The star HD 87643 is at the center of the extended nebula of dust and gas on the first image, obtained with the Wide Field Imager on the ESO/MPG 2.2-metre telescope on La Silla. The central panel is a zoom on the star obtained with NACO on ESO's VLT on Paranal. The last panel zooms further, showing an image obtained with the AMBER instrument making use of three telescopes of the VLTI. The field of view of this last panel is less than one pixel of the first image.
