TELESCOPES ARE FANTASTIC
tools. They are opto-mechanical eye enhancements, enabling us to see extremely distant objects with increasing clarity. And the bigger a telescope’s aperture is, the farther and fainter the objects it can reveal. Amazing!
But one of the most surprising discoveries every amateur makes when they start exploring the night sky with their first telescope is that the image in the eyepiece differs noticeably from what might be expected — star patterns appear upside down or even mirrorreversed. So, what’s wrong?
Don’t worry, nothing is amiss. This is how telescopes work.
