Hα images of R Aqr from HST-WFC3 and VLT-SPHERE/ZIMPOL taken in October 2014. The left panel shows a 70′′ × 70′′ cutout of the WFC3 image of the strongly structured extended nebula. The middle panel is the 3.5′′×3.5′′ region of the WFC3 image of the central star indicated with the square in the left panel. The right panel is the central 3.2′′ × 3.2′′ area imaged with higher spatial resolution using SPHERE/ZIMPOL where also the two stars are marked with black dots. The color scale is 10 times enhanced for the central r < 0.7′′ region in the middle and the right panel. North is up and East to the left.
