Are Explore Scientific eyepieces good?
Both Explore Scientific eyepieces provide sharp, high contrast views with pinpoint stars throughout the FOV. The same was true with the 9mm Nagler and the 13mm Ethos. The views through all four were superior the 15mm Plössl, where the stars were not as sharp near the edges.
What are the best Celestron eyepieces?
For the money, the Celestron 8-24mm Zoom Eyepiece is one of the best telescope eyepieces and one of the most affordable in the market. Characterized for its practicality; you can zoom to any focal length between 8 mm and 24 mm in an instant without changing lenses.
How do I identify telescope eyepieces?
Eyepieces and telescopes are denoted by their focal lengths. Together, the two focal lengths produce a magnification, calculated as the telescope’s focal length divided by the eyepiece’s focal length (for more on this, read our guide to telescope stats).
Are Celestron eyepieces interchangeable?
They will work well in telescopes with a focal ratio of F/6 or more if they are of good quality. But you do not have to use only Celestron eyepieces with a Celestron telescope, you can use any eyepiece you want as long as it’s barrel fits the diagonal.
Where are TeleVue eyepieces made?
All TeleVue eyepieces are made in either Japan or Taiwan. The Plossls are one of their lines that to the best of my knowledge have always been manufactured in Japan, to TeleVue’s specs.
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.
Are Plossl eyepieces any good?
Plössl eyepieces are good all-around performers, producing sharp images at the center of the field, but they have only four lens elements. Better edge correction with a short-focus telescope is one of the things you pay extra money for, and sophisticated eyepiece designs have as many as eight elements.

What can you see with a 4mm eyepiece?
The Apertura 4mm Plossl eyepiece produces sharp, high magnification views of the Moon and planets, and, depending on the telescope, will also work great for double stars, planetary nebulae, and other deep sky objects. Like most Plossl eyepieces, the High Point 4mm has a 52º apparent field of view.
What does Plossl mean?
The Plössl is an eyepiece usually consisting of two sets of doublets, designed by Georg Simon Plössl in 1860. Since the two doublets can be identical this design is sometimes called a symmetrical eyepiece. The compound Plössl lens provides a large 50° or more apparent field of view, along with relatively large FOV.
Are Celestron eyepieces good?
Celestron X-Cel LX Series Eyepiece is another excellent product from Celestron. It works well for all 1.25-inches telescope, and it is adapted to accept colored and moon filters. This telescope eyepiece is affordable and comes in a protective box that makes it durable.
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.
Are 2 inch eyepieces worth it?
Typically 2″ Eyepieces are used for lower magnification and or wider field of view. A 2″ barrel will allow for a wider Apparent Field Of View through the Eyepiece that a 1.25″ wouldn’t normally allow. So if you had a 2″ and 1.25″ 32mm EP, the AFOV in the 2″ would be greater, probably much greater.
Do I need 2 inch eyepieces?
2″ Eyepieces vs.
It’s a matter of lens size needed, not optical quality. You only need a 2″ size eyepiece when you are exploring for low magnification eyepieces with wide fields of view. You do not need a 2″ barrel on a short focal length eyepiece, even on the very finest 1.25″ short focal length eyepiece.
What type of telescope is a Dobsonian?
reflecting telescope
A Dobsonian is a reflecting telescope (uses a mirror, not a lens) in the same design as a Newtonian telescope (concave collecting mirror is at the rear of the telescope tube, eyepiece is on the side of tube, up near the front).
Who makes TeleVue?
About Al Nagler
Below it are five 82° Field Tele Vue Nagler Eyepieces, some of the accessories that contribute to high image quality. The telescope and eyepieces are representative of a family of optical equipment manufactured by Tele Vue Optics, Inc., Suffern, New York.
Where are TeleVue telescopes made?
Chester, New York
Every TeleVue refractor is assembled, collimated and tested at their facility in Chester, New York.
Are TeleVue eyepieces any good?
The DeLite eyepiece series from Tele Vue delivers an optically excellent view together with the option to physically adjust the distance of your eye from the eye lens, whether you wear glasses or not. This makes it really easy to place your eye at the correct ‘eye relief’ to get the best view possible.
What can you see with a 100mm telescope?
