A telescope is an instrument that collects and focuses light. The nature of
the optical design determines how the light is focused. Some telescopes,

use mirrors. The EdgeHD optical system (Aplanatic Schmidt) uses a
combination of mirrors and lenses and is referred to as a compound or

Critical focusing is best accomplished when the focusing knob is turned

The image orientation changes depending on how the eyepiece is
inserted into the telescope. When using the star diagonal, the image is
right-side-up, but reversed from left-to-right (i.e., mirror image).

(i.e., inverted). This is normal for the Schmidt-Cassegrain design.
