Unmatched Solar Photosphere Imaging

The Photosphere filter is a valuable tool for solar photosphere imaging, providing a narrowband design with a center wavelength (CWL) of 540nm and a bandwidth of 7.5nm. This filter is designed to be used with a Baader film or Herschel wedge to effectively reduce sunlight before imaging, ensuring optimal performance and safety. By capturing the best detail and contrast of the sun's photosphere, the Photosphere 7.5nm filter allows for impressive solar granulation and detailed sunspot features. Benefits:

• captures the best detail and contrast of the sun's photosphere
• impressive solar granulation and detailed sunspot features
• use with Baader film or Herschel wedge for optimal performance

Optimal Setup and Specifications

To ensure optimal performance and protection against dust particles on the camera glass, we recommend setting up the Photosphere filter on a T-mount. This not only guarantees the best results but also adds an extra layer of protection. The filter features a 1.25-inch size with a thread of M28.5*0.6, and its frame thickness is a total of 7.5mm, with a filter lens thickness of 2.5mm. With a transmittance of approximately 97% and a blocking depth of OD4, this filter is designed to provide exceptional performance. Specifications:
