Focal Length: 8-24mm

Zoom eyepiece brings great convenience to visual astronomy, it is available to change the focal length and magnification by rotating the eyepiece. It covers the range of several eyepieces and offers better observing experience when to get the perfect view of the moon or a planet.

Field of View: 38 - 56°

The apparent field of view ranges from 38 degrees at 24mm to 56 degrees at 8mm, and the shorter the focal length, the larger the magnification and the narrower the field of view.

FMC & Edge Blackened

The 7 elements in 4 groups optics are fully multi-coated optics and glass blackened edge ensure a great light transmission and no stray light, and you would get a clear, sharp and accurate images.

Eye Relief: 18-19.5mm

Long eye relief and twist-up eyecup ensure observing with or without glasses, and ensures a comfortable observing experience.

1.25” Interface & M28.5*0.6

The eyepiece interface is 1.25” and the thread size is 28.5*0.6, to connect to astronomical telescope with 1.25” interface and 1.25” filter, for a better observation experience.

Safety Undercut

Here is a safety undercut on the barrel, the eyepiece won’t suddenly slide out of the telescope during being used in observing.
