How do you fix an inverted scope?
One of the biggest surprises that beginner astronomers have is when they find that the view they are seeing through their telescope is upside down or backward. To correct upside-down viewing equipment known as a Diagonal can correct the image and turn it right-side up.
Do you need a finder scope?
Why do we need a finder scope? Finderscopes are generally very low in magnification- between 6x and 9x the naked eye- while some have no magnification at all. Without the finder scope, locating objects simply by looking in the main telescope would be very difficult.
How do you use the red dot finder scope?
To use the Finder, simply look through the sight tube and move your telescope until the red dot merges with the object. Make sure to keep both eyes open when sighting. Like all finderscopes, the Red Dot Finder must be properly aligned with the main telescope before use.
What does a star diagonal do?
A star diagonal, erecting lens or diagonal mirror is an angled mirror or prism used in telescopes that allows viewing from a direction that is perpendicular to the usual eyepiece axis. It allows more convenient and comfortable viewing when the telescope is pointed at, or near the zenith (i.e. directly overhead).
What does a Barlow lens do?
The Barlow lens, named after Peter Barlow, is a diverging lens which, used in series with other optics in an optical system, increases the effective focal length of an optical system as perceived by all components that are after it in the system. The practical result is that inserting a Barlow lens magnifies the image.

Is the image in the finder scope always upside down?
The image in the finder scope is always inverted unless it has a correcting prism. To get a correct way up image you need to use a RACI Finder, but do not worry you soon get use to the upside down image. The image in the finder scope is always inverted unless it has a correcting prism.
What happens when you look at a telescope upside down?
It can be a surprise the first time you look through a telescope or a finder scope to realize the image is upside down (inverted). The image is different from what you see with a naked eye. It will be reversed left to right, upside down, at a strange angle, or all of these. Don’t worry. Optics work that way.
Is the image in the RACI finder always upside down?
The image in the finder scope is always inverted unless it has a correcting prism. To get a correct way up image you need to use a RACI Finder, but do not worry you soon get use to the upside down image.
Is it OK to look at the sky upside down?
November 15, 2018. If your viewing target is upside down when you use your telescope, don’t be alarmed! Astronomical telescopes are designed to produce an upside-down or inverted image. This is not a problem when looking at the sky since orientation relative to the ground does not matter for a planet, star, or nebula.
