Celestron Luminos 23mm Eyepiece
The Celestron Luminos 23mm eyepiece is a 2" six-lens design having an extremely wide 82° field of view (FOV) and minimal field curvature.
This combinations makes it especially suitable for use with flat field telescopes like the Celestron EdgeHD. This eyepiece provides you with great low power deep space views with telescopes having focal ratios right down to f/4.
Great for open clusters, nebulas, and globular clusters with any telescope, and is extremely effective with fast f/ratio reflectors and refractors. However, it should be noted that its wide field of view also makes it extremely handy for moderate power lunar and planetary viewing with much larger Dobsonians.
This 23mm eyepiece has a number of outstanding top of the line features which include retractable eyecups for eyeglass wearers, parfocal design, and a polished hard anodized aluminum barrel for robustness and high end visual appeal.
Every single eyepiece is fully multicoated and computer optimized for fantastic correction of chromatic and spherical aberration and astigmatism. Additionally the lens edges are blackened for high contrast.
The rubber gripping ring provides for secure handling and smooth control of the eyecup. The threaded barrel accepts 2" Celestron thread-in filters.
