- Port for Smartphone Camera: Includes a special adapter (mount) that stabilizes the phone over the eyepiece. This aligns the phone’s camera with the telescope, making it easy to photograph the Moon and planets.
- Robotic (GoTo): It features a built-in computer and electric motors that allow it to perform functions automatically, without you needing to move it by hand.
- Smart: It does not have an eyepiece and is controlled via a mobile app. It finds stars on its own, photographs them, and shows colorful galaxies and nebulae on the screen.
- Wi-Fi: They have the ability for wireless communication of the device with smart devices (mobile phones, tablets, PCs) for its control.
- Reflecting: They use a mirror to gather light. Then, with a secondary mirror at a 45-degree angle, they direct the light to the eyepiece.
- Dioptric: They use a lens that refracts light and focuses it onto a second lens called the eyepiece, which acts as a magnifier.
- Catadioptric: They use lenses and mirrors. Light passes through a lens at the front which prepares it, and then, with the help of successive mirrors, the light reaches the eyepiece lens.
- 30-50mm: Refers to small telescopes, suitable for beginners or for observing bright objects such as the Moon and planets.
- 51-70mm: Refers to medium telescopes for more detailed observation of planets and bright nebulae.
- 71-90mm: Refers to telescopes with greater light-gathering capability, ideal for astronomy enthusiasts and observing fainter celestial objects.
- 91-130mm: Refers to powerful telescopes for impressive observation of nebulae, constellations, and details on planets and the Moon.
- Over 130mm: Refers to advanced telescopes, suitable for serious amateur astronomers who want to observe faint objects and galaxies.
- Star Clusters & Large Nebulae: (Focal Length Range up to 700mm) Offers a wide field of view, ideal for observing large areas of the sky, such as nebulae and star clusters.
- Planets & Deep Sky Objects: (Focal Length Range 700-1300mm) Provides good magnification without losing much of the field of view. Suitable for medium-sized objects, e.g. individual star systems or planets with a relatively large surface area.
- Planetary Nebulae & Globular Clusters: (Focal Length Range over 1300mm) Provides high magnification with a narrower field of view, ideal for detailed observation of planets, lunar craters, or small objects such as distant galaxies.
- Beginner: It refers to telescopes with an objective lens diameter smaller than 80 mm. These telescopes are usually compact, portable, and ideal for a beginner user.
- Familiar: Refers to telescopes with an objective lens diameter from 80mm to 185mm. These telescopes require more familiarity and are not suitable for a beginner user, but on the other hand, they are not sufficient to meet the needs of an experienced user.
- Experienced: Refers to telescopes with an objective lens diameter greater than 185 mm. These telescopes are usually bulky, heavy, and difficult to set up and align, so they are unsuitable for someone without advanced experience.
- Altazimuth: The simplest option. It moves like our head, up-down and left-right. It is ideal for quick tours of the stars or nature, as it is easy and intuitive to use, just like a classic camera tripod.
- Equator: Designed to "lock onto" stars, following their curved path across the sky. Although it requires a small adjustment at first, it allows you to track a star along an imaginary arc, moving only one lever without ever losing it.
