A smaller field of view will allow you to see more details on the celestial bodies you observe. You can view a larger field by using low magnifications and high magnification for a smaller field of view. The size of a field of view for a telescope depends on the magnification. You can adjust the field of view of a reflector telescope by changing eyepieces. You can find modification eyepieces for your telescope online. Additionally, you can swap the eyepieces with ease when observing celestial bodies under different magnifications. You can upgrade your eyepieces to magnify 200x to 500x to get a more detailed view of the sky. You will get two or more eyepieces after purchase, which will be handy when learning how to use a telescope. Moreover, you can move the telescope with ease to and from your favorite observation location.Ī user can upgrade the magnification capacity of a telescope because magnification power is part of the eyepiece. Overall, a lightweight telescope gives the option to pick a suitable location to do observations depending on where they live.įor example, you can move to a location where there are no buildings to obscure your view of the sky anywhere in the city. You can carry your telescope for various outdoor activities and watch the sky from different perspectives. Therefore, beginners don’t have to spend a fortune to get an effective telescope for observing the sky.Ī lightweight telescope is simple to set up outdoors and when traveling to new locations. They use a basic design that Isaac Newton developed in the 1660s, with a few modern modifications. Reflector telescopes are affordable because they use ordinary materials and they are simple to produce. Overall, a reflector telescope is an excellent choice for beginners. You can explore the sky and learn about celestial bodies. Moreover, it allows in a lot of light that allows the viewer to see celestial bodies well. The telescope has a simple design that newbies can adjust when looking at the sky. Beginners can learn about various celestial bodies as they start doing astronomy or astrophotography as a hobby. ProsĪ reflector telescope is excellent for beginners because it shows a wide field of view. There are many advantages to using a reflector telescope for astronomy and hobby sky gazing. The reflector telescope is the most popular because they are excellent for sky gazing and hobby astronomy. The telescope is placed at the front, which is a defining characteristic of a reflector telescope. It has a large primary mirror reflecting light from the back of the telescope to a series of small mirrors. Conclusion What is a Reflector Telescope?Ī reflector telescope uses a series of mirrors to reflect an image. Equally important in a choice of telescope type is the focal length and the resulting field of view. Refractors generally have the edge over reflectors for a quality image, both from the standpoint of lens/mirror quality and precision optical mountings, and lack of central obscurations. Refractors don't suffer from this problem. While not aesthetically objectionable, it is true that any obstructions can degrade the image a little. Reflecting telescopes, with their secondary mirror (generally with mirror supports), often produce "diffraction spikes" around star images.However, the brightness of a nebula is proportional to D2/FL2 since the image of the nebula is also spread out over x and y dimensions by an amount proportional to the focal length (FL). For photographs of nebulae and galaxies, the focal ratio of the telescope is very important! The brightness of stars (point sources) is proportional to D2 (the Diameter of the telescope, and D2 is proportional to the collecting area, pi*R2).Plate scale (in arcseconds/mm) and the amount of the sky shown on your image depends only on the focal length of the telescope. Are you interested in a moderately wide field, say enough to capture the Orion nebula? Then a short focal length telescope (and correspondingly smaller plate scale) will get more of the sky onto film of a given size.Are you interested in photographing a very faint object? Perhaps a faint Cepheid variable star? A large reflector will collect a lot more light, and the resulting small field of view is not a problem.Is a reflector better for astrophotography? Or a refractor? Well.
