The Svbony SV220 Duo-Band (H-Alpha & OIII) 3 nm Filter (2") is an ideal choice for astronomy enthusiasts who wish to take their deep-sky object imaging to the next level. This filter is particularly suitable for capturing hydrogen-alpha (H-Alpha) and oxygen-III (OIII) emission lines, thanks to its narrow passband of just 3 nm. The Svbony SV220 filter delivers outstanding performance with its high light transmission capability, ensuring clear and detailed images.
The extremely narrow passband allows for effective filtering of unwanted light sources, resulting in more contrast-rich and detailed observed objects. The Svbony SV220 Duo-Band filter is especially useful for reducing the disruptive effects of urban lights, making it an ideal choice for urban astronomers working with color cameras.
- Narrow passband: 3 nm
