Description and Details: Using the ML Astro SHG700 spectroheliograph, I acquired several scans of the Sun, around the 7065A wavelength. By continuum subtraction and further processing, the helium signal could be revealed, like the much stronger 10830 and the D3 (5875.6) which also requires processing. To the best of my knowledge, this is the first full disk image of the Sun in this wavelength.
