Seeing land upside down

I'm just setting up my new telescope & everything seems to be good but when I'm checking if I can see through it, I'm seeing land upside down. Is this how it should be? How do I correct this?

    so do we need to change the lens or something to look at stars normally? How do we look at land without being upside down then? Change lens?

Yes that is the way it should be on your telescope.You need something like this for land base objects click here to see part.

    The 45 degree angle attachment goes on first then your lens.So you do need to buy the attachment just make sure the attachment you buy will fit your telescope lens connection.

This is not only perfectly normal, but for this type of telescope, imperative! Land (and everything else) seems upside down due to how the light is bounced between the mirrors. It can be kinde tricky to get used to, but it's the way all Newtonian reflectors (it's the type of scope you have, big mirror at the botom, smaller one that's at a 45 degree angle neer the top, and an eypece on the side of the tube) are.

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.

Is there any other way you can find out the serial and model name -number of an older meade telescope .Im looking for a replacement part(diagonal mirror ).Im seeing every thing upside down..I was told it I...

No they do not keep track of serial numbers only the main model number like LX200, LX90, ETX, etc etc--

Everything is ALWAYS upside down in an astronomical telescope. It's normal!

No up or down in outer space. Read my tips on my profile page.

They do make an "erecting diagonal" for terrestrial viewing. Just google "erecting diagonal".

We are seeing everything upside down. The CD talks about a special peice for seeing things right side up. What is this? How do we get it?

All astronomical scopes show upside down images-- it's normal nothing is wrong.

You can buy an erecting prism diagonal for terrestrial viewing like this one:

My scope on my telescope is seeing everything upside dow, is it supposed to do that? If not please tell me how to set it up. thek you

ALL astronomical telescopes show upside down images. It is completely normal.

For terrestrial viewing you can buy an erecting diagonal to flip the image over. Like this one:

We are seeing things upside down. Any ideas why?

Because ALL astronomical telescopes show upside down images. You would need more glass elements to ERECT the image. However you can buy an "erecting prism" for terrestrial viewing.

Same as the one I responded to.

That is normal for an astronomical telescope. For land, use a mirror diagonal to flip top/bottom. (look downward!) You can see what happens by rotating the diagonal as you view through the eyepiece; the image will rotate!

When viewing everything is upside down.

Yes, all astronomical telescopes show images upside down. There is no up or down in space.

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.

Everything is upside down its an inexpensive national geogra childs telescope when you look thru it everything is upside down

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.

Tasco galaxsee 46114675 telescope

The telescope is intended for astronomical viewing, where orientation is not that important. When looking at ground objects, it will be inverted and reversed (that is why binoculars have 2 sets of prisms). To use on land objects, you would need to add a 'terrestial viewing adapter', although those are generally intended for refractors - the newtonian has a diagonal that 'corrects' the image in 1 direction.
