This Optolong LRGB/H-Alpha filter set combines everything you need for stunning planetary and deep-sky observations. In this set, you will get Optolong's Luminance, Red, Green, and Blue (LRGB) filters and a 7nm Hydrogen-Alpha filter.

All Optolong filters in this set are made with Schott glass that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength, or CWL. The filter cells are made of lightweight, strong metal and are CNC machined, sand-blasted, black anodized, and then laser engraved. The result is a super thin filter cell that will produce a clear aperture of 26mm.

Optolong LRGB Filter Set - The Optolong LRGB Filter Set comes with four filters, including Red, Green, Blue, and Luminance. They are designed for de-bayered monochrome CCD and CMOS cameras and work great for both planetary and deep-sky imaging. Like all Optolong filters that are designated as “CCD”, this filter set blocks infrared wavelengths from 700nm to 1100nm so you don't need a separate IR-Cut filter.

Optolong 7nm H-Alpha Filter - The Optolong H-Alpha 7nm is an extremely narrow emission-line filter that works by allowing a 7nm bandwidth of light, centered on the 656nm wavelength through, and blocking the transmission of contrast-killing light pollution wavelengths. Wavelengths that are responsible for natural light pollution, or skyglow, are drastically reduced, as is artificial light pollution caused by high and low-pressure sodium vapor and mercury vapor lights. The result is a high contrast image that reveals the H-alpha line in all its glory.
