Celestron Ultima LX EyepiecesCelestron Ultima LX Series parfocal eyepieces have 70-degree apparent fields of view to show 80% more sky than a standard Plossl. Their extendable twist-up eyecups are convenient if you wear glasses and the whole range is parfocal so little or no focus adjustment is needed when you change eyepiece. They are covered in shock-resistant rubber to prevent dents and scratches, and their no-slip finish is designed for secure handling, even in wet conditions. Their ergonomic contoured finish also prevents them from rolling off flat surfaces. These eyepieces incorporate the features that practicing astronomers need. |
