This galaxy is larger than M94 nearby, and has much less surface brightness. The nucleus is tiny, almost stellar. There is no visual evidence of spiral structure. The halo is asymmetric with a clear edge on the S side, perhaps due to an invisible dust lane. Elsewhere the halo fades out to the sky background. The halo does not quite reach to the 9th magnitude star W of the galaxy. The sector of the halo on the N side seems fainter than the general halo illumination.
