Orion has discontinued the X-tra Narrow Band SII 1.25" Filter, and we are out of stock. Here is a link to the 1.25" Narrowband Imaging Filters we carry at High Point. Hopefully, you can find a proper replacement in this selection. If we can be of further assistance, please don't hesitate to call us at 1-800-266-9590 or send an email, and we will be happy to help you. Thank you!



Orion X-tra Narrowband SII 1.25" Filter 05579






  • The Orion S-II filter passes light at 672.4nm wavelength with a bandpass of 7nm.


  • Orion S-II Extra Narrowband 1.25" Filter is made from high-grade glass, featuring vacuum-deposited dichroic interference coatings and antireflection coatings.


  • The S-II Extra Narrowband 1.25" Filter by Orion is housed in an anodized aluminum cell.


  • The S-II Filter can be used for tricolor CCD astrophotography use with O-III and H-alpha extra-narrowband imaging filters.







The Orion SII Extra Narrowband 1.25" Filter allows you to go beyond RGB imaging and capture your favorite nebulas in a revealing new light, no matter how polluted your skies may be. Want to capture dramatic Hubble-like CCD images of emission nebulas from the heart of the city of under a full moon? Imaging with S-II, O-III, and H-alpha extra-narrowband filters allows you to do so. These specialized filters transmit only the specific wavelengths of light that are important in emission nebula, while blocking out all other light. Whether artificial or natural, from street lamps, the Moon, you name it, the Orion OIII will block it all. Using the Orion S-II Extra Narrowband 1.25" Filter results in high-contrast tricolor images from even grossly light-polluted skies making your observing experience, just about anywhere a delight!






The S-II filter passes light at 672.4nm wavelength (the Sulfur-II line in the deep red end of visual spectrum) with a bandpass of 7nm and a very high 90% transmission. The S-II filter complements the Orion H-alpha and Oxygen-III extra-narrowband filters. Together, the three filters allow advanced tricolor imaging of emission nebulas with StarShoot Deep Space Monochrome CCD Imaging Camera or other monochrome CCD cameras.





Made from high-grade glass, these 1.25" filters feature vacuum-deposited dichroic interference coatings and antireflection coatings. No refocusing is needed when switching among these filters as all three are parfocal. Housed in an anodized aluminum cell, each filter is threaded to fit a standard CCD camera 1.25" nosepiece or the Orion Multiple Filter Wheel.






Images taken with extra-narrowband filters typically look much different from those acquired using standard "true color" (RGB) methods. Rather then rendering an image in "natural" color, the extra-narrowband filters provide a visual representation of the elemental makeup of a nebula. This highlights with assigned colors the areas where the light obtains primarily from either Hydrogen-alpha, Oxygen-III, or Sulfur-II ions. This tactic is used by astronomers from many of the nebula pictures taken with the Hubble Space Telescope. While gorgeous, the extra-narrowband "false color" images reveal much about the chemical composition of the nebula and its various features.





Adding the Orion S-II Extra-Narrowband filter to your imaging collection will help you go beyond the RGB imaging and will help capture your favorite nebulas in a totally new light, no matter how polluted your skies may be!
