IDAS

Optimized light pollution suppression filters for one shot colour CCD and modified DSLR cameras. Not only do these filters block out the majority of the light pollution, they also reduce the red cast improving on the colour balance.

The P2 is the most popular filter for suppressing light pollution with modern CCD, CMOS and DSLR cameras. Japanese made for the highest possible quality.

IDAS Night Glow Filters enhance the contrast of astronomical emission nebulae against a sky with both man-made and natural* sky glow sources, yet preserve color balance of broadband objects such as galaxies.

IDAS NB Filters are designed to enhance the contrast of emission nebula, yet accommodate the filter spectral shift* when used with modern fast optical systems.

IDAS NBZ Filters are designed to enhance the contrast of Hα and OIII emission nebula, yet accommodate the filter spectral shift when used with modern fast optical systems. This dual-band filter is ideal for one-shot color cameras as well as mono-color astronomical cameras.
