Galaxies in Leo

Uploaded 4/14/2001

This galaxy trio is the first color image taken with my new ST-7E camera. The Primary galaxy bottom center is NGC3190, a 12.1 magnitude type Sa spiral, which is 4.4x1.2 mins in size. 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. 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. This object was not seen at all visually, and needed a good 5 second exposure to detect it with the CCD.
