In general, refractors most suited to planetary and moon viewing by amateur astronomers. This makes the refractor telescope impractical to use for serious research. The larger the telescope, the more obvious these problems become. Refractors generally have the edge over reflectors for a quality image, both from the standpoint of lens/mirror quality and precision optical mountings, and. A refractor telescope has difficulty taking in certain kinds of light, particularly ultraviolet light, which is unable to pass through the objective. They are subject to a number of light anomalies, the most problematic of which is chromatic aberration, a distortion that causes a rainbow of light around viewed objects. Refractors do have disadvantages, particularly for those with a more advanced knowledge of astronomy. A refractor telescope uses a large convex lens at the end and refracts light into a smaller image to the telescopes back. A refractor telescope has a closed tube, which means it can not accumulate dirt and dust on the inside, and therefore does not require internal cleaning.
It is typically shorter and smaller than the reflector, which makes it easier to carry around. Which is better A refractor telescope is better because it has a broader field of view. That’s really the biggest difference between the two telescopes. A reflecting telescope is open at one end, meaning that the objective can get dirty and must be cleaned regularly, a process that can be dangerous to the expensive mirrors if not performed properly. Reflector telescopes are made up of mirrors, while refractor telescopes have lenses. Refractors require no calibration by the user at all. Reflectors need to be "collimated," or realigned, with just about every use, and sometimes even during use as temperatures change. The main difference is the reflector uses a concave mirror as the primary optical device, whereas the refractor. The optics are less likely to shift than the mirrors on a reflector, an occurrence that causes misalignment and blurring of objects. The basic similarities between these two are that, they are both being used as astronomical devices both designs use a lens as the eyepiece, and calculations such as Magnification, F-Number and Resolution are same for both models. There are some characteristics of refractor telescope that makes them more appealing than reflectors for those who are new to star gazing.
