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. 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.

The Triad 1.25-inch filter is housed in a 11mm tall ring, with 7.6mm height above the threads. The ring wall thickness is between 1.68 and 2.49mm - depending on production batch. Please double check to make sure this will fit your filter wheel or accessories.

Step up from your regular contrast boosting filter

A good experience with OPT on the delivery of my Triad filter from US to Australia. The filter is very good, allowing high contrast imaging in my bright suburban backyard, and under moonlight conditions on nebula targets. For use with my ASI294MC-Pro colour camera it is pretty much perfect match. A significant step up from my contrast enhancing filters, by a long way, giving me results quite similar to my narrow band filters. If emission nebula are your target then this filter is for you.

Wow!

I have managed to use this filter three times. Sort of experimenting. I have had excellent results using an ASI183 and a canon 70-300mm lens on an avx mount. While pricey, the filter does as advertised. This opens up a whole new level of photography for me. What I do. To understand yet is having a finished product like the example video. My stacked image does not require photoshop to pull out detail from a dark image. It is there plain as day prior to importing. I guess that is good!

Capture nebula details good

I can't get the color balance right even went I do for the picture as a whole the larger stars will still have the area green tint and glow. Do you have any pointers as I'm new to astro photo editing

New to the hobby?
