Package includes: SV260 2" Multi-Bandpass Star Filter for Wide-Field Astrophotography SV260 multi-bandpass filter is a 5-bandpass broadband pass light pollution filter. Equipped with OD3 cut-off depth and over 90% peak transmittance, the filter is designed to isolate 6-level light pollution and make light wave transmission maximum to enhance deep-sky details and improve the visibility of deep-sky objects. OD3 cut-off depth filters out the unnecessary light produced by artificial lighting including mercury vapor lamps, both high & low-pressure sodium vapor lights, and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow). More than 90% peak transmittance reduces the light loss and delivers images of broadband-emitting objects, such as galaxies, reflection nebulae, and globular clusters, with minimal color cast. SV226 M54-M48 Filter Drawer 2'' Filter Holder for Astrophotography SV226 2-Inch Filter Drawer offers a reliable solution for filter storage and management. Featuring dual magnets for secure fixation and a locking mechanism to prevent light leaks, it ensures filters are safely placed. With two 2-inch drawers, it's ideal for quick filter swaps, boosting efficiency for astronomy enthusiasts. Crafted with durable CNC precision machining, the 20mm thickness ensures clear imaging. It includes an M54-M48 adapter ring, compatible with full-frame cameras. |
🌌 Capture Vibrant Wide-Field Deep-Space Images, Even From Suburban Skies The SVBONY SV260 2" Multi-Broadband Pass Filter is designed for wide-field astrophotographers who want to cut through light pollution while preserving the natural colors of galaxies, nebulae, and star clusters. It balances high transmittance of key cosmic wavelengths with targeted blocking of common urban light sources, making it perfect for large-sensor, wide-field imaging setups. ✨ Key Selling Points Multi-Broadband Precision: Transmits all critical nebula and galaxy wavelengths with ≥90% peak transmittance (H-Alpha, OIII, SII, H-Beta) and ≥85% average transmittance. The red transmission curve in the spectral graph aligns perfectly with both artificial and constellation emission lines. Targeted Light Pollution Blocking: Features OD2-3 cut-off depth, blocking sodium and mercury streetlight emissions (e.g., 546nm, 577nm, 589nm) and unwanted UV/IR light (T≤1% @ 350–400nm & 720–1100nm). 2" Full-Frame Coverage: 44mm clear aperture eliminates vignetting on full-frame sensors, and the M48*0.75 thread fits 99% of mainstream 2" telescopes, filter wheels, and wide-field cameras. High Optical Quality: Surface quality 60/40 and parallelism λ/2 ensure sharp, distortion-free images across the entire field of view. 🎯 Ideal Shooting Targets Galaxies: Andromeda Galaxy, Pinwheel Galaxy (preserves natural spiral arm details and color balance) Reflection Nebulae: Witch Head Nebula, Iris Nebula (captures delicate blue/white reflected starlight) Globular & Open Star Clusters: Pleiades, Omega Centauri (resolves individual stars while suppressing background glow) Large Emission Nebulae: Orion Nebula, Lagoon Nebula (retains vivid H-Alpha and OIII colors) 👤 Who It’s For Wide-Field Astrophotographers: Perfect for 2" full-frame cameras and wide-angle telescopes. Suburban & Urban Observers: Reduces streetlight and moonlight interference for clearer images from non-dark-sky locations. Galaxy & Cluster Enthusiasts: Preserves natural color and detail for large, faint deep-sky objects. Casual to Intermediate Imagers: Easy to use with no complex filter swapping, great for wide-field surveys and time-lapse projects. Ready to turn your wide-field imaging sessions into stunning, color-accurate deep-space photos? The SV260 filter lets you capture the beauty of the cosmos without leaving your backyard. |
