Telescope image
All Reflecor telescope images are due
"cbreez" wrote in message ... Are all telescope images inverted ? Is there a way to change that like put on a eyepeice that corrects the image ? Inversion is an intergrate design due the optical charateristics. This applies only to reflective telescopes. Since reflector are used primarily for so-called deep space astronomy, this is not really a problem. On the other hand. a refractor which is normally used for terrestrial viewing gives an upright image. So if you are going to look for nebulae and distant galaxies the reflector is the way to go. The refractor is the telescope for terrestrial and local solar system objects. To answer your question, yes it is possible to purchase an "upright" lens for a reflector, but if you can find one of high quality it can prove to be prohibitively expensive.
