Yes, telescopes can produce both real and virtual images. The type of image produced by a telescope depends on the type of telescope and the configuration of its optical components.Refracting telescopes, which use lenses, typically produce real images because the final image is formed by the convergence of actual light rays at the focal plane….
Yes, most of modern telescope eyepieces are universal, however older eyepieces are not universally interchangeable. The interchangeability of telescope eyepieces depends on the telescope’s design and the focal length of the eyepiece. Telescopes that use a 1.25-inch or 2-inch diameter barrel system can accept eyepieces of those sizes. However, some telescopes, particularly older or entry-level…
For planet viewing, refractor telescopes are the best telescopes for beginners because they have excellent contrast and resolution for viewing the Moon and planets up close. They are also the easiest telescope type to use and require the least maintenance. However, for more advanced planet viewing, especially if you are interested in astrophotography, you will…
