February, Telescope Image Orientation The truth of the matter, not all telescopes are the same, and not all show a flipped image, as this all depends on the type of telescope you use. Source: stargazingpro. When looking through the telescope, you might notice that the image is flipped upside down. Your first impression might be the telescope is broken - when in fact, it is working faultlessly.
Depending on the kind of telescope, images might appear correct, upside-down, rotated, or sometimes even inverted. Publisher Name. Tags: fixing image orientation image orientation inverted image Optics Trade optics trade blog telescope lens telescope mirror telsecopes.

Pentaprisms have worse light throughput than an Amici prism and are harder to manufacture, but produce sharper images. Ultimately, image orientation in a telescope is basically completely meaningless unless it has to do with aiming it at a particular target using a star chart.
The exception to this might be when trying to locate dim fuzzy objects in the field of view, but given that most large telescopes are Newtonian reflectors, rotating the chart degrees works as a solution.
The arguably more important reason to not bother with correcting the image, however, is that it hampers the overall quality of the view. An Amici prism diagonal will not only provide a slightly dimmer image than a regular star diagonal in a refractor or catadioptric, but it will vignette with low-power eyepieces and produces a bright spike, false color, and often glare on bright targets, which can seriously hamper viewing the Moon and planets — the few objects where you might be able to make the case for an upright image.
The amount of strain a long heavy prism with a likely heavy eyepiece on the far end puts on a focuser can also be an issue, as well as it throwing the balance of the whole telescope off.
This is really a matter of personal preference and geographic location. What looks right side up for someone in the United States will look upside down to someone in Australia, so you should probably focus on the overall aesthetic appeal of what orientation your image is displayed at.
