Lunt LS50THa + LS50C double stack H-alpha solar telescope, B600 PT

The LS50THa is Lunt's most popular dedicated hydrogen-alpha telescope. Its internal etalon is pressure-tuned (Doppler True), shifting the bandpass smoothly and uniformly across the field so features can be scanned through the H-alpha line. An integrated clamshell base takes a Vixen dovetail, and the LS50C front filter adds double stacking.

Double stack

The LS50C compact double-stack filter threads onto the front of the LS50THa in seconds and places a second, tilt-tuned 0.4 Å etalon in series with the internal pressure-tuned etalon, narrowing the combined bandpass to about 0.35 Å for higher-contrast surface detail.

Safety

Always use the telescope with its Lunt blocking filter in place; it is a dedicated solar instrument in H-alpha configuration.
