![]() Right ascension is similar to longitude moving in an east or west direction and measured in hours from 0h to 23h. This eliminates field rotation and additional adjustment.Įquatorial mounts navigate celestial targets using right ascension (R.A.) and declination (Dec.). They do so by keeping the polar axis in alignment with the Earth's axis. The two main categories of astronomical telescope mounts are Equatorial and Alt-Azimuth mounts.Įquatorial mounts take into consideration the Earth's rotation axis. Allowing for proper maneuvering of the telescope's positionĪlternatively, a cheap wobbly mount will reduce your ability for an optimal viewing experience. ![]() The right telescope mount can optimize your observing experience as you look across the night sky by: With artificial intelligence (AI) and advanced camera sensors, smart telescopes are able to hone in on various objects in the night sky, from the touch of a button.Īs light pollution gets increasingly worse, especially in urban settings, smart telescopes have drastically increased the ability for both newcomers and veterans to continue enjoying unparalleled crisp and detailed views of the universe. Smart telescopes, or digital telescopes, are another telescope type that has revolutionized astronomy. Additionally, they can be heavier to carry and larger in size. It is important to note that catadioptric telescopes tend to be on the more expensive side due to the complexity of design. By using both reflection and refraction, catadioptric telescopes are more error-corrective than a reflector or refractor alone. Many of the most famous telescopes used for astronomical research are reflectors, such as the Hubble Space Telescope.Ĭatadioptric telescopes combine specifically curved mirrors and lenses to form an image. Since the manufacturing of large mirrors is cheaper than large lenses, reflectors are often times less expensive to purchase than refractors. It is then reflected to a secondary mirror (or more) before arriving at the eyepiece or camera. Light enters the telescope through the front and bounces off a curved mirror at the rear. Reflector telescopes, or reflectors, use a single or an arrangement of curved mirrors that reflect light to form an image. In comparison to the other telescope types, refractors tend to be the most portable.
