HARPS-N Solar Telescope
Description of the HARPS-N Solar Telescope
We are operating a small solar telescope at the TNG/HARPS-N. This telescope, coupled to the HARPS-N spectrograph, takes spectra of the Sun every 5 minutes for several hours each clear day.
Above is a photograph of the solar telescope with its side panels removed showing the optics (a 3" lens feeding an integrating sphere that is fiber-coupled to the HARPS-N calibration unit along with guide cameras to keep the telescope guiding the Sun) and the electronics including an amateur mount, surge suppression and power supplies to drive the cameras, mount and USB controls.
The first year of solar radial velocities.
