Lunt Solar Double Stack Filter for Lunt 130mm & 152mm Telescopes

Double stacking provides a truly enhanced, high definition view of the Suns surface details. It lowers the bandpass of the system from less than 0.65 Angstroms to less than 0.45 Angstroms. This will significantly make the surface features on the Sun pop! The Lunt 130 mm and 152 mm can be internally double-stacked at the time of purchase or anytime thereafter and does not need to be returned to the factory for double-stacking.

Subsequently, add the DSII internal double stack module to make it a double stack unit later. This will make it more affordable to purchase our best solar telescope and still have room for upgrades. Once you upgrade your Lunt LS130MT with the LFPT internal double stack module, you will be able to see the finer details on the Sun that were not previously visible.

• Add an internal double-stacking module to a Lunt 130mm or 152mm telescope for a lowered bandpass of less than 0.5 Angstroms
• The LFPT includes a pressure tuner for true Doppler tuning
