Baader Planetarium 1.25" Round O-III f/2 Highspeed Filter with LPFC Mount

With the 1.25" Round O-III f/2 Highspeed Filter with LPFC Mount, you can unlock the full potential of your astrophotography. This high-quality, durable filter is specifically designed to meet the exacting demands of ultra-fast astrograph optics, including Hyperstar and RASA systems.

Unlike conventional narrowband filters, which often suffer from significant transmission loss due to the strong Central Wavelength (CWL) shift, this innovative filter features a CWL-preshift that perfectly aligns with f/2 to f/3 optics. This unique feature ensures optimal light transmission, even under the most challenging conditions.

The Full Width at Half Maximum (FWHM) of this filter is meticulously optimized. Despite the typical line broadening associated with fast optical trains, this filter delivers maximum contrast, enhancing the quality of your images.

This versatile filter truly shines when used with fast optics for high contrast emission nebulae imaging. When used between f/1.8 and f/3.5, it offers a dramatic improvement over standard sets of narrowband filters.

Crafted by Baader Planetarium, a reputable brand known for its high-quality optical products, this filter is an effective tool for any astrophotographer looking to capture stunning images in low light conditions or of fast-moving subjects. Its large filter size of 31.75mm allows for more light to pass through, making it an ideal choice for a variety of photography situations.

In summary, the 1.25" Round O-III f/2 Highspeed Filter with LPFC Mount is a high-speed, high-contrast, and high-quality solution for all your astrophotography needs.
