Starshades are a leading technology to enable the direct detection andspectroscopic characterization of Earth-like exoplanets. In an effort toadvance starshade technology through system level demonstrations, theMcMath-Pierce Solar Telescope was adapted to enable the suppression ofastronomical sources with a starshade. The long baselines achievable with theheliostat provide measurements of starshade performance at a flight-likeFresnel number and resolution, aspects critical to the validation of opticalmodels. The heliostat has provided the opportunity to perform the firstastronomical observations with a starshade and has made science accessible in aunique parameter space, high contrast at moderate inner working angles. On-skyimages are valuable for developing the experience and tools needed to extractscience results from future starshade observations. We report on high contrastobservations of nearby stars provided by a starshade. We achieve 5.6e-7contrast at 30 arcseconds inner working angle on the star Vega and provide newphotometric constraints on background stars near Vega.
