Abstract
We present ISO observations of A58 and A78. Both objects are suspected to have undergone late He flashes ('born-again' nebulae). With ISOCAM we have been able to obtain data of much higher spatial resolution ov er the wavelength range 4.5-18 mu m than has been possible in the past . In order to extract full information from our data we have developed a method to eliminate residual variations in the dark field. The resu lts for A58 and A78 are compared with literature data and with A30 - t he most prominent 'born-again' planetary nebula (PN).
