Lunt B1800d1 BlockingFilter in star-diagonal 1.25"

1. Dedicated Solar Observation: The Lunt B1800d1 is specifically engineered as a blocking filter, an essential component for any H-alpha solar telescope setup. It works in conjunction with an external H-alpha filter, ensuring safe and detailed views of the Sun.

2. Optimized Optical Path: With an 18mm filter diameter, this blocking filter provides a generous field of view, particularly beneficial for telescopes up to 1620mm focal length, helping to capture more of the solar disk or prominences.

3. Integrated Convenience: Housed within a 90° star diagonal, the filter offers a comfortable viewing angle, reducing neck strain during extended observational sessions. Its 1.25" compatibility ensures broad usability with many standard amateur astronomical setups.

4. Versatile Connectivity: Beyond visual use, the inclusion of a T2 thread allows for direct attachment of astronomical cameras, transforming your solar telescope into a powerful imaging instrument for capturing stunning solar details.

ABOUT THE LUNT B1800D1 BLOCKING FILTER

The Lunt B1800d1 Blocking Filter stands out by being integrated directly into a 90° star diagonal, offering a compact and convenient solution for observers. Unlike standalone blocking filters, this design streamlines your optical path, making setup quicker and more secure. Its 18mm aperture is optimally sized to handle telescopes with focal lengths up to 1620mm, providing a clear, unvignetted view of the Sun when paired with an appropriate H-alpha filter system. This filter is crucial for the safe and effective observation of solar phenomena, such as prominences, filaments, and sunspots, by isolating the H-alpha wavelength. The mechanical precision in its construction ensures a stable platform for both visual observation and astrophotography, thanks to its integrated T2 thread. Utilizing original accessories and spare parts, such as the correct H-alpha primary filter, is paramount to ensure the longevity and peak performance of your solar observing equipment.
