- Compact and travel-friendly 50mm doublet refractor to take solar observing anywhere
- Dedicated Hydrogen-Alpha for detailed and safe views of solar prominences, flares, and filaments
- Featuring a 1.25-inch dual-speed R&P focuser allows smooth, precise solar focusing
- Precision pressure tuning etalons allows fine adjustment for changing solar activity
- Optional double-stack front-mounted filter available for ultra-narrow <0.4Å (sold separately)
Lunt 50mm H-alpha: The Ultimate Grab-and-Go Solar Telescope!
The Lunt LS50THa 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 <0.6Å bandpass, delivering dramatically improved solar contrast, darker backgrounds, and finer chromospheric detail compared to previous generations.
Built around a precision 50 mm doublet optical system optimized specifically for H-alpha observing, the LS50THa reveals stunning prominences, filaments, active regions, and solar surface texture in a portable package weighing around 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 dual-speed Rack & Pinion 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 LS50THa is an ideal grab-and-go solar telescope for beginners and experienced observers alike!
