If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.
What is a disadvantage of a refractor telescope?
1. Very high initial cost relative to reflector. 2. A certain amount of secondary spectrum (chromatic aberration) unavoidable (reflector completely free of this)
Do astronomers use reflecting or refracting telescopes?
When you’re ready to invest in a stargazing telescope, start by looking at the different models of telescope tube – the bits with the optics in. You can find quite a few different designs. Reflecting telescopes use mirrors to gather the light. Refracting telescopes use lenses.
Which telescope has better magnification reflector or refractor?
If you compare a reflector telescope and refractor telescope of a similar size, the refractor telescope will generally have more magnification. This is because of the way the telescopes are set up internally, allowing for a longer focal length in a smaller refractor telescope.
What are refractor telescopes good for?
They are ideal for viewing larger, brighter objects such as the Moon and planets. Pluses for refractor telescopes include “right-side-up” images, the ability to come to thermal stability quickly meaning low image distortion, and a sealed tube which means little maintenance is required.
Can you see planets with a reflector telescope?
With a small telescope (2-inch or 60-mm refractor, 4-inch or 100-mm reflector), you can see some details on the surfaces of planets, but a larger telescope (3- to 4-inch or 75- to 100-mm refractor, 6- to 10-inch or 15- to 25-cm reflector) will reveal better detail.
Why are refractors better for planets?
The relatively small aperture of a refractor therefore often has an advantage over a larger reflector-type scope for this kind of observing, as there is less glare from a larger scope’s brightly lit planetary surfaces to wash out faint detail.
Why are refracting telescopes no longer used?
Limitations of Refracting Telescopes
Lenses create a type of image distortion known as chromatic aberration. This occurs because as light passes through a lens, different colors are bent through different angles (like in a prism) and brought to a focus at different points.

Can you see the Moon with a refractor telescope?
Using a telescope
One of the most useful ones is the “Sky & Telescope Field Map of the Moon,” available in both normal and mirror-reversed versions. The latter is mainly for observers with refractors and Cassegrain telescopes, which reverse the moon’s image left to right.
Is a 4 inch refractor good?
In general, a top-quality 4-inch refractor shows deep-sky objects about as well as a 5-inch reflector or catadioptric, and might even do a bit better on the planets. Most telescopes with apertures of 80 mm or less are refractors.
How do I choose a refracting telescope?
The main specification you want to consider when choosing a telescope is its aperture—the diameter of its main mirror or lens. The larger the diameter, the more light the telescope collects, allowing you to see fainter objects and more detail on nearby, bright objects like the Moon.
What size telescope do I need to see the rings of Saturn?
The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times]. A good 3-inch scope at 50x [magnified by 50 times] can show them as a separate structure detached on all sides from the ball of the planet.
