Product Description
Astrophotography is all about capturing light from billions of years ago. As avid astrophotographers, the STC team thought long and hard about how to create a filter to capture ultra-high contrast nebulae images - even with urban light pollution.
STC is the FIRST company in the world to create a dual-narrowband pass in ONE filter for deep sky astrophotographers. As experienced astrophotographers painfully know, shooting multiple images using two different filters would be necessary. Our Duo-Narrowband filter cuts the time required in half! Many have tried to copy our technology. None are successful in delivering our level of optical quality!
STC’s Astro Duo-Narrowband filter is specifically engineered to capture 7-12nm bandpass for H-Alpha, and Oxygen III nebula emission lines found in gaseous nebulae. With a transmission rating of greater than 85%, this is an astrophotographers' dream filter.
- Ideal for photographic the emission nebula with an urban or suburban foreground (Bortle scale 3~9).
- Enables high-contrast natural color images.
- Easy to use with ordinary digital or cool CCD cameras.
-
We also have clip filters versions for
Canon, Nikon, Sony, Fujifilm, Pentax, Olympus, Panasonic, Blackmagic Pocket Cinema Camera and Z Cam E-2.
Features
- Blocks urban light pollution. We coat the filter using an ion beam-assisted deposition (IBAD).
- 1mm Schott B270 optical glass prevents fogging by quickly absorbing and dissipating heat.
- Double-sided anti-smudge nano-coating is hydrophobic stopping moisture and mold.
- Anti-static coating keeps dust and fibers away.
- Super flat surface so you can capture clear images even when shooting at 8K and with 1200mm high-magnification telescope lens.
- Anodized aluminum eliminates surface reflection to avoid glare and ghost images.
- Aluminum rim treated with Teflon and black matte finish and easy to remove.
- Can be used with STC’s Astro-AdapterM48-M56 astronomical lens adapterring, 0.75mm Pitch (sold separately).
- Covered by the world’s first global filter warranty and repair service.
