Baader Planetarium Narrowband H-Alpha Filter 7nm, 65x65x3mm Square (without Cell)

Where astrophotography meets innovation, the Baader Planetarium Narrowband H-Alpha Filter 7nm, 65x65x3mm Square (without Cell) stands out. This high-quality, durable filter is centered on the 656.3nm wavelength, passing the narrow 7nm bandwidth, making it an exceptional choice for full-frame CCD and CMOS imaging sensors on a variety of optical systems.

Designed to work seamlessly with telescopes of all configurations and apertures, this filter performs optimally in a range from a super-fast f/2.8 to a more moderate f/10. Each filter is individually planeoptically polished, featuring a dielectric anti-reflection coating and IR blocking. This ensures the filter uniformly passes the maximum amount of bandwidth possible, virtually eliminating halos, reflections, and ghosting for a clear, crisp image every time.

One of the standout features of this innovative filter is its ability to completely reject light pollution and block longer interfering wavelengths. This enables even the faintest deep-sky objects to be imaged, regardless of the user's location, and with shorter exposure times compared to other filters.

Offered as a 65x65mm square unmounted option, this filter is perfect for custom applications and imaging rigs. Please note, this filter is intended solely for deep-sky astroimaging with CCD systems, and should never be used for direct solar viewing or solar photography, as it can cause permanent injury to your eye and equipment.

In the world of astrophotography, the Baader Planetarium Narrowband H-Alpha Filter 7nm, 65x65x3mm Square (without Cell) is a game-changer, designed to help you capture the beauty of the night sky in all its glory.
