Lunt 300mm Solar Telescope H-Alpha Pressure Tuned - LS300THa /B3400

Introducing the Lunt 300mm Solar Telescope H-Alpha Pressure Tuned – a dedicated F7 H-alpha telescope that pushes the boundaries of solar observation.

Lunt Solar's dedication to excellence attains new heights with the LS300T F7 Serrurier Truss design, a single or double-stacked research-grade telescope, surpassing all current solar instruments.

With an internal unobstructed etalon, it accomplishes a <0.65 angstrom bandpass, further refined to <0.45 angstrom in the available Double Stacked system.

Controlled by Single or Dual PC-USB computer systems, the True Doppler pressure tuning ensures precise adjustments.

The instrument features a 3.5-inch Feathertouch Focuser for optimal focusing control.

This model boasts the ability to capture full disc images, utilizing its expansive 24mm image size to unveil minute solar details. 

Whether single or double-stacked, the Lunt 300mm Solar Telescope H-Alpha Pressure Tuned offers unrivaled views of the entire sun through its progressive and advanced .45 angstrom filtering system, setting a new standard in solar telescope design.
