Let your astrophotography ascend to new heights with the 31mm Round f/2 High-speed Narrowband Imaging H-alpha/OIII/SII Filter Set, expertly crafted by Baader Planetarium. This high-quality, durable, and innovative set of three filters is specifically designed to meet the exacting demands of ultra-fast astrograph optics, such as Hyperstar and RASA systems.Each filter in this setf the H-alpha, OIII, and SIIf is meticulously engineered to overcome the common challenges faced with conventional narrowband filters, which often suffer from significant transmission loss due to the CWL-shift. With a pre-shifted Center-wavelength (CWL) that harmonizes perfectly with f/2 to f/3 optics, these filters ensure that the full width half maximum (FWHM) is not only maintained but optimized for your imaging needs.The result is a filter set that, despite the line broadening typically associated with fast optical trains, delivers maximum contrast and detail. This makes it an effective tool for capturing the intricate structures of emission nebulae with unparalleled clarity. When used with optics ranging from f/1.8 to f/3.5, the filters exhibit a dramatic improvement in image quality, offering a triple signal-to-noise ratio compared to standard narrowband filters at f/2.Versatile and effective, this filter set is an essential addition for any astrophotographer looking to explore the cosmos with fast optics. Whether you're capturing the vibrant hues of a distant nebula or the subtle details of the sun's surface, the 31mm Round f/2 High-speed Narrowband Imaging H-alpha/OIII/SII Filter Set is designed to elevate your celestial photography to professional levels. Experience the universe through your lens with vivid colors and sharp contrasts, thanks to the innovative design and superior performance of these Baader Planetarium filters.
