It is ideal for star fields, star clusters, galaxies, planets, nebulae, the Moon, and (with the right filtering or by projection) the Sun. The Sky-Watcher StarTravel 120 AZ3 f/5 Doublet Refracting Telescope is the best budget refractor telescope on this list. Sky-Watcher StarTravel 120 AZ3 f/5 Doublet Refracting Telescope Note that the flattener is sold separately, so if you want to use this telescope to take photos, you’ll need to purchase it. It may be the best apochromatic refractor telescope for beginner and intermediate astrophotographers. The Sky-Watcher EvoStar 80 ED APO Refractor Telescope is a dependable, modestly-priced apochromatic workhorse that’s great for eyepiece viewing and astrophotography alike. Sky-Watcher EvoStar 80 ED APO Refractor Telescope With an edge-to-edge self-flattening field design and quadruplet Petzval optics, this could well be the.īe aware that this refractor is fairly heavy at 27.56 lbs, and you’ll need a solid (and expensive) mount to handle the weight for astrophotography. Though it is pricier than the Radian 75mm, the Askar 130PHQ APO Quadruplet Astrograph delivers yet more capabilities for the avid astrophotographer. It eliminates issues associated with back focus by preventing any moving elements in the system, a novel concept that dramatically simplifies the process of setting up to observe. With FCD 100 glass and an easy setup, the Radian 75MM Petzval Refractor Telescope is the perfect refractor if you’re interested in deep-sky astrophotography. Without further ado, we present our picks for the top nine best refractor telescopes: 1. Also, check the accessories that come with the telescope, such as eyepieces, finder scopes, and diagonals, as these accessories can greatly enhance the user experience. ![]() Look for telescopes that are made with durable and high-quality materials, as they will last longer and provide better performance. Lastly, consider the overall design and build quality of the telescope. Equatorial mounts are generally recommended for more advanced users. A refractor telescope can be mounted on an Alt-Azimuth or an Equatorial mount an Alt-Azimuth mount is easier to set up, but an equatorial mount allows for easier tracking of objects in the night sky. Multi-coating also helps protect against smearing and other related problems.ĭecide which type of mount you want to use for your observations. Look for telescopes that use high-quality, multi-coated lenses, as they will produce brighter and clearer images. Refractor telescopes use lenses instead of mirrors to gather and focus light, and the quality of these lenses can greatly affect the overall image quality. A good rule of thumb is to have a focal length of at least 500mm for general-purpose observation.Īnother important factor to consider is the quality of the optics. ![]() A telescope with a longer focal length will provide a higher magnification, but a shorter focal length will give you a wider field of view. ![]() The focal length is the distance from the objective lens to the point where the image is focused. Next, consider the focal length of the telescope. Aperture sizes for refractor telescopes typically range from 50mm to 150mm. This is the diameter of the objective lens, or the main lens that gathers light - the larger the aperture, the more light the telescope can gather, resulting in brighter and clearer images. There are five main considerations for purchasing a refractor telescope. What to Look for in a Refractor Telescope OPT carries a wide range of refractor telescopes from brands such as Celestron, Explore Scientific, Sky-Watcher, and others, and we are here to help guide you toward the best refractor telescope for your needs. There are many different types and models available, each with its unique features and specifications. Shopping for a refractor telescope can be a daunting task, especially for beginners.
