By placing an extension tube between the Barlow lens and the eyepiece, you will increase the magnification of a telescope by two three or more times, depending on the size of the extension tube.
How can I improve my telescope?
By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 20 mm eyepiece used on a 1000 mm focal-length telescope would yield a power of 50x (1000/20 = 50).
How can I make my telescope Clearer?
Luckily, it’s easy to solve this problem. To avoid blurred images caused by high magnification, always start with a low magnification eyepiece and gradually increase it. In simple terms, always start with the big eyepiece and go as you add smaller eyepieces. You can start with a 20mm to 25mm and see if it works fine.
What makes a telescope more powerful?
The most important aspect of any telescope is its aperture, the diameter of its main optical component, which can be either a lens or a mirror. … In general, the larger a telescope’s aperture, the more impressive any given object will look.
How can a telescope seem farther?
To achieve low telescope magnification, use long-focal-length eyepieces. Telecompressor lenses can shorten the effective focal length of some telescopes, lowering the magnification of a given eyepiece used with that telescope. High telescope magnifications can be obtained by using short-focal-length eyepieces.
What is a good zoom for a telescope?
For most purposes, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters) . So you’d need a 12-inch-wide scope to get a decent image at 600×. And even then, you’d need to wait for a night when the observing conditions are perfect.
Why can’t I see anything out of my telescope?
If you are unable to find objects while using your telescope, you will need to make sure the finderscope is aligned with the telescope. The finderscope is the small scope attached near the rear of the telescope just above the eyepiece holder. This is best done when the scope is first set up.
Why is it black when I look through my telescope?
If you can see the shadow of the secondary mirror (black circle) and/or spider vanes while viewing through the eyepiece, the telescope is not focused. … If you want to make the focused image larger, you will need to use a higher power eyepiece.
Can you see galaxies with a telescope?
Galaxies are some of the most distant objects we can observe. … Unlike planets and bright stars, galaxies fade out as they expand. Even if a galaxy is bright, the most you might typically see is its core with a 4-inch telescope. Don’t be discouraged though, this is where the fun really begins.

What can you see with a 500mm telescope?
A 500mm telescope will yield a lunar image that’s about 5mm across in a DSLR camera with a full-frame, 35mm-format sensor; a 1,500mm telescope will produce a 14mm image, and a 2,000mm telescope results in an 18mm image.
What can you see with a 60x telescope?
60mm (2.3in) to 70mm (2.8in) aperture or equivalent
With telescopes of this aperture size, you’ll be able to see the moon and her craters, as well as some of the bigger planets.
How powerful does a telescope have to be to see the rings of Saturn?
The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times]. A good 3-inch scope at 50x [magnified by 50 times] can show them as a separate structure detached on all sides from the ball of the planet.
What’s the farthest thing you can see with the naked eye?
This week, try spotting the furthest thing you can see with the unaided eye. The Andromeda galaxy is a collection of a trillion stars lying 2.5m light years distant. Also known as M31, it is the nearest large galaxy to the Milky Way.
