Lunt Solar Universal Ha Solar Telescope

The conversion is designed to be straightforward and takes only a few minutes. You simply remove the solar-specific components, such as the etalon and blocking filter, to reveal the standard APO refractor configuration for nighttime viewing.

The 130mm aperture provides significant light-gathering power, allowing you to resolve fine details on the sun's surface. You will be able to clearly observe complex prominences, filaments, and active regions with high contrast thanks to the pressure-tuning system.

Yes, the FPL51 triplet ED optical system is specifically engineered to eliminate chromatic aberration. This makes it an excellent choice for capturing sharp, color-accurate images of deep-sky objects when configured for nighttime use.

Pressure tuning allows for a more precise adjustment of the etalon's central wavelength by changing the air pressure inside the chamber. This provides a more uniform image across the entire field of view and offers better contrast compared to traditional tilt-tuning methods.

At 25 pounds, this is a substantial instrument. You will need a sturdy equatorial or alt-azimuth mount capable of handling the weight of the telescope plus your camera or eyepiece accessories to ensure stable, vibration-free viewing.

The B1800 blocking filter is an essential safety component for solar observation. It narrows the bandwidth of the light reaching your eye or camera, ensuring that only the specific H-alpha wavelength is visible while blocking harmful radiation.
