There is nothing wrong. All astronomical telescope show objects as upside down. There is no up or down in space!

SOURCE: 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.

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.

SOURCE: 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

Why when I look through my telescope it's upside down
The image in astronomical telescopes are naturally upside down. This can be corrected using an inverting eyepiece . The reason this is the case, is that normally when viewing astronomical objects it doesn't matter if the image is upside down, so to minimise the loss of light that is the more important issue, unnecessary optical surfaces are eliminated. Terrestrial telescopes do naturally have inverting eyepieces as people expect to see objects the right way up.
Getting and inverting eyepiece will be cheaper the changing telescopes! :) Your eyes see everything upside down too, but your brain turns the image the right way up. The image in cameras is also upside down at the image plane, but the electronics turn it the right way up for you.

Looking through the telescope, the view is upside down. Also, it's not clear how properly put on the different mm lens.
All astronomical telescopes show upside down images-- it's normal. Put the eyepiece with the largest number written on it into the focuser. DO NOT USE the 2x barlow if you have one.

When I look into both the finderscope and the telescope, everything is upside down. We can't figure out if it's assembled wrong or what???
Hi there,

That is just the nature of the beast with most telescopes. When there are two concave or positive lenses in play, the object being viewed appears upside down.


The ways around this are using one positive and one negative (convex) lenses or adding a third lenses. The options for a third is sometimes referred to as an erector eyepiece.

As it stands, if it's upside down, it's assembled correctly

Best regards

Mike

Why is everything upside down
All astronomical telescopes show the view upside down. it is the properties of the mirrors/lenses. Ther is no up and down in space. You will get used to it.
For terrestrial viewing, you can buy a erect image diagonal (for refractors and SCTs) or a erect image eyepiece for refractors. This is not recommended for astronomy since it reduces contrast.

Just came into a used tasco 302048 . Everything is upside down!!!
the scope is made for both terrestrial viewing and astronomical. In order to see terrestrially upright, you need an inverting STAR DIAGONAL. The eyepiece will do nothing for inverting the image. you might have 2 diagonals in the kit that came wih the scope. the diagonal is the part that fits into the scope. then you place the eyepiece in the diagonal. if you have 2 diagonals , one is a 90 degree angle,(astronomical) and one is a 45 degree angle, (terrestrial). the eyepieces change the magnification of the image. the bigger the number (9mm, 20mm, 26mm,) the smaller the image. the smaller the number , the bigger the image gets. the number is inverse of the image. Hope this helps.

When i look thru eyepiece everything leans to one side
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--

When i look through the lens everything is upside down.
It is normal for a telescope to invert the image. There is no up or down in space so for astronomical use it does not matter.

The reflector telescope is not generally used for terrestrial viewing. However, image erectors can be purchased and are inserted before the eyepiece. This would make everything right side up.

Manual
You don't need a manual.
Upside down view through the telescope is normal. The scope is primarily for astronomical use and the concept of "up and down" is null in space.
If you want to use it for terrestrial viewing, you'll need an erecting eyepiece witch will correct up and down and left and right.

How do you use the red dot finder? and when I look throught the format eyepiece everything is upside down.... Thank you Stacie
Astronomical telescopes show all objects upside down and reversed-- this is not a problem; there is no up or down in space.

The red dot finder helps you point the telescope-- focus on a distant object and center it in the eyepiece.

Without moving the telescope -- adjust the red dot onto the object. Now you can use the finder to locate objects.
