Buying Guide for the Best Telescope For Iphones
When choosing a telescope that works well with iPhones, it's important to focus on how you'll be using the telescope—whether for casual skywatching, beginner astrophotography, or in-depth visual exploration. A good telescope for smartphone use should be easy to set up, stable for taking photos, and compatible with a wide range of phones. It's also worth considering what you want to see—planets, the Moon, deep-sky objects like galaxies, or a mix. Understanding the key features will help you find a telescope that's both enjoyable and practical for your needs.ApertureAperture refers to the diameter of the telescope's main lens or mirror, and it determines how much light the telescope can collect. A larger aperture allows you to see fainter objects and provides more detail, which is especially useful if you want to photograph celestial bodies with your iPhone. Apertures usually start around 60mm for beginner telescopes and go up from there. For casual viewing and basic photos of the Moon or planets, a small to medium aperture (60–90mm) works well. If you’re aiming to capture fainter, deep-sky objects, look for a larger aperture (100mm and up). Think about whether you want quick, easy stargazing or more detailed exploration to decide how much aperture you need.
Focal LengthFocal length is the distance between the telescope’s lens or mirror and the point where it brings the image to focus. It influences the magnification and the field of view you’ll get. Shorter focal lengths give a wider view—great for large star clusters or the Milky Way—while longer focal lengths help zoom in on planets and details, which are easier to photograph with a smartphone. Beginners often find medium focal lengths most versatile. If you plan mostly on planetary shots, lean toward longer focal lengths, but if you want broader sky photos, shorter focal length is key.
Mount TypeThe mount holds your telescope steady and lets you aim it at different parts of the sky. The two main types are alt-azimuth (which moves up/down and left/right, like a camera tripod) and equatorial (which tracks the sky’s motion). An alt-azimuth mount is simpler and works well for most beginners, especially for casual viewing and quick photo setups. Equatorial mounts are better for long exposure astrophotography but require more setup. For easy use with an iPhone, especially if you’re just starting out, an alt-azimuth mount is usually sufficient.
Smartphone Adapter CompatibilityNot all telescopes come with adapters for attaching smartphones. Some include basic adapters; others require you to buy an accessory. A good adapter holds your iPhone securely in line with the telescope’s eyepiece, making it easier to center objects and avoid shaky images. You’ll want to check that the adapter works with your phone’s size and camera placement. If taking photos is a priority, make sure the telescope comes with a sturdy adapter, or check that widely available adapters can fit the eyepiece size.
PortabilityPortability means how easy it is to carry and set up your telescope. Lighter, more compact telescopes are great if you want to travel or stargaze from different locations, while bigger telescopes may offer better performance but are heavier and less convenient to move. If you plan to use your telescope only in your backyard, size may be less important. If you’re interested in taking your gear to parks or remote locations for optimal night sky viewing and photography, look for a telescope designed for easy transport.
Eyepiece Quality and SelectionEyepieces determine the magnification and comfort of your viewing experience. Some telescopes include multiple eyepieces for different zoom levels. Higher-quality eyepieces provide clearer, sharper images, which is especially helpful for iPhone photography. Beginners benefit from a range of magnifications: one low-power (wide view) and one high-power (close up) eyepiece. Consider what you want to observe and photograph to decide whether a wide-range assortment or specific type of eyepiece is most useful.
