Celestron 93230 8 to 24mm 1.25 Zoom Eyepiece Lens (Black)

I first could not achieve focus with the scope I have. This is probably because of the nature of Newtonian reflectors. However, with a zero-profile adaptor, I was finally able to achieve focus. It may also help to use an adaptor that is recessed (negative profile).The zoom feature is great, but image quality deteriorates rapidly at higher magnifications. Still, it is convenient to have the zoom feature, where you don't have to change eyepieces and re-focus while holding the telescope steady in the meantime. The build quality is excellent, although a bit on the expensive side. Recommended, if you have the right eyepiece adaptor (or scope).

This is the best eyepiece ever. Super easy to zoom in and view the moon and planets…although it only goes to a max of 8mm zoom. Much better than any other eyepiece that I have. If you have a telescope…go for it!

The best lens ever used. Great zoom. Clear images. Although a bit blurry when zoomed fully with a 2x Barlow. One must buy it to bring out the best of his/her telescope

EP sold by Galileo Telescope received in time. Excellent performance of the EP found when used without Barlow for the entire range from 8mm to 24 mm. But found very satisfactory from 10mm to 24 mm when used with 3x Barlow.

Really a good eye piece. I am not using the 10mm and 20mm eye piece anymore.
