SVBONY SV220 Dual-Band Nebula 1.25'' Filter, H-Alpha and O-III Narrowband Filter Bundle with SV705C Telescope Camera, Color Astronomy Camera with USB 3.0, Suitable for Astronomical Photography

SVBONY SV220 dual narrowband H-Alpha/O-III 7nm narrowband 1.25'' filter is specially designed for astrophotography in light-polluted environments, allowing imaging under bright artificial light pollution and moonlight conditions to capture color images without using multiple filter combinations. Images are most useful with single-use color cameras; can be used for imaging emission nebulae, planetary nebulae, and supernova remnants; high transmittance and sharp cutoff can greatly enhance contrast, showing the most detailed information about deep sky objects; designed to drastically cut off sodium Artificial light interference from vapor or mercury vapor street lights and other unwanted interference (e.g. sky glow); Dual Band Narrow Band Filters are not suitable for visual observation and are not designed for imaging or observing the sun. Please note that the SV220 is not well suited for fast telescopes, some users have reported that dual-band OSC filters paired with RASA can cause band shifts, thus clipping HA data.SV705C telescope camera is not only for planetary imaging; but also very powerful for EAA and lucky imaging; entry-level deep sky shooting; suitable for EAA enthusiast crowd. Based on the back-illuminated sensor and advanced pixel technology; the SV705C's full well charge can reach 38ke; the peak QE of SV705C can reach about 90%; you will get the better image quality.

• Reduce light pollution; SV220 telescope filter can greatly reduce the interference from natural light sources such as moonlight or artificial light pollution such as street lighting
• Astrophotographic;the filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; the filter allows high-contrast imaging even in areas with strong light pollution
• Improving contrast; an increase in contrast can be perceived as an increase in brightness; the filter makes the contrast of the nebula and sky background increase; not the nebula brighter
• SV705C telescope camera is not only for planetary imaging; but also very powerful for EAA and lucky imaging; entry-level deep sky shooting; suitable for EAA enthusiast crowd
• Compared with IMX485 sensor; IMX585 has 3 times the number of full well charges; and has a very high signal-to-noise ratio; which can improve users' shooting efficiency and capture outstanding celestial images
