## Overview

The Svbony SV227 H-Alpha 5nm 2-inch filter is a precision-engineered narrow-band filter designed for monochrome astrophotography. It isolates the 656.3nm H-alpha emission line with a tight 5nm bandwidth and 90% light transmission, dramatically enhancing contrast and detail even under light-polluted skies. Waterproof and multi-coated, it fits seamlessly into any 2-inch telescope eyepiece, blocking infrared wavelengths to eliminate the need for additional IR filters—making it an essential tool for capturing stunning deep sky images.

## Description

The SV227 H-alpha filter works to filter out a large part of this light pollution. The clear focus range becomes wider when the optical density becomes larger. The filter is compatible with all 2 inch eyepieces. The peak transmittance is 90% and it’s a bit higher than before. The transmittance of the filter is up to 90%. Allowing 5nm bandwidth of light centered on a wavelength of 656.3nm to pass through. This H-Alpha filter also blocks infrared wavelengths from 700nm to 1000nm so you don't need a separate IR-Cut filter. After using this filter, you can take good quality images even under urban skies. Package Includes: 1x SVBNOY 2" H-Alpha 5nm 1x PP Material Plastic Box

## Features

- SV227 2" Narrow-Band Filter is specifically designed for use with monochrome cameras in astrophotography; it effectively isolates the emission lines of certain celestial objects; enhancing image detail and contrast to make features more pronounced
- SVBNOY H-Alpha 5nm 2" Filter blocks the transmission of contrast-killing light pollution wavelengths; improve contrast and detail
- Allowing 5nm bandwidth of light centered on a wavelength of 656.3nm to pass through; 90% transmission
- Astrophotography under a light-polluted night sky can be difficult; the solution is an H-alpha filter; the H-alpha cut-off filter works to filter out a large part of this light pollution
- 2 inch mounted; the filter can thread directly into the 2 inch barrel of your telescope eyepiece
- This H-Alpha filter also blocks infrared wavelengths from 700nm to 1000nm so you don't need a separate IR-Cut filter
