Overcome the challenges of astrophotography with the Alpine Astronomical Baader 7nm H-alpha Enforced-Narrowband CCD Imaging Filter, a high-quality, innovative product from the reputable brand, Baader Planetarium. This durable filter is expertly centered on the 656.3nm wavelength, and exclusively passes the narrow 7nm bandwidth, making it an ideal accessory for full-frame CCD and CMOS imaging sensors on a wide range of optical systems.

Whether you're using a super-fast f/2.8 telescope or a more moderate f/2.10, this filter is designed to enhance your astrophotography experience. Each filter is individually planeoptically polished, treated with a dielectric anti-reflection coating, and IR blocked to ensure the highest quality images. This meticulous process allows the filter to pass the maximum amount of bandwidth possible, virtually eliminating halos, reflections, and ghosting in your images.

One of the standout features of this filter is its ability to reject light pollution and block longer interfering wavelengths. This allows even the faintest deep-sky objects to be imaged with clarity, regardless of your location or the level of ambient light. Moreover, this filter can help you achieve stunning results with shorter exposure times compared to other filters.

The Baader 7nm H-alpha Enforced-Narrowband CCD Imaging Filter is offered as a 50x50mm square unmounted option, making it a versatile choice for custom applications and imaging rigs. Whether you're a seasoned astrophotographer or a beginner in the field, this filter is a valuable addition to your equipment, designed to bring the wonders of the night sky into sharper focus.
