Enhance Nebula Imaging with Celestron Filter
Celestron Oxygen III Narrowband Filter is a 1.25" accessory designed for astrophotography and visual observation of nebulae. It isolates the doubly-ionized oxygen emission lines at 496 and 501nm, providing high contrast images of planetary and emission nebulae. The filter features an ultra-hard, vacuum-deposited coating that blocks the entire spectrum from 400 to 700 nm, eliminating color halos and enhancing detail. Made of high-quality, solid plane parallel glass, it is suitable for use with most standard telescopes. The filter's coatings ensure maximum light transmission and durability, making it ideal for amateur astronomers seeking professional-grade nebula imaging. Backed by a 2-year US warranty, it is supported by unlimited US-based support teams. Weighing just 0.01kg, it is compact and easy to handle, fitting standard 1.25" telescope accessories. The package dimensions are 3.0 x 1.0 x 3.0 inches, and it is manufactured in China.
