IDAS NGS1 (ex LPS-D3) filter

IDAS NGS1 / LPS-D3 filter

IDAS LPS-D3(formerly NGS1) 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. As with other IDAS interference filters, the bandpasses are designed to accommodate the steep ray angles of fast optical systems.
