Featuring 7nm H-Alpha and O-III bands, it effectively blocks artificial light sources such as street lamps and moonlight, enhancing contrast and detail in nebula imaging. Its durable aluminum construction with multi-coating ensures high transmittance and waterproof reliability, making it an essential tool for deep-sky photographers seeking sharp, high-contrast images in challenging urban environments. ## Description SVBONY dual narrowband H-Alpha/O-III 7nm narrowband filters are specially designed for astrophotography in light-polluted environments, allowing imaging under bright artificial light interference and moonlight conditions to capture color images without using multiple filter combinations. Images are most useful with single-use color cameras; can be used for imaging emission nebulae, planetary nebulae, and supernova remnants; high transmittance and sharp cutoff can greatly enhance contrast, showing the most detailed information about deep sky objects; designed to drastically cut off sodium Artificial light interference from vapor or mercury vapor street lights and other unwanted interference (e.g. sky glow); Dual Band Narrow Band Filters are not suitable for visual observation and are not designed for imaging or observing the sun. Please note that the SV220 is not well suited for fast telescopes, some users have reported that dual-band OSC filters paired with RASA can cause band shifts, thus clipping HA data. Review: Looks professionally made Review: Bueno, pero no Perfecto. - Por el precio, es un buen filtro, especialmente para principiantes o quienes no buscan fotografías 100% perfectas. Produce halos, especialmente en las estrellas más brillantes. Pero es un buen producto para comenzar en el aprendizaje y uso de fotografía de doble banda estrecha. ## Features - Capture Purer Nebula Light: SV220 2" Dual-Band Filter allows high transmission of OIII (500.7nm) and H-Alpha (656.3nm) nebula emission lines, while effectively blocking artificial light interference and skyglow - Improve Image Quality: Featuring over 94% transmission and superior Out-of-band light rejection, SV220 nebula filter delivers a significant boost in image contrast and detail for deep-sky astrophotography - Capture the Cosmos Downtown; use SVBONY SV220 telescope filter to enable deep-sky photography in light-polluted cities or under a full moon - Crafted for Astrophotography: SV220 2" astrophotography filter is designed for color CMOS, CCD, and digital cameras, significantly reducing the difficulty and hassle of post-processing - Specification: Anodized aluminum frame; Waterproof optical glass; net weight: 50g; Thread specification: M48*0.75 - Suitable astronomical telescope: SVBONY SV220 narrowband filter cannot be used with smart telescopes or astronomical telescopes with a focal ratio of f/4 or less ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BRCYF29T | | Best Sellers Rank | #711,980 in Electronics ( See Top 100 in Electronics ) #33 in Telescope Filters | | Box Contents | 1 X Plastic packaging box, 1 X SVBONY SV220 2" Dual narrow-band filter, 1 X Spectrum diagram | | Brand | SVBONY | | Brand Name | SVBONY | | Coating Description | Multi Coating | | Compatible Devices | Cameras with astrophotography capabilities | | Customer Reviews | 4.8 out of 5 stars 98 Reviews | | Enclosure Material | Aluminum Optical Glass | | Item Dimensions L x W | 5.1L x 5.1W Centimeters | | Item Type Name | filter | | Item Weight Unit of Measure | 30 Grams | | Manufacturer | SVBONY | | Manufacturer Part Number | FW9172B | | Material | Aluminum Optical Glass | | Media Type | ProductImage | | Model Name | SV220 | | Model Number | FW9172 | | Number of Pieces | 1 | | Photo Filter Effect Type | Enhancing | | Photo Filter Size | 50.8 Millimeters | | Photo Filter Thread Size | 48 Millimetres | | Screen Size Unit of Measure | 2 Inches | | Unit Count | 1 Count | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** SVBONY - **Material:** Aluminium - **Photo Filter Thread Size:** 50.8 Millimetres - **Coating Description:** Multi Coating - **Photo Filter Effect Type:** Enhancing ## Images ![SVBONY SV220 Telescope Filter, 2 inches Dual-Band Nebula Filter, H-Alpha and O-III Narrowband Filter for One-Shot Color Cameras, Light Pollution Filter for Astrophotography - Image 1](https://m.media-amazon.com/images/I/51TOKCxbePL.jpg) ![SVBONY SV220 Telescope Filter, 2 inches Dual-Band Nebula Filter, H-Alpha and O-III Narrowband Filter for One-Shot Color Cameras, Light Pollution Filter for Astrophotography - Image 2](https://m.media-amazon.com/images/I/815bfJB-5xL.jpg) ![SVBONY SV220 Telescope Filter, 2 inches Dual-Band Nebula Filter, H-Alpha and O-III Narrowband Filter for One-Shot Color Cameras, Light Pollution Filter for Astrophotography - Image 3](https://m.media-amazon.com/images/I/71rQOPy2D8L.jpg) ![SVBONY SV220 Telescope Filter, 2 inches Dual-Band Nebula Filter, H-Alpha and O-III Narrowband Filter for One-Shot Color Cameras, Light Pollution Filter for Astrophotography - Image 4](https://m.media-amazon.com/images/I/81j62xdBYLL.jpg) ![SVBONY SV220 Telescope Filter, 2 inches Dual-Band Nebula Filter, H-Alpha and O-III Narrowband Filter for One-Shot Color Cameras, Light Pollution Filter for Astrophotography - Image 5](https://m.media-amazon.com/images/I/71uedPc1ulL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Looks professionally made *by G***M on 31 January 2024* ### ⭐⭐⭐⭐ Bueno, pero no Perfecto. *by J***N on 23 October 2023* Por el precio, es un buen filtro, especialmente para principiantes o quienes no buscan fotografías 100% perfectas.
