We observed the large and faint planetary nebula around IN Com in H α and N II light with a coronagraphic charge–coupled device on the Wise Observatory reflector, blocking the light from the central star. Our goal was to provide a second image of the object with which to confirm the features seen in the only published photograph from the paper by Longmore & Tritton reporting the discovery of this object. The nebula is extremely faint, but a combination of images totalling about one and a half hours of exposure shows it fairly well. A novel image processing algorithm has been applied to the noisy image in order to reveal faint extended details of the images. The algorithm is based on a non-linear self-adaptive filter applied to the wavelet transform of the image. The nebula is not round or elliptical, but shows a two-lobed or possibly three-lobed morphology, as well as a peculiar hole-like feature east of the central star. There is definite east–west and slightly less definite north–south asymmetry.
