NGC 6438 and NGC 6438A are a pair of interacting galaxies in Octans, less than 5 degrees from the south celestial pole. NGC 6438 appears to be an elliptical galaxy, while NGC 6438A is distorted and may be a ring galaxy seen edge-on. NGC 6438 is visible in an 8" telescope as a small dot, but a 12" or larger is needed to see NGC 6438A.
