The 8 Best Celestron 25 mm Eyepieces (2023 reviews)

A Barlow essentially doubles the telescope optical focal length and thus magnifying power. It features a 40 to 60 degree field of view and 15 to 18 millimeter eye relief. It is fast and easy, and lets you examine any object at various magnifications without requiring you to physically change eyepieces. It will narrow in it's field of view as it magnifies the center.

This is a good eyepiece considering that it zooms from 24 mm to 8 mm. Nexyz gives you the power to place your phone on the platform, center it over the eyepiece with the x and y knobs, and then move up or down over the eyepiece until you have the entire field of view in your shot. It is compatible with any telescope that accepts 1.25” eyepieces. It comes with a sturdy individual case, easy to pack and attach.

Why We Like This:

A great way to add extra horsepower to your telescope
Eye relief is good at high power
Fits perfectly with standard scope receiver
High recommend over single mag lenses

Best For An entry level: Celestron stock Eyepiece

Buy on Amazon

Most of the eyepieces from this series are very sharp with great field of view and crispy images. The Celestron Travel 50 and 70 use standard 1.25" eyepieces so they can use any brand of 1.25" eyepiece. The image is very sharp and crisp and colors and details of the planets are clearly visible with a stable mount.

The shorter focal length eyepieces (smaller number of millimeters) will give higher magnification. If the seeing conditions are calm and steady, the eyepiece will provide a high powered view. It is great for viewing saturn or jupiter and splitting double stars. The eyepiece will fit your focuser. With a 1200 mm focal length, the 7mm would be great for planets and 25 mm good for deep sky objects. They are also much lighter and easier to work with.

Customers say that getting a celestron len, along with eyepiece is useful.

Why We Like This:

6 mm are bright and clear and maintain good performance across the field
Good investment for long term

Best For clusters: Celestron Great Eyepiece

Buy on Amazon

Celestron makes beautiful and great eyepiece with classic and smartly choosen materials. A good 18 mm or even a 25 mm eyepiece plus a good Barlow 2X will give you excellent views of planets. It will work fine with any 1, 25" focuser, no adapters or attachments required. It allows significant vibrations to rock the scope while viewing.

This eyepiece would provide 36 power through your scope, so you would be looking at the whole moon. It will drift rapidly across your field of view so each time you adjust the scope you will lose seeing time while vibration settles out. It's much better than the Hyperion's fold down, rubber arrangement.

The scope comes with a 90 degree star diagonal which puts the bird right way up but of course left is right and right is left with the star diagonal.

Best For Planetary Image: Celestron Apparent Field

Buy on Amazon

If you are looking to buy a suitable eyepiece for your daily purpose, you cannot go wrong with this pick. Celestron makes a zoom eyepiece which is handy for finding what you're looking for and then zooming in. Using a 40mm eyepiece in this scope will give you a very low magnification of 18x, which is well suited for open clusters, lunar observation and sweeping wide regions of target-rich constellations such as Scorpius and Sagittarius. The images are very clear and bright, edge to edge, with a great field of view.

The eyepiece gets the heaviest use with star clusters, mainly hunting globular clusters. It fits in an inch and a quarter opening. The harsh color distortion around the moon is gone and the larger glass and field of view means less eye strain. This eyepiece works well in the slower scope, where it gives bright, sharp images. It's definitely beginner friendly and the 40mm size makes for wonderfully bright images.
