## Description

desertcart.com : SVBONY SV220 Telescope Filter, 2" 7nm Dual-Band Nebula Filter for Deep Sky | H-Alpha & O-III Narrowband Filter, Reduce Stray Light, for One-Shot Color Camera, Telescope Accessories for Astrophotography : Electronics

Review: Great nebula filter - Great filter at a good price! Good results with my stock/unmodified canon DSLR. Still able to focus on bright stars using a bahtinov mask. Suppresses over exposed and bloated stars, minimizing the need for star reduction. Blocks almost all moon-glow, allowing more emission nebulae to be imaged during the full moon. Of course it's not suitable for reflection nebula and galaxies, since it only passes Ha and OIII.
Review: Very good dual band filter - Outstanding filter. Made a huge difference in my imaging. Because of 2" size, no notice of vignetting with ASI533MC Pro.

## 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
