| The Celestron Axiom LX Series of ultra wide angle eyepieces use six to seven lenses to provide a huge 82° apparent field of view. Many observers say that using an Axiom LX eyepiece is more like looking through a “picture window” on deep space, rather than looking through an eyepiece. The view is so expansive that you have to move your head from side to side to see all of the dramatic full field of view. Each eyepiece is fully multicoated and computer-optimized for excellent correction of chromatic and spherical aberration and astigmatism. The lens edges are blackened for high contrast. They are parfocal, to minimize the amount of refocusing needed when switching between eyepieces within the Axiom LX series. They may not be parfocal with other eyepieces in your collection, however.
Each eyepiece has a twist-up rubber eyecup to shield your eye from ambient light. The 7mm, 10mm, and 15mm focal lengths have 1.25” barrels that are threaded for standard 1.25” color and light pollution filters. The 19mm, 23mm, and 31mm versions fit 2” star diagonals and focusers only. The barrels of these focal lengths are threaded for 2” filters. All have a no-slip wide rubber grip that assures secure handling, even when covered with dew. A groove machined into the chrome barrel of each eyepiece acts as a safety stop to keep the eyepiece secure should the focuser thumbscrew loosen slightly while using the eyepiece. Supplied soft rubber caps seal both ends of each eyepiece to keep them dust free. The eyepiece type and focal length are not merely painted on the body. They are engraved and paint-filled to remain clear and visible for life.
The eyepieces work well for low to medium high power observing with all telescope types and focal ratios. They have very good color correction, with virtually no field curvature, astigmatism, or ghosting. The optical performance is well corrected and sharp from edge to edge across the wide, wide field. The Celestron Axiom LX eyepieces are a good choice for observing large scale objects – open star clusters, nebulas, galaxy pairs like M65 and M66, etc. |
