Facts about M61 by Keith Turnecliff
mall telescopes show M61 as a faint oval-shaped patch with a bright core, while medium-sized and large telescopes reveal a very clear nucleus and a hint of the galaxy’s spiral arms. The spiral arms and details of the galaxy’s structure become much clearer in 10-inch and 12-inch telescopes.
