![]() ![]() Though their native focal length is very long, a variety of focal reducers made for SCTs can allow them to be used at medium and ultra-short focal lengths, which transform them into excellent performers for deep sky astrophotography. SCTs are also arguably the most versatile telescope for sale today. Many beginner SCTs come packaged with a motorized go-to mount that can automatically point and track objects after a simple alignment process, which is basically a requirement to make sure you don't get lost in space looking for an object. The long focal length is a double-edged sword, though, as it can make locating objects in the night sky like trying to look at space through a straw. Offering some of the longest focal lengths available in telescopes, SCTs are a fantastic choice for those looking to view - and especially to image - solar system objects like planets and the moon. Schmidt-Cassegrain Telescopes (SCTs) are wildly popular telescopes for sale among both beginner and advanced amateurs thanks to their versatility. That said, refractors are some of the easiest and most versatile telescopes to use, and we highly recommend them especially for those looking to begin deep sky astrophotography. ![]() Because of the great things they have going for them, quality refractors like apochromatic triplets and doublets are some of the most expensive telescopes for sale, per inch of aperture, or diameter of the telescope.įor that reason, a Dobsonian telescope will usually outperform a refractor of the same price range visually, and a Schmidt-Cassegrain will outperform a refractor of the same price range for planetary viewing and imaging. This designation is reserved for high-quality refractors that are free from false color or chromatic aberration. One of the terms you’ll come across when reading about refractors is APO, or apochromatic. Refractors are excellent for their portability, ease-of-use, and familiarity - refractors are very similar to camera lenses, which is a big plus for budding astrophotographers. They’re also great for terrestrial viewing of landscapes, birds, whales, etc. Here at All Star Telescope we love Refracting telescopes. If you’re interested in astrophotography, particularly deep sky astrophotography, refractors are the best beginner telescope. Galileo invented this style of telescope and used it to discover the moons of Jupiter, the Rings of Saturn, and to develop his heliocentric model of the solar system. Refractors are what you imagine when you think of a telescope. ![]()
