OPT Radian Triad Tri-Band Narrowband Filter
Dealing with light pollution is the biggest challenge for astrophotographers. Until now, taking narrowband color images involved the complexity and high cost of upgrading your camera with a filter wheel, 3 or more filters, adapters, and software. Now there is a more affordable all new option that delivers dramatic detailed images even in bright settings.
Triad is a revolutionary multi-band filter technology that passes only H-alpha, H-Beta, and Oxygen III emission lines enabling any color camera to now capture RGB narrowband images. Because you don't need to buy three seperate filters, it’s an affordable single-filter option guaranteed to dramatically reduce light pollution and increase your signal even in bright urban and moonlight settings.
Engineered specifically for use with DSLR, CMOS, and CCD color cameras, Triad features advanced multi-coatings and extreme tolerance glass, making it the most consistent and accurate light pollution suppression filter available. 100% American made.
