We calculate the Hα luminosity of an outflow nebula resulting from propeller action in AE Aqr. While the outflow is bright enough to be detected as an extended source, 1 arcsec across, it is dominated by the point-spread function (PSF) wings of the central object. By subtracting a PSF model from HST PC data we rule out the extreme models of high mass-loss rate combined with narrow-angle outflow, but more precise measurements are required to explore the propeller parameter space further.
