Lunt 40mm H-alpha: The Ultimate Grab-and-Go Solar Telescope!
The Lunt LS40THa Dedicated H-Alpha Solar Telescope is the perfect entry into high-contrast solar observing—compact, lightweight, and incredibly fun to use. This updated version now features Lunt’s new-generation enhanced etalon system with an upgraded <0.4Å bandpass, delivering dramatically improved solar contrast, darker backgrounds, and finer chromospheric detail compared to previous generations.
Built around a precision 40 mm doublet optical system optimized specifically for H-alpha observing, the LS40THa reveals stunning prominences, filaments, active regions, and solar surface texture in a portable package weighing under 3 lbs (1.36 kg). The included B600 blocking filter provides safe visual observing and entry-level solar imaging capability right out of the box.
This upgraded configuration also features a smooth rack & pinion focuser for more precise focusing during both visual observing and solar imaging sessions—making the views of the Sun’s constantly changing activity easily accessible. Lightweight, easy to transport, and quick to set up, the LS40THa is an ideal grab-and-go solar telescope for beginners and experienced observers alike!
