A catadioptric telescope, or compound telescope, is a type of telescope that combines the principles of both reflection and refraction by using mirrors and lenses. Knowing how the mirrors and lenses work together is crucial to taking advantage of the full potential of catadioptric telescopes. A catadioptric telescope captures and focuses light from distant objects…
The Maksutov-Cassegrain (Mak) telescope is a type of catadioptric telescope that employs both mirrors and lenses to produce an image. Its design incorporates a thick meniscus corrector lens and a spherical primary mirror, efficiently reducing optical aberrations. The Maksutov is recognized for delivering high contrast, particularly in planetary observation, and has become a preferred choice…
The Cassegrain reflector is a type of telescope that uses a combination of a concave primary mirror and a convex secondary mirror to gather and refocus light, producing magnified images of distant celestial objects. Knowing the interplay between these mirrors is vital to optimizing observations with the Cassegrain design. The Cassegrain telescope’s ability to provide…
The Schmidt-Cassegrain Telescope (SCT) is a compound telescope that combines mirrors and lenses to create an image. The SCT uses a spherical primary mirror, a secondary mirror, and a corrector plate to correct spherical aberration, resulting in a compact and adaptable instrument. The SCT is known for its portability and versatility among both amateur astronomers…
A Newtonian telescope, invented by Sir Isaac Newton, is a type of reflecting telescope. Newtonian telescope uses a concave primary mirror and a flat secondary mirror to gather and focus light from distant celestial objects. Newtonian telescope is known for its simple and efficient design, making it popular among amateur astronomers. It provides wide field…
Dobsonian telescopes are modified Newtonian reflector telescopes popularized by John Dobson in 1965. Amateur astronomers prefer Dobsonian telescopes for their large aperture, low cost, and portability. Dobsonian telescopes use a concave mirror as the objective lens to collect and focus light from distant objects. Dobsonian telescopes are available in sizes ranging from small portable models…
A reflecting telescope works by using mirrors to gather and focus light from the cosmos, providing detailed images of distant celestial objects. The primary mirror, which is concave in shape, captures the light, which is then focused onto a smaller area. A secondary mirror, positioned at a 45-degree angle, redirects the focused light towards the…
