The Baader Fhaln-2 Narrowband CCD Filter Set Alpha 7nm OIII SII, with the SKU 2458384, is an exceptional offering for astrophotography enthusiasts seeking to capture stunning deep-sky images. This filter set includes two high-quality narrowband filters, specifically designed for capturing emitted light in the OIII (Oxygen III) and SII (Sulfur II) spectral lines.
The OIII filter, with a narrow bandwidth of 7nm, is optimized to isolate the OIII emission line, which is a common feature in nebulae such as the Orion Nebula and the Swan Nebula. This filter helps to reduce light pollution and increase contrast, leading to more detailed and vibrant images.
The SII filter, also with a 7nm bandwidth, is designed to isolate the SII emission line, which is often found in nebulae such as the Lagoon Nebula and the Eagle Nebula. This filter also helps to reduce light pollution and increase contrast, leading to more detailed and vibrant images.
The Baader Fhaln-2 filters are made from high-density Schott glass, which is known for its excellent optical quality and durability. The filters are also multi-coated to minimize internal reflections and improve transmission, ensuring that as much light as possible reaches your imaging sensor.
The filter set comes in a sturdy plastic case, making it easy to transport and store. Each filter has a thread size of 2" (51.6mm), making them compatible with most telescopes and imaging systems.
In summary, the Baader Fhaln-2 Narrowband CCD Filter Set Alpha 7nm OIII SII is a high-quality, professional-grade filter set that is perfect for capturing detailed and vibrant deep-sky images. With their narrow bandwidths, high-density glass construction, and multi-coating, these filters are sure to help you unlock the full potential of your astrophotography setup.
