Product Code: LPS-D1-48

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.

Light pollution suppression (LPS) filters are designed to suppress the common mission lines generated by artificial lighting, yet allow the important nebula emission lines to pass, thus enhancing the contrast of astronomical objects, particularly emission nebulae (see filter plots to see the effect on light pollution emission bands). The most recently introduced version (D2) has a bandpass designed to cope with the increasing trend of society's switch to LED lighting.

Unlike other light pollution suppression filters, IDAS filters are specifically designed for balanced color transmission using the IDAS unique Multi-Bandpass Technology (MBT) process. The balanced transmission allows color photographs to be taken with minimal color cast to broadband emission objects such as stars, galaxies and globular clusters.

LPS filters utilize the unique IDAS Ion Gun Assisted Deposition (IGAD*) coating technology for superior coating durability (quartz hardness) and safer cleaning. IGAD coatings also improve temperature and humidity stability of the filter performance, reducing spectrum shifts down to +/-1nm from the +/-3 or 4nm shift of standard coatings.

CCD imaging can also benefit, because although CCD imagers can already shoot through light pollution to some extent, including an LPS filter to the setup gives an added (signal-to-noise) edge.

It's more quality astro jumble - because as a filter, if it's been out of its packaging it's going to have a little dust, but optically it's in perfect condition.  Qualifies for our standard 12-month warranty.
