflector.
It's a telescope,that uses reflectors for you to see the objective ;D.
If you are not used to telescopes you will find a refractor easier to use than a reflector.
The classical Galileo telescope was a refractor telescope, i.e. a telescope using lenses instead of mirrors.
No, it isn't. The Hubble Space Telescope is a reflector. It has a primary mirror, and not a primary lens.
