 There are a few nights a year which the seeing is extraordinary. This was one of them, the faintest star images are too small to show up in small 800 size images, so only larger images are seen here. Some refer to this group as the "Leo Quad", others the NGC3190 trio. Here we see a group of galaxies of amazing diversity. The centerpiece is NGC3190, an 11.7 magnitude SA peculiar spiral with a warped equatorial dust lane. Other galaxies are:

Upper left corner - NGC3185, a 13th magnitude SB spiral

Lower right of NGC3190 - NGC3193, a 12.1 magnitude E2 Elliptical

Lower left of NGC3190 - NGC3187, a 13.4 magnitude SB peculiar

There are hordes of very faint galaxies over the entire field. Please check out the largest image, there you will see resolved hundreds of faint almost stellar galaxies, especially near the barred spiral. They range in brightness from 17 for the brightest to 20 for the faint nearly stellar objects. I've also left the background slightly lighter than normal to show off the faint galaxies, and the nebulous bridge that seems to appear between some galaxies.
