- The 7nm dual band filter is designed to drastically reduce the effect of light pollution; high transmission and sharp cut-off greatly enhance the contrast and bring out the most detailed information when imaging emission nebulae; planetary nebulae; and supernovae remnants; the 7nm bandwidth means it strongly isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue)
- No need to travel through mountains and rivers; you can enjoy the fun of deep sky photography anytime and anywhere in urban areas; the dual-band filter helps astronomy enthusiasts to perform deep sky photography in urban areas with serious light pollution or under a full moon
- Lower the threshold for making astronomical works; the dual-band filter makes it possible to simplify and decrease the difficulty and cumbersomeness of post-processing for users
- Compared with traditional black-and-white deep sky photography; additional accessories and complex post-processing are required; dual-band filter can achieve a single exposure to capture large full-color images
- An ideal filter for use with one-shot color (OSC); CMOS cameras; and astronomical telescopes whose focal ratio is not less than F5
