NGC247 is a large, but extraordinary dimmed galaxy positioned at 3 degrees south of beta Ceti forming the tail of Cetus. The galaxy has a major axis of about 20 arc minutes and 9.7 in magnitude, you might be needed good conditioned night sky to appreciate the galaxy through a medium-sized telescopes over 6-inch in aperture. NGC247 has a visual figure stretched in north south direction, with a very small and dimmed central nucleus but no spiral structures at all. At 4.5 degrees south of the galaxy, you can find a bright and splendid spiral galaxy of NGC253. This bright galaxy is attracted considerable attention rather than NGC247. But please challenge to find out this minor galaxy in autumnal night under high atmospheric transparency.
