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.

Do not know where you live but humidity will fog the eyepiece. Put the scope out with the covers on for at least one hour to reach thermal equilibrium. Use the lowest power (highest number) eyepiece first.

Cant get an image.Is it right that the view finderimage is upside down


The image of all astronomical telescopes are upside down (SCTs are upside down and reversed). RACI (right angled, correct image) finders do produce a right-side up image. For daytime use a erect image prism eyepiece.
Follow below instructions (except 7 in your case)

  1. Get Stellarium or another fine astronomy program
  2. During the day, point the telescope at a part of the landscape about 100 yards away.
  3. Use the lowest power eyepiece (highest number) in the focal tube.
  4. Center the landscape object in the telescope.
  5. Align the finder scope so that it points exactly where the main telescope is.
  6. At night, leave the scope out to reach thermal equilibrium (about an hour for small reflectors and refractors)
  7. If the scope is on a EQ mount, polar align.
  8. Point the finder at the moon. The moon should be in the main scope also.
  9. Practice finding the moon before you start on the planets
  10. Once you are comfortable with the moon and planets, you can go for the deep sky objects

Viv-tel-76700


viv tel 76700 takes both size eyepieces. There is a small sleeve in the eyepiece holder that reduces the size to .965in(cheap 2 element plastic pieces), take it out and use 1.25in( 4+ element glass) pieces and you will see better. This scope has many names on it, search 76700 telescope and you'll see.

Hello, I m using the 60700 Telescope but the image i see in lens is very blurred, i assembled my telescope as per Manuel instruction but still i see upside down image with blurred effects. I tried several...


All astronomical telescopes show upside down and or inverted images-- it's normal nothing is wrong. You are applying too much magnification. Do not use the 2x barlow-- and start practicing how to focus using only the eyepiece with the largest number written on it which is your LOWEST power.

You can practice focusing during the daytime on a distant object like a telephone pole or a building.

Dear Sirs, I got a Barska telescope 84-4363 (lens 76700), when looking through it the picture is upside down. There is a additional mirror sent with, but the picture then is not clear anymore. Since there...


All astronomical telescopes have upside down images -- there is no up or down in outer space. This is probably a REFECTOR style telescope. The part with the small mirror is called a diagonal. Certain types of diagonals called "erecting diagonal" can be used to flip the image right side up for terrestrial viewing. You do not need them for star gazing.

On a tasco851tr why is the image upside down? also where can i get instruction booklet and are there various lenses? this one has a 20 power only thanks fred


All astronomical telescopes show upside down images. It's normal, no up or down in space.

You will not find an instruction manual. What you need to do is to learn a little Astronomy by buying these two books.

Turn Left at Orion

Nightwatch

Both available on amazon.com.

Why is my picture upside down during the daytime ? on box says reflector. am i wrong when i had read that these have view as you would with binoculars


All astronomical telescopes have upside down images. There is no up or down in space; and it requires more glass elements to turn the image upright. More glass means less light will reach your eye.

How to use Power telescope 76700.


You will not find an instruction manual for that small telescope. However Meade maintains a web site for their telescopes. Look under REFRACTOR for one similar to your scope.
