Product Overview

The Baader 7.5nm Solar Continuum Filter acts as a narrowband photosphere filter, ideal for solar observations in white light. This filter enhances sharpness by focusing on the 540nm wavelength, where lens systems deliver optimal image quality. It provides greater contrast, even on achromatic and apochromatic telescopes, by blocking other wavelengths and reducing the effect of atmospheric turbulence.

Benefits of the 7.5nm Solar Continuum Filter

This filter is designed to deliver maximum contrast and sharpness in solar imaging, making it suitable for various telescopes and camera types. Compared to previous models, the 7.5nm bandpass allows for enhanced contrast without the need for filter stacking. Its optimized design works exceptionally well with CMOS sensors, offering features like blackened edges and Reflex-Blocker™ coatings to prevent halos and reflections.

Important Usage Information

Note: This filter should only be used with additional protective filtering, such as the Baader Herschel Prism or AstroSolar Safety Film, to ensure safe solar observation.

Included with Baader Cool Ceramic Herschel Prism Mk II

The Baader 7.5nm Solar Continuum Filter is also part of the Baader Cool Ceramic Herschel Prism Mk II package, making it a valuable addition to solar observing kits.
