Build and launch your own high-flying model rocket! There's no thrill quite like launching a model rocket, watching it Streak Skyward, reach Peak altitude, and then return gently to earth. When you build them, the thrill is even better. Thanks to Estes model rocketry, kids can explore the wondrous world of science while experimenting with different combinations of rockets, engines and accessories to better understand how rockets reach outer space..

Electron beam gun evaporation with Ion-assisted deposition coating technology for durability and resistance to scratching.
as well as stability on CWL (central wavelength) no deviation affected by temperature change.
Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass band and Optical density of off-band.
90% transmission of main nebula emission lines.
specifically the major emission lines of artificial light pollution.
Suitable for color CCD cameras and unmodified DSLR Urban optical filter can effectively suppress urban harmful light and improve the contrast of shooting target.
