A Reflector telescope is a design that allows for large diameter objectives suitable for deep sky objects such as galaxies. Invented as an alternative to the refracting telescope in the 17th century by Sir Isaac Newton and known as the Newton telescope or the reflecting telescope.
Frequently Asked Questions
Which is better, a reflector or reflector telescope?
Refractor telescopes generally have the edge over reflector telescopes for image quality, both in respect of lens or mirror quality and precision optical mountings, and lack of central obscuration that is found in the reflector design.
Is a reflector telescope good for beginners?
The reflector telescope is a popular choice for beginners to astronomy – it offers the most aperture for your money of any optical design. The Celestron Astromaster 130EQ telescope uses a 130mm primary mirror and provides great light gathering power at a competitive price, making it ideal for beginners.
How does a reflector telescope work?
Light from space (in the direction you are viewing)is collected by the large mirror, forming the image. This large primary mirror, which can be quite wide, reflects the image to another smaller mirror. This smaller mirror reflects the light to an eyepiece lens, which then enlarges, and magnifies the image of the object you are viewing.
