SVBONY SV220 H-Alpha & OIII 2\" 7nm Duo-Band OSC Filter|Bortle 7 M8 & M20 NGC7000 For Sale

The SVBONY 7nm dual band filter is designed to drastically reduce the effect of light pollution, for emission nebulae, planetary nebulae and supernova remnants imaging.The 7nm bandwidth strongly isolates the nebulae\'s emissions into H-Alpha (red) and OIII (green-blue) from anything else, ensuring that the shooting astronomical object is pure enough, free from non-target spectral interference.Comparing to the traditional DSO photography plan “Monochrome camera + SHO filters + Filter wheel” and long single channel exposure time and post-processing, SV220 dual-band filter simplifies the tediousness and difficulties of photography and post-processing, gaining full color images with one-shot.The SV220 filter greatly reduces the effect of light pollution and moonlight, and makes it possibl

SVBONY SV220 H+O 7nm Duo-Band OSC Filter 2\" | For Deep Space Astrophotography🌌 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.Review with SV220Joseph 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.
