NGC3190 Galaxy Group

Galaxy Group in Leo

Uploaded 3/15/02

This is the deepest shot to date for me for this very interesting galaxy group in Leo. The Primary galaxy bottom center is NGC3190, a 12.1 magnitude type Sa spiral, which is 4.4x1.2 mins in size. Its brownish dust lanes extend to the very limits of the visible portion here. Very much contrasting, it the galaxy at the upper left, NGC3193 an Elliptical class object, with a magnitude of 11.8, and a size of 2 arcmins. It's tawny color is the result of large numbers of old yellow stars. The most interesting object is to the upper right NGC3187, a 13.4 magnitude spiral galaxy, with unusually long and low surface brightness arm extensions. You can see some small pink HII regions in this object, in the outer arms, which are very blue.

 Contrast enhanced image reveals the huge outer envelopes that seem to extend around each of the individual galaxies.
