Are Skywatcher eyepieces any good? Viewing through this eyepiece was a wonderful experience and it certainly produced the ‘wow factor’ on a number of viewed objects at 65X. Objects snapped into focus without the need for searching. The view was flat and crisp with good contrast and ample eye relief. I noted the edge of the view was black and sharp.
Then, How do you use a Barlow eyepiece?
Secondly, What are the different telescope eyepieces? What are the different types of eyepiece?
- Plössl eyepiece. Plössls have a wide field of view (around 52°), so they can be used successfully for planetary as well as deep-sky viewing. …
- Radian eyepiece. The Radian is one of the newer types of eyepiece on the market. …
- Nagler eyepiece. …
- Orthoscopic eyepiece. …
- Barlow lens.
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.
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.
What can you see with a 25mm eyepiece?
25mm – 30.9mm Telescope Eyepieces: These are extended field eyepieces for longer focal length – good for large nebula and open clusters. For shorter focal length, they are fantastic for large objects such as the Orion nebula, views of the full lunar disc, large open clusters and more.
How good are zoom eyepieces?
They tend to occupy the middle ground of focal length/magnification, so you may still need a very high and low magnification eyepieces (short and long focal length, respectively), but a zoom could handle everything in between for you. On the face of it, they are a fantastic tool, but nothing is perfect.
How do I choose an eyepiece?
For most observers, an apparent field of 60° to 70° is a good choice for an eyepiece. If you have more to spend, you can consider an AFOV of 82° eyepiece, but these eyepieces tend to be expensive and bulky at the longer focal lengths, and so they tend to offer the best value when used for medium and high magnification.
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.
Are Barlow lenses worth it?
Every amateur astronomer should consider the Barlow lens as an extremely useful tool. One of the greatest advantages of say, a 2x Barlow Lens is that it doubles the magnification of your eyepieces, which can also be effectively seen as doubling your eyepiece collection.
Can you stack Barlow lenses?
Yes, stacking Barlow lenses is a common practice to effectively increase focal length by multiplying their individual focal lengths.
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 magnification do you need to see Jupiter?
Generally a magnification of 30-50x the aperture of your telescope (in inches) works well on nights of average seeing. So if you have a 4-inch telescope, try 120x to 200x. If you have razor sharp optics and steady sky, you can get away with even more magnification.
How Saturn looks through a telescope?
Despite its beauty, Saturn appears quite small in a telescope. … You can never see Saturn through a telescope quite as well as you would like to. Once you get the planet in view, pop a low-power eyepiece in your scope. At 25x, you’ll see Saturn as non-circular, and 50-60x should reveal the rings and the planet’s disk.

What can you see with a 90x telescope?
Thus a 90x magification on a very large (wide) telescope would let you see a very large number of things (if you are in an area where the sky is dark), but 90x on a small telescope would let you see a number of interesting things (the Moon, planets, some nebulae and star clusters) but not relatively faint objects.
What can I see with a 90mm telescope?
c) Deep Sky Objects: dozens of globular clusters, emission nebulas, planetary nebulas, and galaxies. Also, all of the Messier objects, although most galaxies will remain relatively featureless hazy patches. This is an example of Mars as seen through a telescope with a 90mm aperture.
Can you use a Barlow lens with a zoom eyepiece?
Basically, any eyepiece can be used with a barlow provided the the combination doesn’t exceed the useful magnification.

What size telescope eyepiece do I need?
The largest-focal-length eyepiece you can use with your telescope is easy to calculate: multiply the focal ratio (the focal length of your scope divided by its aperture) by 7. For example, your Newtonian scope is f/5: the largest-focal-length eyepiece you should use is 35 mm.
Which eyepiece is best for viewing stars?
Orthoscopic: Also called Abbe eyepieces, Orthoscopics have a narrow field of view but produce nearly perfect images thanks to a simple but effective lens configuration. Orthoscopic eyepieces are best for lunar and planetary observing.
