Question about National Geographic 76AZ (525 x 76mm) Telescope
Chimney is correct-- THERE is NO up or down in space-- so astronomical telescopes present the image upside down-- rather than introducing more GLASS-- between you and the sky object ; just to turn it right side up. they all work this way.

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.
