SVBONY SV220 Telescope Filter, 7nm Dual-Band Nebula Filter, H-Alpha and O-III Narrowband Filter Bundle with SV226 M54 Telescope Filter Drawer, Dual Magnet Holders for Deep Sky Astrophotography

The SV220 dual-band filter is designed for astrophotography of emission nebulae, planetary nebulae and supernova remnants. The high transmission and sharp cut-off greatly enhances the contrast of image and brings out the most detailed information of those deep-sky objects. The 7nm dual-band filter allows OIII (500.7nm) and H-Alpha (656.3nm) nebula emission lines to be highly transparent, strongly isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue), and drastically reduces the effect of light pollution. SVBONY SV226 M54 Telescope Filter Drawer adopts a dual magnet design to provide higher stability; the dual filter holder allows you to change filters easily; compatible with 2-inch filters, M54-M48 adapter ring to connect to different cameras; CNC one-piece molding, higher precision!

• Dual magnets: the SVBONY SV226 M54 Filter Drawer features a dual magnet design; providing double stability to ensure your filters stay securely in place; This innovative design helps prevent accidental drops
• Designed for Deep Sky Astrophotography, M54 Filter Drawer can be adapted to full-frame camera; ensuring a wide, vignetting-free field of view; fast Filters Swapping for full-frame astrophotography
• Two filter holders: with this Filter Drawer; you can swap filters quickly and easily; significantly improving your workflow; No more wasting time during critical moments—just smooth transitions between different filters
• 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
