Product Description

Now equipped with Lunt’s newer, higher-performing etalons, these telescopes deliver a tighter ≤0.35Å FWHM per etalon, improved from the previous ~0.55Å design. In double-stack configuration, system bandwidth drops to approximately 0.22Å for even greater contrast and finer solar surface detail.

The LS80 Imaging Kit upgrades two critical areas for observers ready to capture the Sun at 80mm aperture. The B1800 blocking filter provides a generous 18mm clear aperture that fully illuminates full-frame sensors without vignetting. The complete four-eyepiece flat-field set covers every visual magnification you will use, from full-disk surveys to tight crops on active regions.

The same 80mm f/7 doublet objective. The same Doppler True pressure-tuned etalon delivering <0.65Å bandpass. Now with the optical clearance and eyepiece range to match the resolving power of 80mm aperture.

What You'll See

Everything the LS80 reveals, now with the magnification range to explore it all. The 8mm eyepiece (70x) pushes in tight on active regions when seeing cooperates, resolving fine magnetic structure and small-scale brightenings. The 12mm (47x) is your workhorse for surface features and prominence detail. The 16mm (35x) provides the sweet spot between magnification and field of view for extended observing sessions. The 19mm (29x) pulls back for full-disk views and limb surveys. All four eyepieces share consistent 60° apparent fields and the same 0.1% AR coatings used on Lunt etalons, minimizing ghost reflections in the narrow-band optical path. Switch between eyepieces and the view stays clean at every magnification.

Why This Package

The B1800 is the blocking filter that serious solar imagers choose for 80mm systems. Its 18mm clear aperture ensures your full-frame sensor sees the complete, unvignetted image circle. Combined with the 2" focuser's ZWO EAF compatibility for motorized focus control, this package is ready for dedicated imaging sessions. For visual observers, four dedicated eyepieces mean you always have the right magnification without compromise. Solar conditions change constantly: seeing fluctuates, active regions evolve, prominences erupt. Having 29x through 70x at your fingertips means you are always observing at the right power for what is happening on the Sun.
