Frequent question: What should I look for when buying a telescope?

As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. Dobsonian telescopes, which are reflectors with a simple mount, provide lots of aperture at relatively low cost. A larger aperture lets you see fainter objects and finer detail than a smaller one can.

What magnification telescope do I need to see planets?

Experienced planetary observers use 20x to 30x per inch of aperture to see the most planetary detail. Double-star observers go higher, up to 50x per inch (which corresponds to a ½-mm exit pupil). Beyond this, telescope magnification power and eye limitations degrade the view.

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.

Which is better a refractor or reflector telescope?

If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.

Can you see Pluto with a telescope?

Can I See Pluto With a Telescope? Yes, you can see Pluto but you’ll need a large aperture telescope! Pluto resides at the very edges of our solar system and shines only at a faint magnitude of 14.4. … The dwarf planet is 3,670 million miles away from the Sun and looks just like another faint star in your telescope.

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.

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.
