Some telescope models are designed to mount easily to DSLRs for astrophotography, while others come in kits with telescope accessories like tripods, filters, eyepieces, and more. Other Features to ConsiderĬomputerized telescopes make it much easier to locate and track celestial objects utilizing preprogrammed databases. Smaller aperture telescopes also show celestial objects in lower resolution than larger aperture telescopes. While small aperture telescopes are more physically compact and less expensive, they will only allow you to see the brightest space objects. Small apertures (1.2” or 2.5”) will let in significantly less light than larger apertures (12” or 14”). Aperture SizeĪpertures are very important when selecting a model because they will affect how much light is collected by the telescope. You can easily filter search results by type to select the varieties most suited to your needs. There is also the Cassegrain variety, which utilizes multiple curved mirrors to view deep space objects while maintaining a smaller physical profile. In most cases reflecting telescopes are less expensive than refracting telescopes because mirrors cost far less to produce than lenses, especially for larger format telescopes. Reflecting telescopes are generally less expensive and don’t have issues with chromatic aberration. Refracting telescopes are often preferable because they are sealed to air and dust and require less maintenance, though they often suffer from chromatic aberration. Refracting telescopes utilize lenses in a similar way to binoculars to bring distant objects into view, while reflecting telescopes utilize mirrors. The two most common types of telescopes are refracting telescopes and reflecting telescopes. What are the Different Types of Telescopes?
