The SVBONY SV220 7nm Dual Narrowband Filter captures SII and OIII lines with high precision; OD5 blocking and ≥88% transmission ensure vivid, low-noise nebula images even under light pollution; 44mm aperture supports full-frame imaging; M48×0.75mm thread offers wide compatibility; ideal for OSC cameras and true SHO color balance.
SVBONY SV220 OIII+SII 7nm Duo-Band Telescope Filter 2" |Bortle 8 M57 M27 NGC6960🌌 Uncover Faint Cosmic Details That Other Filters Miss
The SVBONY SV220 S+O 7nm Duo-Band Filter is your key to revealing the hidden textures of supernova remnants and nebulae. This 2" filter isolates the OIII (500.7nm) and SII (672nm) wavelengths in a single shot, cutting through light pollution to deliver crisp, detailed images from your backyard.
✨ Key Selling Points
Dual-Band OIII + SII Precision: Targets the emission lines of ionized oxygen and sulfur, perfect for capturing the faint, delicate structures of supernova remnants and nebula filaments that are invisible to broadband filters.
7nm Balanced Bandpass: Strikes the ideal balance between blocking light pollution and preserving fine detail. Eliminates background noise without losing subtle cosmic textures.
OD5 Deep Light Blocking: Blocks 99.999% of city glow, moonlight, and unwanted UV/IR light (300–1000nm range). Shoot stunning images from your backyard, no dark-sky trip needed.
High Transmittance Efficiency: ≥85% single-point transmission and ≥88% average peak transmission drastically reduce exposure times, lowering camera noise and making post-processing faster.
Universal 2" Fit: M48×0.75 thread, compatible with mainstream astronomical camera/telescope mounts.
🎯 Ideal Shooting Targets
Supernova Remnants: Veil Nebula, Cygnus Loop (reveals faint shockwave filaments and sulfur-rich textures)
Emission Nebulae: Orion Nebula, Carina Nebula (highlights the contrast between oxygen and sulfur layers)
Planetary Nebulae: Ring Nebula, Dumbbell Nebula (captures the outer sulfur shells and inner oxygen structures)
👤 Who It’s For
Deep-Space Enthusiasts: Perfect for those chasing supernova remnants and detailed nebula structures.
Urban/Suburban Astronomers: OD5 blocking crushes light pollution, so you can shoot from your backyard.
OSC & Monochrome Camera Users: Works with both one-shot-color and mono cameras for flexible imaging.
2" Equipment Owners: M48×0.75 thread, compatible with mainstream astronomical camera/telescope mounts.

Angel Eyes 30mmBy Lino Benz IC 1396 & Elephant's Trunk NebulaIC 1396 is a sparse open cluster associated with a large diffuse nebula, visible in the northern constellation of Cepheus. It is located in a stretch of the Milky Way partially obscured by dense dark nebulae, about 3,000 light-years away. Near the center of the nebula is the famous structure known as the Elephant's Trunk (vdB 142).
