The 6 Best Celestron 4 mm Lens (2023 reviews)

The celestron zoom eyepiece is the best feature-rich product on the market today. The zoom feature of this eyepiece is awesome. The telescope tube (optical tube assembly, or OTA) collects light from the sky and creates an image that you can explore with the eyepiece. It can be good to only carry a single eyepiece. The Integrated brass compression ring securely holds the eyepiece in place. The barlow makes the zoom more like 8 lenses than 4, and is nice to take the telescope beyond its limits then back quickly if you can't get a clear image.

This is a 1.25" diameter eyepiece which is the same size that the 102az uses. The ability to zoom on the fly makes keeping the target in the field of view incredibly easy. The eyepiece is well made and nicely finished with a smooth zoom mechanism.
