Yes all astronomical telescopes are upside down! No up or down in space!

You can buy an erecting diagonal for about $45 from Orion Telescopes to use for terrestrial viewing.

The image is upside down


Yes, all astronomical telescopes show upside down images--- no up or down in outer space-- and you would need more lenses in the light path to erect the image.

When looking thru the lens everything is upside down


Astronomical telescopes normally show an upside down image. There is a good reason for this- erecting the image needs more bits of glass in the light path, which reduces the amount of light and increases aberrations. Even if this is only slight, astronomers prefer to avoid it, and they don't really care which way up the Moon or Jupiter appear.

It is possible to fit an erecting prism or eyepiece to most astronomical telescopes, and some of them come with one.

Everything is upside down


Astronomical telescopes produce an upside-down and reversed image (image is rotated 180 degrees from an upright position) since this doesn't matter when you are looking at things in the night sky. Accessories are available for rotating the image to an upright position, but most of those accessories do not work well with Newtonian style reflector telescopes such as the 114EQ reflector.

In space there is no up down right or left-- all astronomical telescopes show land objects upside down-- you can buy an erecting prism to use for terrestial viewing here--

Things are upside down looking thru the eyepiece on main telescop


If things are upside down in your telescope, you probably have a reflector telescope.it has curved mirror in the sealed end.take off the cover near the finder and point in the general direction of what you want to see.Make adjustments with the stuff on the mount.If you are viewing terrestrial objects, you will need an inverting lens to correct the image.It is called a Barlow lens and is much longer than the other lenses that come with the telescope.Good Luck

Everything is upside down thru the lens


Reflector telescopes are design for looking at stars, and in space there is no right side up. Try taking it out at night and look at the moon. Your telescope is performing just as it should, there are no problems with upside down views when looking at objects on the ground.

THINGS UPSIDEDOWN


It's the nature of the way telescopes work that means all images are seen inverted. For astronomical use, this isn't really a problem.

You can buy an "image erector lens" to correct the image and see it rightside-up though.

Inverted image


All images in astronomical telescopes are upside down and reversed-- this is normal. There is no up or down in space. Reversing the image just adds more GLASS to the light path.
