Object Data: NGC 3190 is at the centre of a fascinating group of gravitationally interacting galaxies, catalogued as Hickson 44, in the constellation of Leo. At lower left is NGC 3193, a face-on eliptical fairly devoid of detail, appearing more as a mysterious glow. Moving clockwise to above centre we find NGC 3187, an edge-on barred spiral with fantastically warped outer arms, giving it a surreal quality. Further clockwise on the right side we have NGC 3185, a face-on barred spiral that looks reassuringly normal in comparison. Back to the centre, NGC 3190 is a spiral type galaxy seen almost edge-on, but with arms clearly distorted through gravitational interaction with its neighbours. Also visible faintly at centre-right is MAC 1017+2146, and at upper-right, MAC 1017+2147.
