First-Light Observations Using the Multi-Band Lucky Imaging Cameras at SONG

About fifty years ago, in the middle of the 20th century, lucky imaging cameras became popular for making beautiful images of planets in the Solar System. Nowadays, lucky imaging is a well-established observing strategy that is used to produce high cadence, sharp images of stars in visible wavelengths. During each observing run, from the hundreds of images taken every night the sharpest ones are selected, shifted, and added to produce a high signal-to-noise and high spatial resolution combined image, that would not be possible to obtain by means of ground-based long-exposure observations. One of such system that simultaneously operates in both red and visible wavelengths, has been mounted at the 1m Hertzsprung SONG (Stellar Observations Network Group) Telescope on Tenerife. Here we present how the lucky imaging system operates at SONG, along with our first-light observations.
