SVBONY SV220 Dual-Band Nebula Filter, H-Alpha and O-III Narrowband Filter Bundle with T2 T Ring Adapter and T Adapter, 1.25 inches Metal Telescope Camera Adapter for Canon EOS Standard EF Lenses

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. SVBONY telescope camera adapter keeps the beautiful and interesting view of the telescope or microscope easily You can attach the camera to the telescope conveniently since using this SVBONY adapter combination You can also share with your friend or family through the camera screen;pictures and video which is available Usage Thread T adapter into T ring adapter;then thread the whole mount adapter into DSLR SLR to connect to telescope T2 t ring adapter Useful accessory allows you to attach camera to a telescope camera adapter;and other astrophotography accessories.

• 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
• Super easy to use;thread t adapter into t ring adapter;then thread the whole mount adapter into cameras to connect to telescope
• Universal t adapter fits all standard 1.25" diameter telescope microscope etc;t ring adapter is compatible for all standard 1.25" lenses of cameras;but not for SV13 spotting scope
