Alpine Astronomical Baader Overview

Centered on the 656.3nm wavelength and passing the narrow 7nm bandwidth, the Alpine Astronomical Baader 7nm H-alpha Enforced-Narrowband CCD Imaging Filter is ideally suited for use with full-frame CCD and CMOS imaging sensors on optical systems, including telescopes of all configurations and apertures, ranging from a super-fast f/2.8 to a more moderate f/10.

Individually planeoptically polished, dielectric anti-reflection coated, and IR blocked, this filter uniformly passes the maximum amount of bandwidth possible to virtually eliminate halos, reflections, and ghosting. It also completely rejects light pollution and blocks longer interfering wavelengths, enabling even the faintest deep-sky objects to be imaged regardless of where the user is located, and with shorter exposure times versus other filters. It is offered here as a 65x65mm square unmounted option for custom applications and imaging rigs.

This filter is intended only for deep-sky astroimaging with CCD systems, and should never be used for direct solar viewing or solar photography as permanent injury to your eye and equipment can occur, up to and including blindness.
