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.
- Premium solar kit includes everything needed to start exploring the Sun in Hydrogen-alpha right out of the box (mount and camera not included)
- Package includes the Lunt Front Mounting Double Stack Filter for 40mm for ultra-narrow <0.29Å
- Front-mounted, tilt-tuned etalon reveals stunning prominences, filaments, and solar surface detail with impressive contrast
- Compact 40 mm grab-and-go design makes solar observing easy at home or on the road
LS40 Premium Kit - Lunt's Most Portable Dedicated Solar Telescope!
Now upgraded with Lunt’s new-generation etalons, every LS40THa Premium Kit is individually measured at 656.28nm using Lunt’s precision metrology equipment, ensuring every specification is verified—not estimated.
The LS40THa Premium Kit delivers some of the most impressive double-stack performance available in a compact 40mm solar telescope. The included front-mounted LS40FHa double-stack filter adds a second 0.4Å tilt-tuned etalon to the optical path, placing two matched etalons in series for an ultra-narrow combined system bandpass of <0.29Å. The result is incredibly rich chromospheric contrast, revealing solar surface detail, filaments, and prominences with a level of clarity rarely seen in this aperture class.
Despite its advanced performance, the LS40THa remains a true grab-and-go solar setup. Weighing just 2.6 lbs (1.2 kgs), the Premium Kit includes a smooth 10:1 dual-speed rack-and-pinion focuser, a versatile 7.2–21.5mm zoom eyepiece, and an extended 6 in (152.4 mm) Vixen dovetail for improved balance while using the double-stack filter. Whether you're traveling to an eclipse, observing from the backyard, or taking the scope into the field, this kit is built for solar observers who want to get the absolute most out of a portable 40mm hydrogen-alpha telescope.
Please note: Mounts and tripods shown are for display purposes only and are not included with Solar Ready packages.
What You'll See
At <0.29Å combined bandpass, the chromosphere reveals structure invisible at single-stack bandwidths. Plage boundaries sharpen into defined cellular networks. Filaments resolve into complex multi-strand structures with dark cores and distinct edges. Active regions display the full depth of their magnetic architecture. Prominences show internal threading and flow patterns from base to tip that single-stack instruments render as smooth, featureless arcs. The chromosphere stops being a texture and becomes a landscape.
The 7.2–21.5mm zoom eyepiece lets you scan full-disk context at 19x, then push in to 56x on active regions without changing glass — critical when conditions are changing and solar features are evolving faster than eyepiece swaps allow.
