Lunt B600d1 Blocking-Filter in star-diagonal 1.25"

1. Essential Safety Component: The B600d1 is a crucial blocking filter designed to work in conjunction with dedicated Lunt H-alpha filter systems. It safely removes unwanted wavelengths of light, allowing only a very narrow bandpass of the H-alpha spectrum to reach the eye or camera, making solar observation safe and effective. Without a blocking filter, solar observation through an H-alpha system is unsafe.

2. Integrated Star Diagonal: This model uniquely integrates the blocking filter into a 90° star-diagonal, providing a comfortable viewing angle for extended solar observing sessions. Its 1.25" barrel fits most standard astronomical focusers, offering wide compatibility.

3. Optimized for Specific Focal Lengths: With a blocking diameter of 6mm, the B600d1 is specifically optimized for telescopes with a focal length of up to 540mm. This ensures proper illumination and performance across the field of view for suitable optical setups.

4. Versatile Connectivity: Equipped with a 1.25" eyepiece holder and a T2 thread, this blocking filter diagonal offers flexibility. Observers can easily switch between visual observation with 1.25" eyepieces and solar imaging by attaching a camera directly via the T2 thread, enhancing its utility for both casual observers and astrophotographers.

ABOUT THE Lunt B600d1 Blocking-Filter

The Lunt B600d1 Blocking-Filter stands apart by integrating its critical solar blocking function directly into a convenient 1.25" star-diagonal. Unlike standalone blocking filters, this design streamlines your setup, offering a compact and user-friendly solution for safe H-alpha solar observation. It is an indispensable component that works in tandem with a front-mounted or internal H-alpha filter, ensuring that only the specific H-alpha wavelength is passed through, while all other dangerous wavelengths are safely blocked. This precise mechanical design and optical alignment ensure superior performance and safety. The 6mm filter diameter is specifically tuned for telescopes up to 540mm focal length, making it an ideal choice for a range of smaller refractors and dedicated H-alpha telescopes. Its fixed 90° angle provides comfortable viewing, whether you're performing visual observations or engaging in solar imaging via the integrated T2 thread. Always ensure you use original Lunt accessories and spare parts to maintain the product's integrity, optical performance, and to prolong its lifetime.
