Refractors or reflectors: which is the superior telescope?
- A 4 inch (100mm) reflector would be an excellent starting point for beginning amateur astronomers. Refractor Telescopes are optical instruments with lenses that are often long and slender in appearance. They are particularly well suited for observing bigger, brighter objects such as the Moon and the planets.

When should you use a refractor telescope?
Telescopes with a refractive element are simple to operate and maintain, and they are excellent for high-contrast viewing and imaging of double stars, planets, and deep-sky objects. Specifications: The two most important parameters to consider when making a purchase decision are the aperture and magnification.
How do you use a telescope for the first time?
Using your hands, manually orient the telescope as accurately as you can at the target, and then gaze through it. When you look through the telescope, you should be able to see the target in the center of the eyepiece. If it isn’t, use the slow motion control knob or dial on the telescope’s mount to make changes until it is.
How does a refracting telescope work step by step?
Refracting telescopes function by focusing light via two lenses, giving the impression that the item is closer to you than it actually is. Both lenses have a form that is referred to as a ‘convex’ shape. In order for convex lenses to function, light must be bent inwards (like in the diagram). This is what gives the impression that the image is smaller.
What is a good aperture for a refractor telescope?
The following are the most important parameters for a truly functional first telescope: a minimum aperture of at least 90mm for a refractor and 130mm for a reflector, as well as a focal length of at least 1,000mm for each. This combination will offer sufficient light grab while also allowing for a high enough magnification to discern fine detail on the brighter planets in the solar system.
What can I see with 80 mm refractor?
Large deep-sky objects may be captured with ease because to the 80mm objective lens and short 400mm (f/5.0) focal length, which makes it an excellent choice for wide-field photography. With this telescope, you’ll be able to see stunning star clusters, wispy nebulae, and huge galaxies, but it also performs well when observing things inside our own solar system.
Why can’t I see anything in my telescope?
If you are having difficulty locating things via your telescope, check that the finderscope is properly aligned with the telescope. This little scope is mounted to the rear of the telescope, right above the eyepiece holder, and is known as the finderscope. This is best accomplished during the initial setup of the scope.
What are 2 problems with refracting telescopes?
Chromatic aberration and spherical aberration are the two main issues that refracting telescopes have to deal with.
How does a refractor telescope create an image?
A basic refracting telescope is comprised of two lenses: the objective and the eyepiece, both of which are made of glass. Essentially, the objective lens creates a picture of a distant object at its focus, and the eyepiece lens amplifies this image to make it more visible.
Can you damage your eyes looking at the Moon through a telescope?
Yes, it is correct. When compared to the intensity of the sun’s light, the light reflected off the moon’s surface has a very low degree of intensity. Consequently, staring at a full moon has no risk of causing damage to your eyesight. If you look through a moderately powered telescope at the full moon, the brightness of the moon will almost likely cause your eyes to become dizzy.
