Lunt Solar Systems has recently upgraded this telescope with a new <0.4Å etalon (standard), delivering even higher contrast and finer solar detail than previous versions. All orders will ship with this latest, improved configuration—no action needed.
- New-generation <0.4Å etalon delivers higher contrast and finer solar surface detail than previous versions
- Lightweight grab-and-go design weighs under 3 lbs for effortless solar observing anywhere
- A smooth 1.25-inch dual-speed focuser for sharp visual observing and easier solar imaging
- H-alpha solar filters reveal stunning prominences, filaments, active regions, and chromospheric texture in real-time
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 B1200 blocking filter provides safe visual observing and entry-level solar imaging capability right out of the box.
This upgraded configuration also features a smooth dual-speed focuser for more precise focusing during both visual observing and solar imaging sessions—making it easier than ever to dial in razor-sharp views of the Sun’s constantly changing activity. 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!
