Lunt Solar Systems LS80THa Pressure Tuned H-alpha Telescope

Now introducing the Lunt Solar Systems LS80/Ha H-Alpha Telescope! The perfect telescope for the intermediate solar observer. Want something more than your current 40mm set up but don't want to full tilt on your budget? This is the scope series for you!

But there's more than just a pretty view... You can achieve coarse focus adjustment with a slide tube, and then fine adjustments to focus are accomplished via the included dual-speed Crayford style focuser with 10:1 reduction. Its clam shell mount is compatible with most tripods and mounting holes are all part of the Lunt Solar Telescope System.... Right down to the stylized white pearl paint with anodized black trim and included foam lined hard case!

The LS80 Ha Telescope PT is a precision aligned ED refractor with a fully un-obstructed 80mm optical aperture. This package provides a significant step up into the Intermediary category of Daytime Solar Observing, Maintaining the most advanced technology of Doppler True Tuning for fine adjustment of the center wavelength, allowing research of the Sun’s disk and surface details at increased image scale. Prominences, flares, super granulation, filaments, and active regions will be observed.

The LS80THa package is fully upgradeable with several options including the NEW evolutionary Dual Internal Stack Etalon System (DSII). The DSII eliminates the need for an external double stack etalon reducing cost and eliminating obstructions. The system is 100% un-obstructed. The band pass is reduced to <0.5 Angstroms. See the Sun's weather in stunning high definition.

Lunt Solar Systems creates their line of h-alpha solar telescopes in Tuscon, Arizona. They have have put together a group of experienced solar enthusiasts who are looking forward to energizing the hobby with a continued commitment to advancing technologies, pride in quality, and the highest level of customer care. These are names you'll recognize, including Andrew Lunt with 20 years of optical design, Markus Ludes with his extensive knowledge of telescope design, Manny Serrano as a design engineer and Brian Stevens assembling, repairing and troubleshooting etalon systems. And newly designed etalon systems are what it's all about.... Some of their new products will range from an entry level 50mm etalon filter through to a 160mm Lunt Solar Telescope System using different components... One that's less thermally sensitive and far less prone to de-contacting.

Great Solar H-a telescope
Several months ago I purchased my Lunt 80mm HaPT/BF1200 Telescope. I am very happy with what can offer me this jewel. With the ZAO-16 the entire view of the sun is brilliant, crisp and contrasty, full of amount details on the surface and the prominences and flares are also able to seeing at same time thanks to the PT. The pressure tune works fine, smoothly and can keep the pressure perfectly even a month. It's also a great telescope for solar imagen. The telescope comes well protected on the carrying case and both the TV sol-searcher also Lunt zoom eyepiece works perfectly.

Secondly, OPT as usual from them made a perfect job, given perfect selling support. Many thanks Jason and Craig.

Outstanding solar telescope
I had a PST Solar scope, but just wasn't satisfied due to its "sweet spot" issues and the focuser. I liked it for portability and price, however.

After reading various online reviews, especially by Stephen Ramsden, interacting on line with other owners of H Alpha telescopes, talking to OPT and Rikki at Lunt, I decided that this Lunt 80 with pressure tuning and 1200 blocking filter and Crayford focuser was what I wanted. It was actually in stock at OPT, so I ordered it and had it in a week (shipping time to Ohio).

It is very well made, gives superior views of the Sun, sweet spot issues are negligible. I needed a more sturdy mount than the one I used with the PST, and ordered the Celestron CG-4, which works very well for this telescope.

Other members at my local astronomy club were all very impressed by it, and the majority opinion was that I would never need to double stack it.

It is still light enough that, with the mount, I can carry it from the garage to driveway for immediate viewing. I use it primarily for visual, but it's good for photography, too.

Attached photos, taken with modestly priced ZWO cameras, show some good results.
