🌌 Capture Vibrant Nebula Color Without Multiple Filters The SVBONY SV220 H+O 7nm Duo-Band Filter is your all-in-one solution for stunning deep-space imaging. This 2" filter locks onto the two most important nebula wavelengths in a single shot, letting you cut through light pollution and capture crisp, colorful details from your backyard. ✨ Key Selling Points Dual-Band Precision: Simultaneously isolates H-Alpha (656.3nm, red) and OIII (500.7nm, blue-green) wavelengths, so you get both colors of emission nebulae in one exposure—no need to swap filters. 7nm Balanced Bandpass: Strikes the perfect balance between blocking light pollution and preserving fine details. It eliminates background noise without losing the subtle textures of nebulae. OD5+ Deep Blocking: Blocks 99.999% of city glow, moonlight, and unwanted UV/IR light (300-1000nm range). Shoot from your backyard, no dark-sky trip required. High Transmittance Efficiency: 85% single-point transmission and 94% peak transmission drastically reduce exposure times, lowering noise on entry-level cameras and making stacking faster. Universal 2" Fit: Featuring a large 44mm aperture and M48*0.75 standard thread, it is compatible with mid-to-high-end wide field-of-view/high-resolution astrophotography equipment. 🎯 Ideal Shooting Targets Emission Nebulae: Orion Nebula, Lagoon Nebula, Eagle Nebula, and Carina Nebula (vibrant red and blue-green details pop in one shot) Planetary Nebulae: Ring Nebula, Dumbbell Nebula (highlights the contrast between hydrogen and oxygen layers) Supernova Remnants: Veil Nebula (reveals faint filament structures in both H-Alpha and OIII) 👤 Who It’s For Beginner Astro Photographers: All-in-one design keeps things simple, no need to manage multiple filters. Urban/Suburban Imagers: OD5+ blocking crushes light pollution, so you can shoot from your backyard. OSC Camera Users: Perfect for one-shot-color cameras, capturing both key nebula wavelengths in a single frame. 2" Equipment Owners: Featuring a large 44mm aperture and M48*0.75 standard thread, it is compatible with mid-to-high-end wide field-of-view/high-resolution astrophotography equipment. Ready to simplify your deep-space imaging and get vibrant, noise-free shots with less effort? This filter turns your OSC camera into a nebula-capturing powerhouse. |
 | Joseph Milazzo I purchased the svbony sv220 dual narrow band filter. I am very pleased. The eagle nebula was only 20 -2 minute subs. The crescent was 47 2 minute subs. Scope was sv503ed 102 and ASI533 cam. |
