Telescope manufacturers are not trying to trick you with all this. Which telescopes show an upside down view? Through an eyepiece, the sky will take on a different orientation depending on which scope you use. When you’re trying to star hop to a faint target under the muted glow of a red torch, reversed images can be trying.ĭo some experimenting to get an understanding of what’s best for you. The main reason for any adjustment is to make reading star charts easier. If you use more than one telescope when out observing and imaging, what do you need to do to make the orientation the same, so you don’t have to learn a completely different technique for locating objects? Credit: Pete Lawrenceĭespite the fact that you can argue, quite rightly, that there is no ‘up’ in space – what’s the right way up in the northern hemisphere appears upside down from the southern hemisphere, after all – it is still useful to know why some telescopes show things one way round and others show them differently, and how to ‘correct’ things for your comfort. Through a Cassegrain telescope, the Pleiades star cluster appears back to front. Our brains process these reversed images without a second thought, and a telescope is no different. It’s not like we don’t have to cope with such things in everyday life: take your reflection in the bathroom mirror, or the rear-view mirror of your car. Should I get a reflector or a refractorįor most, this is of no consequence whatsoever: you just get used to how any scope functions.Understanding the limits of your telescope.You just need to know that each telescope design has a different optical configuration, and that these different systems produce different views of the skies. Add some tilt into the view and you could be forgiven for thinking something was amiss.īut there’s nothing to worry about. Star patterns may appear mirrored left to right, upside-down, or even both at the same time. The first time you attempt this, may notice your telescope view is mirrored or upside down. Once you’ve bought a scope of your own, moving around the night sky becomes a more important consideration. Many amateur astronomers get their first proper look at the night sky through a telescope owned by a friend or relative. Why does my telescope show everything upside down?
