Reach for the Stars: STC Announce World-First Technology with Astro Urban Series Filters

Leading Taiwan-based optics and photo/video accessory manufacturer, STC, has revealed a brand-new series of specialist astrophotography filters for professional and enthusiast photographers. Say hello to the all-new STC Astro Urban Sky LRGB and SHO Filters.

STC expands its range of high-quality, specialist filters with the arrival of the brand-new Astro Urban Sky Series.

As STC continues to create innovative accessories for the global photography and videography communities, the new STC Astro Urban Sky LRGB filter is the world’s first anti-light pollution, ultra-low halo RGB monochromatic filter and has been designed for shooting astronomical deep-sky objects in areas with heavy light pollution such as urban spaces.

The new filter arrives to deliver enhanced results for astrophotographers everywhere, extending the amount of exposure, boosting the colour channel to achieve the highest contrast and stunning images with relative ease.

The new LRGB filter can be used in conjunction with the new STC Urban Deep Sky SHO filter to emphasise the characteristics of star clusters and to develop unique bright colours from the celestial body.

STC Astro Urban Sky SHO Filter

The STC Astro Urban Sky SHO Filter accurately identifies the three crucial spectral lines, Ha, SII and OIII, in order to enhance the colours of nebulae and galaxies. The strict parfocal process is closely integrated with the German SCHOTT® B270 optical glass.

With a narrow bandpass of 7nm and a 95% penetration rate, SHO filters isolate specific spectrum produced by interstellar clouds. With the application of the new STC Astro Urban Sky SHO Filter, astronomical monochrome CMOS or CCD cameras can easily capture the colours of emission nebulae in urban skies.

Introducing The World’s First Filter Warranty and Repair Service

All filters in the new STC Astro Urban Sky series are covered with the world’s first filter warranty and repair service, giving all customers peace of mind when investing in their astrophotography future.

I am confident that users will love these new products and that the results will speak for themselves.”
