Lunt LS300THa Double Stack with B3400: High-performance solar telescope
The Lunt LS300THa Double Stack with B3400 is the ultimate in solar astronomy technology, designed for enthusiasts and demanding professionals. With its colossal 300 mm aperture, its Double Stack system enabling a bandwidth reduced to < 0.45 Å, and its B3400 blocking filter, this dedicated solar telescope redefines the standards of solar observation and imaging. It is a unique instrument, designed to reveal the finest details and most dynamic solar phenomena with unrivalled precision.
Revolutionary technology to explore the Sun
The LS300THa is based on an unobstructed internal Fabry-Perot etalon system, which exploits the wave-like properties of light to isolate the H-alpha line (656.28 nm). In Double Stack mode, two internal standards reduce the bandwidth to < 0.45 Å, providing spectacular contrast. This setting highlights fascinating solar structures, such as :
- Solar protuberances : Huge plasma arches projected into space.
- Dark filaments : Suspended rivers of magnetized plasma.
- Chromospheric granulation : Fine texture and dynamics of the solar surface.
- Active regions : Intense magnetic zones where sunspots form.
Incomparable technical features
- Opening : 300 mm, offering exceptional brightness and resolution for capturing details invisible with smaller instruments.
- Focal length : 2128 mm (f/7), ideal for combining high resolution with a balanced field of view.
- Double Stack: Bandwidth reduced to < 0.45 Å for maximum contrast.
- B3400 blocking filter : With its generous 34 mm diameter, it guarantees a vignetting-free field of view, even with large-format sensors.
- True Doppler Pressure Tuner electronic system : Precise control via PC or USB for optimum customization of settings.
- Focuser Feather Touch 3.5 inch : The legendary Starlight Instruments focuser offers unrivalled precision with a fine 10:1 reduction.
- Robust, elegant construction: Carefully machined aluminum tube designed to withstand intensive use.
