On the other hand, higher-end triplet refractors can provide some of the best views and images of any telescope type and are an excellent choice for astrophotography imagers of all skill levels.
However, most entry-level doublet refractors won’t provide as good of a view as a similarly-priced reflector or catadioptric because of their smaller aperture. Image 1 Agena Astro tested the 8-inch classical Cassegrain telescope before repackaging it in this doubled layer cardboard box with ample Styrofoam. Cassegrains were lighter and easier to mount on clock drives. They also require the least amount of maintenance, which is a huge plus. Secondly, the mirror design provided long focal lengths without the need for long optical tube assemblies. Refractors are great for those on a budget as they are the least expensive type of beginner telescope.
Using glass lenses, refracting telescopes magnify incoming light down a long, narrow tube. Refractors are what most people picture when they imagine a telescope.
