Lunt Solar Systems is very excited to announce that we have been subcontracted by NASA and Goddard Space Flight Center to team with NASA Edge for the Live broadcast of the 2024 Total Solar Eclipse from Carbondale, Southern Illinois.
The event is open to the public and will be broadcast locally in the stadium and live via the web. Visit the Official NASA Edge website for more information on when and how you can join in the fun.
Lunt will be providing a Solar Lab that will house a 20” Heliostat feeding Sunlight to three @ 230mm Lunt Solar Telescopes fitted for Hydrogen-alpha, Calcium-k, and White Light. The images will be captured using RED monochrome cameras, processed in real time and broadcast live in 4k.

Here is a low-resolution image taken through the Lunt 230 Hydrogen-alpha scope in “single stack” mode (currently being tested).
The Lunt SunLab was built by Lunt Solar in 2017 for NASA for the “Great American Eclipse,” a highly-successful project that broadcast the eclipse in many digital formats in 2017 from Carbondale, Illinois.
The SunLab will be rebuilt at Lunt Solar Systems in Tucson and will be a mobile and robotic facility that will capture the daily activity of the Sun in 3 wavelengths of light: White Light, Calcium-k, and Hydrogen-alpha.
The SunLab is mounted on the back of a goose neck trailer and pulled by a Freightliner truck with an added office/facilities area. The trailer is equipped with auto-leveling jacks. The trailer can be maneuvered into position such that it aligns with north for accurate Solar tracking.
At the rear of the trailer there will be a 20″ Byres Heliostat with guided tracking on a fixed pier. This Heliostat is one-of-a-kind and will serve to direct the Sunlight into the SunLab. It will be protected in a custom roll-off observatory to maximize its view of the sky.
Inside the lab the Sun will fill the apertures of three @ 130mm Lunt Solar Telescopes. These telescopes will each be fitted with special filters:
Wavelength: 656.28nm (tuneable +/-1 Angstrom)*
Bandpass: <0.65A (<0.35A optional)*
Bandpass: 2.2 Angstroms (fixed)
Wavelength: Full Spectrum
Our H-alpha systems are remotely tuneable for capturing doppler shifting events and fine tuning to desired details. The tuning is instantaneous and can be calibrated to wavelength. There is no waiting on the time it takes to heat or cool and reach equilibrium. Our etalon systems are also barometrically sealed and not affected by changes in atmospheric conditions.
At the rear of the telescopes we will have a computerized XYZ stage that houses our RED 8k Helium Monochrome camera. The camera can be quickly moved between each telescope and brought to auto/manual/remote focus. Eventually we hope to be able to have all 3 RED cameras available at all 3 telescopes to capture all 3 wavelengths simultaneously. However, at the moment we have enough computing power to handle one 8k feed with processing, colorization, and storage, or for broadcast in near real time.
