Détails
The spread of urbanization and light pollution are becoming a growing problem for amateur astronomers and astrophotographers in recent years.
Current solutions to the problem can be very expensive and usually include the purchase of a monochrome camera, several types of narrow band filters and a filter wheel.
Its triple-bandwidth has been designed for the new generation color CMOS cameras
The convenience and effective cost of this filter allow astrophotographers to shoot a rich selection of astronomical objects, even in heavily light-polluted areas.
This filter effectively isolates the emission lines not only of emission nebulae but also of galaxies, clusters or globular clusters and reaches a maximum transmission of up to 97%.
The performance of this filter delivers superb images with excellent light pollution control.
Recommended for: Reducing light pollution, Increasing contrast for emission nebulae, Saving processing time
Recommended use for: color CMOS, monochrome
