Lunt Blocking-Filter in extension tube

1. Dedicated H-alpha Filtering: This blocking filter is an essential component for safe and effective H-alpha solar observation. It works in conjunction with a primary H-alpha filter, ensuring only the narrow H-alpha wavelength reaches your eye or sensor, protecting against harmful solar radiation.

2. Versatile Integration: Housed within a convenient extension tube, this filter is compatible with a wide range of solar telescopes. Its design allows it to comfortably fit into both 1.25" and 2" telescope focusers, offering flexibility for various setups.

3. Optimized for Focal Lengths: With different clear aperture options (6mm, 12mm, 18mm), the filter can be optimally matched to telescopes with varying focal lengths, from 540mm up to 1620mm, guaranteeing excellent performance and image clarity for your specific instrument.

4. Eyepiece and Camera Ready: The integrated extension tube provides a standard 1.25" connection for eyepieces, facilitating visual observations. For astrophotography enthusiasts, a convenient T2 thread is included for direct camera attachment, making solar imaging straightforward.

ABOUT THE Lunt Blocking-Filter

The Lunt Blocking-Filter in extension tube represents a critical component for dedicated H-alpha solar observation. Unlike standard filters, this blocking filter is vital for the safe and efficient operation of an additional H-alpha filter system, ensuring only the narrow H-alpha wavelength is passed while blocking harmful light. It integrates seamlessly into your solar telescope setup, offering versatility with both 1.25" and 2" focuser compatibility. The clear aperture of the filter varies (6mm, 12mm, 18mm) to match different telescope focal lengths, from 540mm up to 1620mm, providing optimal performance and image brightness. Its straight extension tube design allows for easy integration, featuring a 1.25" connection for eyepieces and a T2 thread for camera attachment, making it suitable for both visual observation and solar imaging. Using original accessories and spare parts is recommended to prolonged the lifetime of your valuable solar observation equipment and maintain its peak performance.
