  • The Lunt Solar Systems LS60THaDS50 Double-Stack 60mm H-Alpha Telescope is a custom designed 60mm singlet refractor with a focal length of 500mm.
  • The LS60THaDS50 model comes double-stacked with a 50mm external etalon from the factory so that you can be assured of the best possible resolution and contrast.
  • The Lunt Solar Systems LS60THaDS50 Hydrogen-Alpha Refractor Telescope includes a 6mm blocking filter that provides a ~4.5mm solar image, and a 2" Crayford focuser.
  • Use the Lunt double-stacked LS60THa in single stack mode for prominence viewing or in double-stack mode for surface detail!


Lunt LS60THaDS H-Alpha Double Stack Telescope

Now introducing the Lunt Solar Systems Double Stack LS60THaDS Hydrogen-Alpha Refractor Telescope. At its heart is the custom-made 60mm precision aligned singlet lens. The focal length of the Lunt LS60ThaDS solar telescope is 500mm, providing a ~4.5mm image through a 6mm blocking filter. Course focus adjustment can be achieved via a slide tube with fine adjustments to focus accomplished through the included dual-speed Crayford style focuser with 10:1 reduction.

Lunt Solar Systems LS60THaDS Hydrogen-Alpha Double Stack Telescope Highlights

  • The Lunt LS60THaDS will be double-stacked from the factory.
  • The Lunt LS60THaDS will utilize unobstructed etalons.
  • With two factory-matched etalons, you will have a versatile system that can be used single-stacked for prominence viewing, and double-stacked for observing surface detail of the Sun.
  • Single stack mode will achieve a bandpass of ~0.75.
  • Double stack mode will have a ~0.55 bandpass
As experienced solar observers know, it takes less than 1.0 angstrom to be able to see any detail and considerably less to see striking contrast - especially on the ever changing prominences. The reduction in bandpass from an estimated 0.8 Angstroms to 0.5 Angstroms seems to bring the Sun's surface to incredible life, but getting those spectacular results by double stacking are more difficult than they sound. Both etalons need to be brought on line (tuned) and both need to be tiltable so that all ghosts are eliminated. Ideally the transmission curves should overlap perfectly when on band to provide for the best possible resolution and contrast. These hurdles can be overcome by matching the etalons at the factory.

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.
