Celestron 2" Luminos Eyepiece 31mm (2 inch)

The Celestron Luminos 31mm (2-inch) Eyepiece is a high-performance, wide-angle astronomy eyepiece designed for serious amateur astronomers, telescope retailers, and observatories seeking exceptional optical quality. Engineered for deep-sky viewing, this advanced eyepiece delivers an expansive 82° apparent field of view, allowing users to capture more of the night sky with stunning clarity and immersive detail.

Built with a six-element optical design and fully multi-coated lenses, the Celestron Luminos 31mm provides bright, high-contrast, and razor-sharp images, perfect for observing faint nebulae, distant galaxies, wide star fields, and large star clusters. Its parfocal design ensures minimal refocusing when switching between other eyepieces in the Celestron Luminos range, making it an excellent choice for both retail telescope packages and advanced astronomy setups.

For added user comfort, the eyepiece includes a retractable eyecup suitable for both eyeglass and non-eyeglass wearers. The body is constructed from durable, anodised aluminium and finished with a textured rubber grip for a secure and non-slip hold, ideal for use in cold or humid observing conditions.

This premium 2-inch eyepiece is also threaded for standard 2" astronomy filters, ensuring compatibility with popular light-pollution filters, nebula filters, and colour filters used by deep-sky observers.
