Baader Planetarium 1.25" Round H-alpha f/2 Highspeed Filter with LPFC Mount

Make your astrophotography stand out with the 1.25" Round H-alpha f/2 Highspeed Filter with LPFC Mount. This high-speed narrowband filter is meticulously designed to meet the intricate requirements of ultra-fast astrograph optics, specifically tailored for Hyperstar and RASA systems.

Unlike conventional narrowband filters, which often result in significant transmission loss due to the strong Central Wavelength (CWL) shift, this filter boasts a CWL-preshift that perfectly aligns with f/2 to f/3 optics. This feature ensures that even in extreme cases, the CWL does not shift out of the Full Width at Half Maximum (FWHM), thereby maintaining optimal image quality.

The FWHM of this filter is expertly optimized to deliver maximum contrast, even with the typical line broadening associated with fast optical trains. This makes it an ideal choice for those seeking to capture high-contrast emission nebulae imaging.

For the first time, this filter enables the effective use of fast optics in astrophotography. When used between f/1.8 and f/3.5, it shows a dramatic improvement over regular sets of narrowband filters. Enhance your astrophotography experience with the 1.25" Round H-alpha f/2 Highspeed Filter with LPFC Mount, designed to deliver superior performance and unparalleled image quality.
