Buying Guide for the Best Beginners Telescopes
Choosing your first telescope is an exciting step into the world of astronomy. As a beginner, your goal should be to find a telescope that is easy to use, reliable, and offers good views without overwhelming complexity. Focusing on the right features will ensure you have a great experience exploring the night sky and learning as you go.Aperture SizeAperture is the diameter of the main lens or mirror that gathers light. It’s the most important factor because it determines how much detail you can see and how bright objects appear. Aperture is measured in millimeters or inches. Small apertures (up to 70mm or 2.8 inches) are very portable and great for easy viewing of the moon and bright planets. Medium apertures (70–114mm or 2.8–4.5 inches) offer a good balance for seeing more details on planets and some deep space objects. Large apertures (above 114mm or 4.5 inches) pull in more light for faint objects but can be heavy and less portable. As a beginner, choose a size that you can easily handle and store, but big enough for you to enjoy the views you’re most interested in.
Mount TypeThe mount is what holds the telescope steady and lets you point it at the night sky. There are two common types: alt-azimuth and equatorial. Alt-azimuth mounts move up/down and left/right, just like a camera tripod, and are the simplest to learn and use—perfect for beginners who want stress-free setup. Equatorial mounts are designed to follow the rotation of the sky for longer tracking of stars but require a bit more setup and understanding. Beginners often benefit most from the straightforward alt-azimuth or 'dobsonian' style mount for relaxed, easy stargazing.
Focal LengthFocal length is the distance the light travels inside the telescope from the lens or mirror to the eyepiece, measured in millimeters. This affects the telescope’s magnification, with longer focal lengths producing higher magnification. Short focal lengths (under 700mm) give wide views of star fields and big sky objects, while longer focal lengths (over 1000mm) are better for detailed views of the moon and planets. Think about what interests you: for viewing planets, a longer focal length may help, but for sweeping sky views and learning constellations, a shorter focal length can be more enjoyable.
PortabilityPortability is about how easy it is to carry, set up, and store your telescope. Smaller and lighter telescopes are great for carrying to a park or transporting in a car, while larger scopes might offer brighter images but can be bulky and harder to move. If you don’t have a dedicated space at home, consider a telescope that’s easy to pack away or move around so using it doesn’t feel like a chore.
Ease of UseEase of use covers how intuitive the telescope is from setup to operation. Beginners should look for telescopes that require minimal assembly and simple controls. Features like tool-free assembly, simple finder scopes, and straightforward adjustment knobs make your early experiences much more enjoyable. A telescope that’s too complex may gather dust, while a user-friendly one encourages you to get outside and use it often.
