Askar E1+E2 2-inch Ultra Duo-narrowband Filter Set Professional Astrophotography Tool for Deep-sky Imaging
Description:
- The Ultra E Filter, as its name suggests, boasts "Ultra" halo control capabilities. During its development, we implemented special design optimizations, resulting in a unique filter with one passband at 3nm and another outside the 3nm range.
- With the Ultra E Filter, you can shoot high-quality deep-sky images even in areas affected by urban light pollution, atmospheric airglow, or other light sources. The narrower bandwidth and high transmission significantly enhance image contrast, making it easier to reveal subtle details of celestial objects that are typically difficult to shoot.
- Beyond the traditional Hα+OIII duo-narrowband filter, the Ultra E filter also introduces an SII+OIII filter.
- We designate the Hα+OIII filter as E1 and the SII+OII filter as E2 filter. Together, they form the Ultra E Filter Set, offering color camera users a novel way to achieve results similar to those taken with monochrome cameras and triple narrowband filters - without the need for additional equipment. This opens up new possibilities for astrophotographers to enjoy even more astronomical wonders.
- With exceptional halo control and innovative imaging solutions, the Ultra E Filter helps you explore the deeper beauty of the Universe.
Package Included:
- 1 x E1 Filter
- 1 x E2 Filter
