Lunt 152mm Doppler True Solar Telescope - B1200

Lunt 152mm Doppler True Solar Telescope B1200

The LS152THa from Lunt Solar Systems is a 6-inch dedicated Hydrogen-alpha solar telescope designed to deliver outstanding solar observation with a bandpass of <0.65 Angstrom.

True Doppler Tuning

The telescope’s True Doppler Tuning (Pressure Tuning) enables shifts toward and away from the observer, adding a three-dimensional effect to solar viewing. While prominences are only slightly affected due to their position at the edge of the solar disk, filaments and active regions on the Sun’s surface respond noticeably. Observing a filament near the center of the Sun, the user can Doppler shift from the filament’s base to its tip, effectively tracing the filament’s structure as it moves toward and away from you. This provides enhanced visual observation, imaging capability, and serves as a valuable research tool for dedicated hobbyists. The pressure tuning system adds a significant degree of precision, ensuring accurate tuning of the desired solar features.

Blocking Filter Options

All Lunt Solar telescopes require a blocking filter for safe and optimal use. Selecting the correct filter depends on your application:

• B1200: Ideal for visual use.

• No Blocking Filter Warning: Only select this option if you already own a Lunt Solar Systems blocking filter. Remember, all Lunt H-alpha telescopes require a blocking filter for safe operation.

Lunt LS152THa Solar Telescope Overview

Currently the largest solar telescope in the Lunt lineup, the LS152THa provides an impressive balance of resolution and performance. Its 100% unobstructed system delivers high-quality visuals at both low and high magnifications. Utilizing advanced high-contrast coatings along with the Doppler True Pressure Tuning system, users can enjoy sharp, crisp images for high-magnification observation and advanced digital imaging.

True Doppler Tuning – Detailed

The True Doppler Tuning feature allows precise shifts toward and away from the observer, introducing a 3D-like viewing experience. While prominences at the Sun’s edge remain largely unaffected, filaments and active regions in the solar center respond to these adjustments. Observers can trace filaments from base to tip, enhancing both visual observation and imaging, making this an exceptional tool for hobbyists and researchers. The precision of the pressure tuning system allows for meticulous adjustment of targeted solar features.

Optional Modules and Nighttime Conversion

The LS152THa can be equipped with an interchangeable Calcium K (CaK) module for exploring multiple wavelengths using the same telescope platform. Additionally, the telescope can be converted for nighttime viewing with a dedicated backing plate and focuser kit, making it a versatile instrument for both solar and celestial observation.
