Lunt Front Mount 40mm Double Stack Solar Filter - LS40FHa
Presenting the Lunt Front Mount 40mm Double Stack Solar Filter, known as the Lunt LS40FHa, stands as a precision-crafted 40 mm aperture etalon, seamlessly integrated for optimal performance on Lunt Dedicated 40 mm Telescopes, offering unobstructed solar views.
Specifically designed for compatibility with the Lunt 40mm Dedicated Hydrogen Alpha System, the Lunt LS40FHa Double Stack Unit introduces an additional layer of sophistication to solar observation, emphasizing the necessity of a Lunt Solar Systems Blocking Filter for safety compliance.
Benefiting from an estimated bandpass of <0.70 Angstrom, the LS40FHa Solar Filter excels in delivering high-contrast views of both the solar surface and its intricate edge details.
Notably, the potential for further enhancement arises with the option of double-stacking, where an additional etalon system can reduce the bandpass to ~<0.50 Angstrom, unlocking the capability for heightened resolution in both visual observation and imaging endeavors.
The safety-conscious approach is underlined with the mandatory requirement of the Lunt Solar Systems Blocking Filter, ensuring secure solar viewing practices.
As a result, the LS40FHa stands as a versatile and advanced solar filtering solution, offering astronomers the opportunity to explore the dynamic details of the sun with enhanced clarity and precision.
Features:
- 40mm Optical Aperture: The Lunt Front Mount 40mm Double Stack Solar Filter boasts a precise 40mm aperture, ensuring optimal solar observation and imaging capabilities for enhanced details on the solar surface.
- Non-Obstructed Design: With its non-obstructed design, this solar filter attaches directly to the objective of the Lunt 40mm Dedicated Ha Telescope, allowing unimpeded light collection for superior clarity in solar views.
- Double Stack Capability: Offering double-stack functionality, the filter achieves a bandpass of ~<0.5 Angstrom, providing increased resolution for detailed solar observations and imaging.
- Tilt Tuning: Tuning is facilitated through a tilt mechanism, allowing users to fine-tune the filter for optimal solar surface and edge detail observation.
- Unchanged Focal Length: The filter maintains an unchanged focal length of 400mm, ensuring consistency in magnification for both single and double-stack configurations.
- Aluminum Finished Hard Case: The solar filter comes with a protective aluminum finished hard case, featuring fitted foam to safeguard the filter during storage and transportation.
- Lightweight Construction: Weighing approximately 1 lb. (~0.4 kg), the filter's lightweight construction enhances the portability of the setup for convenient outdoor solar viewing sessions.
- Front-Mounted Configuration: Designed to be front-mounted, the filter simplifies attachment to the Lunt 40mm Dedicated Ha Telescope, streamlining the solar observation setup.
- Safety Emphasis: The filter emphasizes safety by requiring use with a Lunt Solar Systems Blocking Filter, ensuring secure solar viewing practices and safeguarding both equipment and observers.
