A new revolution in Optolong home astrophotography, a new filter that marks the evolution of the already known L-eXtreme

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, different types of narrowband filters and a filter wheel.

The L-Ultimate filter is a practical solution for all amateurs who want to use their telescope from urban and sub-urban areas

Its dual bandwidth has been designed for color CMOS cameras
The convenience and cost effective of this filter allows astrophotographers to shoot a rich selection of astronomical objects, even in heavily light-polluted areas.

Perfect on color cameras, a must have in addition to L-Pro and L-eNhance and L-eXtreme

This filter effectively isolates the emission lines of the nebulae in H-Alpha and OIII and reaches a maximum transmission of up to 93%.

The cut of the passband is only 3nm.

The performance of this filter delivers superb images with excellent light pollution control.

Recommended for: Drastically reduce light pollution, Increase contrast for emission nebulae, Save processing time

Recommended use: Color CMOS
