Lunt Internal Double Stack: Push Your Solar Observing Further!
Upgrade your Lunt Solar Systems Universal Modular Telescope with the SFPT internal double-stack module and unlock dramatically higher solar contrast and finer surface detail. Featuring Lunt’s new-generation precision etalon technology, the SFPT reduces the system bandpass from 0.45Å single-stack performance down to an ultra-high-contrast <0.28Å—revealing darker filaments, sharper active regions, richer surface texture, and more intricate prominences.
Designed specifically for Lunt 80 mm and 100 mm Universal telescopes, the SFPT installs internally without changing the telescope’s size, balance, or nighttime observing capability. For maximum tuning precision, the SFPT features dual independent Doppler True tuning controls—one for each etalon—allowing you to fine-tune solar contrast and dial in the best possible view for changing solar conditions and observing targets.
Specifications
- Model: SFPT — Internal Double Stack Module
- Compatible: LS80MT Universal Telescope | LS100MT Universal Telescope
- Single Stack Bandpass: 0.45Å (telescope internal etalon)
- Etalon Bandpass: 0.35Å — individually verified
- DS Combined Bandpass: <0.28Å — SFPT (0.35Å) + MT internal PT (0.45Å)
- Tuning: Dual independent Doppler True Barometric pressure tuning
- Installation: Customer-installed — no factory return required
- Night Sky Use: No impact — internal module does not affect night configuration
