Optolong 36mm Unmounted Filter Set with LRGB and 7nm H-Alpha Filters



This filter set gives you Optolong's Luminance, Red, Green, and Blue (LRGB) filters and a 7nm Hydrogen-Alpha filter. All filters have a 36mm aperture and come unmounted. With all of these fantastic filters, it's easy to see why they have become a favorite among amateur astronomers.



Each filter in the Optolong 36mm Unmounted Filter Set is 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. This filter set is designed to be used in color filter wheels that accept 31mm unmounted filters. It doesn't matter which way you drop them into the filter wheel. The filters are unmarked and either side can face up or down.



Optolong LRGB Filter Set - The Optolong LRGB Filter Set comes with four 36mm unmounted 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.
