This image has taken a peculiar galaxy pair positioned in southwest region of Lynx. Both galaxies have sizes of a bit smaller than 2 arc minutes, north and south ones have numbers of NGC2444 and NGC2445, respectively. They have gravitational interaction each other, that has made NGC2444 about triangle shape. These two galaxies look like a butterfly.


NGC2537, IC2233
