About this product

Model:  idas-lps-d2-eosf
Part Number:  LPS-D2-EOSF

New Japanese-made IDAS D2 LPS filter designed to fit full frame Canon EOS 6D and EOS 5D Mark II cameras only.

Improves colour balance with colour cameras and also uniquely provides LED light pollution suppression.

Following from the highly successful IDAS P2 and D1 LPS filters, the D2 has been optimised for one-shot colour and modified DSLR cameras. The key concept of the D2 LPS is to reduce the reddish background cast whilst blocking as much light pollution as possible improving upon the already good colour balance of the P2 LPS and in addition block high/low sodium and white LED light pollution.

Light pollution suppression (LPS) filters are designed to suppress the common emission 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). 

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

IDAS 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, 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. The filter also blocks infrared so a separate IR blocking filter is not needed.

Note, however, that light pollution suppression filters are not a perfect substitute for dark skies.

The filters effective size is 37.2mm x 25.4mm, the filter substrate is 1.9mm thick. When in use, the camera mirror must be kept locked in the up position meaning that live view mode will need to be used.

The attachment instructions are available here but the process is relatively simple, remove the finder screen cover, lock the mirror up and insert the filter.
