LS80MT Premium Kit — 80mm Universal Day & Night Modular Telescope Flagship double-stack performance. FPL53 ED optics. The finest 80mm solar telescope Lunt makes.

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

The LS80MT Premium Kit is the finest 80mm solar telescope Lunt makes. Built around a premium FPL53 ED doublet objective with ion-assisted broadband AR coatings, it delivers exceptional contrast and colour correction for both solar and nighttime observation. The SFPT internal double-stack module places two independently pressure-tuned etalons in series, reducing combined system bandpass to <0.28Å — with dual independent Doppler True pressure tuners giving you complete control over bandpass optimisation.

Two pressure-tuned etalons working in series, each with its own tuning knob, each responding instantly to adjustment. The internal architecture maintains perfect optical alignment across the entire bandpass adjustment range. The result is sub-quarter-angstrom performance with the tuning flexibility that only dual pressure systems can provide.

What You'll See

At <0.28Å combined bandpass through 80mm of premium FPL53 ED optics, the chromosphere reveals structure that single-stack instruments at any aperture struggle to match. Plage boundaries resolve into sharp cellular networks. Filaments show multi-strand complexity with defined dark cores. Active regions display their full magnetic architecture — penumbral detail, light bridges, and small-scale evolution visible in real time. Prominences show internal threading and flow patterns from base to tip with a clarity that rewards patient observation.

By night, remove the H-alpha module and you have a premium 80mm f/7 FPL53 ED doublet refractor. The same glass that delivers exceptional solar contrast delivers the colour correction and contrast that serious observers demand for lunar, planetary, and deep-sky work. The same 2" dual-speed focuser. The same optical quality. A complete second telescope built into the one you already own.

The 7.2–21.5mm zoom eyepiece provides continuous magnification from full-disk context to tight active-region crops without changing glass — critical during sessions when conditions shift and you need to move between targets and magnifications without missing a moment.

Why This Package

The SFPT internal double-stack module is included. The internal double-stack architecture means both etalons benefit from pressure tuning rather than mechanical tilt, maintaining perfect optical alignment across the entire bandpass adjustment range. Two independent tuners give you separate control over each etalon for maximum flexibility in dialling in the exact bandpass position you want. The B1800 blocking filter provides 18mm of clear aperture for full-frame imaging capability. The 2" dual-speed focuser with 10:1 fine focus and ZWO EAF compatibility handles every accessory and imaging workflow you throw at it.

Great Multi-Function Watch
Color: Gray/Digital/Gray
I absolutely love my Timex Ironman watches. I have had many over a very long period of time. Wonderful set of functions for the price. Very affordable. Easy to use. Lasts a long time. Very easy to read in standard lighting. I like the Indiglo when needed, but do not use it too often. Absolutely love the ability to set a repeat timer to remind me to do something at a fixed interval, or to keep me on task for a fixed period of time. Great to be able to set three independent alarms. Potential to capture a huge number of splits with the stopwatch. I purchased this watch to replace a similar model with a dead battery. I have replaced batteries in the past, but it is quicker and easier to buy a replacement watch. I am saving my old watches for that day in the future when the Ironman model may no longer be available. I expect this will be my watch of choice for the rest of my life.
