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.

Extremely comfortable, leather sole. Hard to find a style.
Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue, Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue
Totally worth the price. This type of style is very hard to find, my husband had another pair a few years ago that he was never able to replace. These fit his wide feet and are very comfortable. The elastic at the ankle is not too tight. So glad I was able to find him a replacement. We bought the blue in a size 12. Love the fact that they are washable.

Very comfortable Slippers. Great buy!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
I bought these to replace a pair of slippers that I have had for years that are very similar to the slippers I bought, but I had worn a hole in the leather on mine, so I had to find something new and similar. These slippers are worth the money they are very comfortable, and I am sure they will last for years. They are a little tight around the ankle cuff but they are still new and I am sure they will wear in a little more when I start wearing them more.

Great slippers but disappointing quality.
Size: 7.5-8.5 Women/6-7 Men, Color: Ash, Size: 7.5-8.5 Women/6-7 Men, Color: Ash
Extremely comfortable, attractive slippers but the stitching came loose on both leather trim areas almost immediately. I tried to sew/glue down the stitching (as seen in photo) but it kept unraveling. Disappointing as these slippers are great in every other way (though they do run a bit big...I wear a 9 but ended up with a 7.5-8.5 which fits with a bit of room to spare even with thick socks). I just hope they hold up after my latest attempt to stop the thread from pulling out any more as I do really love wearing them. Perhaps I just got a bum pair?

Very thin and comfortable. Wash well.
Very thin sock if that is what you are looking for. They stay up and wash well. There is a toe seam but you can position it out of the way
