Lunt LS60THaDS50 Hydrogen-Alpha Double Stack Solar Telescope

Now introducing the Lunt Solar Systems Double Stack LS60THaDS50 Hydrogen-Alpha Refractor Telescope. At its heart is a custom-made 60mm precision aligned singlet lens. The focal length of the Lunt LS60 double-stacked solar telescope is 500mm, providing a ~4.5mm image through a 6mm blocking filter. This model comes with the upgraded Starlight Instruments 2" Feather Touch Focuser with 10:1 reduction and 2.5" of travel.

Lunt Solar Systems LS60T Hydrogen-Alpha Double Stack Telescope Highlights

  • The Lunt LS60THaDS50 etalons will be matched at the factory.
  • The Lunt LS60THaDS will utilize a 60mm unobstructed internal etalon and a 50mm unobstructed, front mount etalon.
  • 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.
