Are Celestron Eyepieces Any Good?
Are Celestron eyepieces any good? Bottom line: The eyepieces in the Celestron Kit are definitely not trash and can provide very good views. This is based on personal experience with some of the eyepieces in the set. The shorter focal lengths are short on eye relief, I prefer longer eye relief but they are usable.
Which eyepiece is best for viewing planets Celestron?
What eyepiece is best for planets?
The focal length of the telescope is 900mm, so to achieve the maximum useful magnification, then a 4.5mm eyepiece would be ideal. One of the best parts about planetary viewing or imaging is that since the objects are so bright, you can do it just about anywhere regardless of light pollution.
What is the difference between Plossl and Kellner?
Kellner eyepieces have decent eye relief, a fair field of view (45 degrees) and little curvature of field. The Plossl eyepiece is composed of two doublets, which are identical to each other. For this reason, you will also hear it called a symmetrical eyepiece.
How do you zoom in on Celestron telescope?
Additionally, a simple way to increase magnification is to use a Barlow lens in addition to your existing eyepiece. A 2x Barlow will double the magnification of any existing eyepiece, a 3x Barlow will triple it, and so on.

What is a Barlow lens for a telescope?
A Barlow lens is the astronomy accessory that keeps on giving! Insert it between your eyepiece and your telescope to get double the magnification instantly. Let's say you have two eyepieces in your accessory case, a 10 mm and a 25 mm.
Which telescope lens is stronger 10mm or 20mm?
The larger one is normally between 20mm and 25mm and is the lower power (lowest magnification). The smaller (higher magnification) is normally around 10mm. A larger image to start with will allow the eyepiece to produce a larger image to view (higher magnification).
What eyepiece 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 eyepiece is best for Jupiter?
Best eyepiece for viewing Jupiter
Because of this, it is one of the few planets where you don't want to max out on magnification to get the best views. Jupiter looks best in the 100x-200x range for enthusiast-level telescopes.
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.
What is a Nagler eyepiece?
In the early 1980's, Al Nagler created a small sensation when these eyepieces were introduced. His goal was to create a "spacewalk" feeling when looking through these eyepieces. This is accomplished by sticking a barlow-like lens group inside the barrel of a long focal length eyepiece.
What magnification do I need 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.
Are Plossl lenses any good?
The four element Plossl design is perhaps the most popular telescope eyepiece design on today's market and just about every manufacturer makes one. It provides excellent image quality, good eye relief and just about all of them have an apparent field of view of about 50 degrees.
What is a Kellner lens?
Kellner: This design improves on the Ramsden by replacing the eye lens with an achromat, leading to better color correction. These offer a very sharp, bright field at low/medium powers, but very short eye-relief at short focal lengths (high power). It offers excellent sharpness, color correction, and contrast.
Why can't I see anything through my Celestron telescope?
If you can't see anything clearly through your telescope using your eyepiece, try using a different eyepiece; switch from a high-power eyepiece to a lower-power (ex: 4mm to a 20mm eyepiece) instead. Always start with the lowest power eyepiece (the one with the highest number in millimeters printed on it).
How do you buy telescope eyepieces?
Usually, you'll want to start with low power (i.e., long eyepiece focal length, such as 25 mm or 30 mm) to get the object in the field of view of the telescope. Then you might want to try a slightly higher-power (shorter focal length, maybe 18 mm or 15 mm) eyepiece and see if the view looks any better.
How do telescope eyepieces work?
How do eyepieces work? An eyepiece works by taking the light that's captured and focussed by your telescope and magnifying the image that is seen by your eye. The eyepiece needs to do this effectively if you're to get a really good view of that celestial object.
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 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.
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.
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.
How big of a telescope do I need to see the flag on the Moon?
The flag on the moon is 125cm (4 feet) long. You would require a telescope around 200 meters in diameter to see it. The largest telescope now is the Keck Telescope in Hawaii at 10 meters in diameter. Even the Hubble Space telescope is only 2.4 meters in diameter.
What can you see with 700mm telescope?
With a 70mm telescope, you will easily be able to see every planet in the Solar System. You will also be able to take a great look at the Moon and clearly distinguish most of its recognizable features and craters. Mars will look great.
Is 300x magnification good?
There is still a practical upper limit though—about 300x is the highest useful magnification even with excellent seeing.
How big of a telescope do you 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.
Can you see Jupiter with a 10mm lens?
In most cases you need two to three eyepieces of different powers, say a 25mm, 15mm and a 10mm and a barlow lens. A 2X barlow will double the power of an eyepiece practically turning a 25mm into a 12.5mm. If you have any filters, an 80A Blue seems to work fairly decent on Jupiter.
What eyepiece is best for deep sky objects?
With 40 mm eyepiece, you can observe the largest deep-sky objects like the Andromeda galaxy, the Pleiades, Rosette Nebula, Orion Nebula, etc.
What magnification do you need to see Mars?
To see much detail on Mars you would need in excess of 100x magnification (same for Saturn, less for Jupiter), and ideally a lot more. Your scope should be able to manage 100x.
