Problems with the ercecting lens

I just put together my new 78-9440 telescope and of course the images were upside down. When I put the erecting lens in I don't see anything anymore. It's all dark. Maybe I'm putting it in wrong?

Did you put the eyepiece into the diagonal? ------- after you put the diagonal into the telescope. Erecting lens is a DIAGONAL by the way. "erecting diagonal"

My telescope is showing upside down


All astro telescopes will normally show an inverted image. If you want to use it during the daytime you can fit an erecting prism between the lens and the focuser, like this

Why are the lens upside down help


It is normal for an astro telescope to show objects upside down, as when viewing astro objects this makes little difference. If you want to view terrestrial things, such as your neighbor's bedroom window, you can fit an erect image diagonal, such as

Without a porro-prism or a erect image diagonal, all telescopes show a reversed image. This is normal. There is no up/down in space. If you want to use the scope for terrestrial viewing, see first sentence. Do not use a erect image accessory for astronomy since it reduces the contrast.

I put the 1.5 erecting lens in, however, I am getting a tilted veiw not an upside down one without it How do I get the veiw totally upright?


Turn the diagonal, and the image rotates. Using the scope for star gazing it does not matter. Normally an astronomical telescope shows an upside down image--- no up or down in space. The erecting prism is only used for terrestrial viewing as the prisms inside are probably NOT multi-coated.

NO it is NOT missing a lens-- all astronomical telescopes show upside down images.

You can buy an "erecting prism" diagonal for terrestrial viewing, but you do not need it to view the night sky.

Here is an example of the erecting prism:

Upside down images


ALL astronomical telescopes show upside down images it is normal. Put the eyepiece with the LARGEST number written on it into the diagonal. Do NOT use the 2x barlow it is too much magnification for that small aperture telescope.
