This Solar Filter lets you use the Vaonis Vespera Digital Telescope to observe our closest star during the day. Mount the filter on the end of the optical arm to see and photograph sunspots. By taking multiple photos over the course of several days you can track part of the recurring 11-year cycle of sun spots, and also observe the sun's rotation. As with night-sky viewing and photography, the Vespera displays its image on the screen of your device, rather than through an optical eyepiece.
