Celestron C4.5 User Manual

G E T T IN G S T A R T E D
As with any optical instrument, there are several things you must know
about your C4.5 telescope to get the most out of it. This section deals with
basic information and initial use.
Image Orientation
The Newtonian optical system produces an inverted image (i.e., upside
down and backwards). Unfortunately, there is no accessory that reinverts
the images to match the orientation seen by the unaided human eye. How-
ever, this will only affect your terrestrial observations. For celestial viewing,
star charts can be made to match the view in the telescope simply by rotating
the chart 180° about the center. This orientation applies to the telescope’s
finder as well.

C4.5. Top is the actual orientation while below is an inverted image.
Both the C4.5 and its finder produce inverted images.
