IDAS Filters Night Glow Suppression Canon EOS APS-C (64639)

The IDAS Night Glow & LPS Filters are specially designed to enhance the contrast of astronomical emission nebulae against skies affected by both man-made and natural sky glow. These filters maintain the color balance of broadband objects, such as galaxies, making them ideal for astrophotography. Their bandpasses are optimized for fast optical systems, ensuring minimal internal reflections and excellent performance.

Features:

• Ideal flat-top and moderate bandpass design

• High in-band transmission for superior image quality

• Steep bandpass edges to reduce internal reflections

• Blocks near-infrared (NIR) light up to 1200nm

• 2.5mm thickness, parfocal with other IDAS LPS filters

• Manufactured with IDAS-proprietary IGAD/MBT/UFP technology

Made in Japan!

Natural sky glow sources, such as upper atmosphere oxygen and sodium lines visible from high-altitude dark sky sites, are effectively blocked by these filters.
