Do you need a Barlow lens? A cost effective way to increase the magnification of your eyepieces. An extremely useful tool every amateur astronomer should have is a Barlow Lens. For example, if you were using a 20mm eyepiece on a telescope with a 1000mm focal length, you would have 50x magnification. …
Then, What kind of telescope do I need to see Jupiter?
A well-made 5-inch refractor or 6-inch reflector on a sturdy tracking mount is really about the minimum for serious Jupiter observing. Larger instruments will allow scrutiny of fine detail and subtle low-contrast markings.
Secondly, Can you stack Barlow lenses? Yes, stacking Barlow lenses is a common practice to effectively increase focal length by multiplying their individual focal lengths.
Can you use a Barlow lens with a zoom lens?
A Barlow and zoom works great but generally with faster scopes where it becomes somewhat obselete, as others point out.
What does a 3x Barlow lens do?
Description: When inserted between the eyepiece and telescope, this premium 3x Barlow lens triples the magnification of all your 1.25” eyepieces.
What can you see with a 100mm telescope?

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.
Are Dobsonian telescopes good for viewing planets?
Are Dobsonian telescopes good for viewing planets? Yes, Dobsonians are good for viewing planets. With a 6″ Dobsonian, you’ll get to see the polar caps on Mars, the rings of Saturn, and the moons and bands of Jupiter providing you ave the right viewing conditions.
Is a 2x or 3x Barlow lens better?
To put it simply, Barlow lenses are a cost-effective way to increase the magnification of your eyepieces. … Their effect is to increase the magnification of any eyepiece used with them, usually 2 or 3 times. As you’d expect, a 2x Barlow doubles your eyepiece magnification, whilst a 3x trebles it.
Are 5x Barlow lenses any good?
The SVBONY 5x Barlow lens provides magnification that is a bit worse than that of the 3x Barlow lens by Meade. I would guess that the real magnification of the SVBONY 5x Barlow is actually only around 2.5x. The image quality is acceptable. … This Barlow lens is very cheap but the quality is simply not good.
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 use a Barlow lens with a diagonal?
You can use a standard Barlow in a refractor, SCT, or other scope that uses a diagonal, either by inserting it between the telescope and diagonal or by (carefully) inserting it between the diagonal and the eyepiece. (The danger is that the long Barlow may protrude too far into the diagonal, damaging the mirror.)
What is the best focal ratio for a telescope?
For such objects, a focal ratio of f/10 or more is ideal. But if you want to see wide views of star clusters, galaxies, and the Milky Way, a lower focal ratio is better. You get less magnification, but you see more of the sky. Wide field telescopes have a focal ratio of f/7 or less.
Why are Barlow lenses blurry?
The Earth’s atmosphere also plays an important part in limiting the maximum magnification you can use. Instabilities in the atmosphere such as heat radiating from the ground and surrounding buildings, high altitude winds, and other weather conditions can cause your image to blur.
What can you see with a 130mm telescope?
You will be able to see Moon, Jupiter, Mercury(looks like a star), Venus, Saturn pretty well. Mars would be disappointing a bit. Its too small. You will get 65x with a 10 mm.
What can you see with a 70mm telescope?
The colorful bands and belts of Jupiter, as well as its four major moons, and the rings of Saturn are clearly visible in a 70mm telescope. Mars, Venus and Mercury are visible in a small scope as well, but are extremely reluctant to give up any detail because of their overwhelming brightness.
Are 50mm telescopes good?
50mm (2 in) telescopes are the most basic, entry-level, budget telescopes on the market. They are mostly targeted at kids and some of them could even fall into the toy category. We generally don’t recommend 50mm telescopes unless you are on a very tight budget or you are looking for a gift for a 5-year-old.
What telescope is best for viewing galaxies?

Do astronomers use reflecting or refracting telescopes?
Reflecting telescopes use mirrors to gather the light. … Refracting telescopes use lenses. There are different kinds of reflectors, but in general the refractors all follow the same basic design.
Which is better Dobsonian or Newtonian?
This makes the Dobsonian more robust, and better for carrying around without worry of damaging your telescope. Dobsonian tubes are twice the length of some standard Newtonians, as a Dob uses a flat secondary mirror as opposed to curved.
How big of a telescope do I need to see Pluto?
For the best chance of seeing it, you need very dark skies, a good telescope, a star chart, and abundant patience. If you’ve done this before, and have all of the above, then it’s possible to spy Pluto with a 5” telescope. Realistically, you’ll need at least an 8” scope is the best bet to go Pluto-hunting.
What lens is best for Mars?
Generally, a magnification of 30-50x the aperture (in inches) works well on nights of average-to-good seeing. For example, if you have a 4-inch telescope, try 120x to 200x. If you have an 8″ scope, try 240x to 400x. Again, experiment to get the best view each night.
What can you see with a 60 power telescope?
Jupiter and Saturn are two of the finest showpieces in the sky for the 60mm scope. Typically about a dozen asteroids will be bright enough on any given year to be seen with a 60mm telescope. Also, usually two or three comets appear that can be seen, sometimes more.
