Now with new-generation etalons — every unit individually tested on Lunt's precision metrology equipment. Every specification is verified, not estimated.

The LS60MT Enhanced Kit upgrades the Standard with two targeted improvements for observers ready to capture the Sun. The B1200 blocking filter doubles the clear aperture to 12mm, providing the back-focus clearance and illumination circle that imaging sensors demand. The 7.2–21.5mm zoom eyepiece replaces the fixed 16mm, letting you frame full-disk views or push in tight on active regions without changing glass.

The same professional-grade 70mm FLP51 ED doublet optics. The same Doppler True pressure-tuned etalon at 0.45Å verified bandpass. The same day-to-night versatility. Now configured for the observer who wants to capture what they see.

What You'll See

Everything the LS60MT reveals at 0.45Å bandpass, now with the optical clearance to put it on a sensor. The B1200's 12mm clear aperture ensures the full image circle reaches your camera without vignetting at focal lengths up to 1,200mm. Visually, the zoom eyepiece transforms the observing experience. Scan the full disk at low power to survey prominence activity and filament structure, then twist to higher magnification and resolve individual features in real time. No eyepiece swaps, no refocusing, no missed moments of good seeing. Near-parfocal design keeps focus close across the zoom range.

Why This Package

If you are ready to start capturing the Sun — or if you simply want the convenience of a zoom eyepiece for visual observing — this kit delivers both. The B1200 is the blocking filter that serious solar imagers choose: 12mm of clear aperture means your sensor sees the full unvignetted image circle. The zoom eyepiece is a genuine game-changer for solar sessions. Conditions change, targets move, and active regions evolve. Continuous magnification adjustment without changing glass means you are always at the right power for what is happening on the Sun. And like all Lunt 60mm systems, the Enhanced is fully double-stack capable — add a DS module at any time to bring combined system bandpass to <0.28Å.
