Hutech IDAS Night Glow Suppression Filter for Canon EOS R and RP

Hutech IDAS Night Glow Suppression Filter

The IDAS NGS1 is a broadband nebula filter that allows the photography of gas nebulae, star clusters and galaxies even from close to cities. The filter is just as suitable for luminance images with monochrome cameras as it is for images with color cameras. The color balance is maintained well. The filters are also suitable for very fast optics without transmission losses. The most important spectral lines of hydrogen (Hα, Hβ, Hγ), oxygen ([O III]), sulfur ([S II]) and comets (C₂ in the head and in the coma, CO⁺ in the ion tail) are allowed through.

The general features of the IDAS NGS1 filters at a glance:

High transmission and steep edges, thus optimal use of the wavebands important for astrophotography

Steep bandpass edges minimize internal reflections

No IR cut filter is required as the NIR is blocked up to 1200 nm

Allows up to 4x longer exposure time

IDAS proprietary IGAD/MBT/UFP quality

Made in Japan
