Telescope Viewing Image Upside Down?

[Joey Bee]

Hi, I have just recently bought a Hokenn scope and need some advice with regards to the image.

I've set it up on a level surface with the tripod legs fully extended but when I look through the scope at a terrestrial image the image is rotated by about 20 degrees!

Can this be adjusted in any way or is it a fault with the scope.

Many thanks,

Reflectors aren't used for terrestrial viewing, that is why image is upside down, rotated or reversed, not sure which of these you would explain it with.

Hope you get more responses for your question/problem

Astronomical telescopes invariably give an image that is mirrored/flipped in one way or another.

Extra lenses, mirrors, or prisms would be required to give a right-way up image.
(Binoculars have 2 prisms in the light-path to give a right-way-up image)

In space, there is no up or down - so image orientation isn't that important.

Every element of glass in the light-path degrades the image slightly (no glass is 100% transparent, no mirror is 100% reflective)

In an astronomical telescope, light throughput, and image quality, ar FAR more important than orientation - so a proper astronomical telescope uses the minimum number of glass elements possible.
The (Very minor) trade off for best image possible, is that images are often 'flipped'
