About this product

Model:  idas-lps-p2-48sct
Part Number:  LPS-P2-48SCT

The Japanese-made IDAS P2 LPS is in our opinion the BEST Light Pollution Suppression filter for astro photography with DSLR, colour and mono CCD cameras. 

This SCT Filter Adaptor set is for direct attachment of an IDAS Light Pollution filter to the back of a Celestron or Meade SCT. 

The filter holder consists of Borg components 7424 and 7502 which hold the LPS filter between the two pieces. The telescope-side piece is a female SCT-thread while the eyepiece/camera side provides a male SCT-threaded interface, making it easy to insert the filter into an SCT system.

The filter holder can be used with other 2" filters if you wish.

 

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.

Your Question:

Q1. What is the difference between the IDAS D1 filter and the P2 Filter? Which is best for a DSLR?

The only difference between the P2's and the D1's is that the newer D1's block a little more of the red, specifically the SII emission area. Whilst there's not usually much SII available it does help the overall colour balance of an image.

This effect is most useful on a DSLR - on a mono camera you'd be using other filters and we'd recommend a P2 filter. For DSLR's the D1's are more suited.
