The apparent field of view and the usable eye relief to stay the same as the focal length changes.

Smooth zoom action with click-stops at 3, 4, 5, 6,7 and 8mm for quick changes to precise preset magnifications.

Parfocal across the entire zoom range (minor tweaking may be necessary, however).

Fully multi-coated optics; the eyepiece ensures that each glass surface has multiple layers of coating to obtain a better image quality

All-metal structure; the eyepiece has fine workmanship and fine materials

Matt blackened; the edge of the lens is matt blackened to prevent stray light interference

25mm large eyepiece; plossl eyepieces with 25mm and longer focal lengths are good choices for spectacle wearers; can better protect the eyesight of the observer

2 sets of 4-piece optical structures; the super plossl eyepiece structure has good compatibility

The SV207 series are classic Plossl eyepieces that offer higher performance than the majority of eyepieces supplied with telescopes.
