Double stacking provides a truly enhanced, high definition view of the Sun’s surface details. It lowers the bandpass of the system from < 0.7 Angstroms to < 0.5 Angstroms, which really makes the surface “pop”! The Lunt LS152THa can be internally double-stacked at the time of purchase or anytime thereafter. The LS152THa does not need to be returned to the factory for double-stacking.
Buy risk-free: When it’s time to trade up you’ll get the most value for your used gear.
