NGC 3190 and Hickson 44

Hickson 44, a group of interacting galaxies in the constellation Leo, lies approximately 80 million light years from Earth. In the background are many fainter galaxies which are much more distant.
 
NGC 3190, the largest galaxy just right of center, is a spiral galaxy seen almost edge on. Its characteristic dust lane is its most prominent feature. To it's lower left is NGC 3187, a barred spiral galaxy, and to the upper left is NGC 3185, another barred spiral with a smaller bar. To the right is NGC 3193, an elliptical galaxy.
 
This galaxy group was quite a challenge from our light polluted skies. Additionally, the waning moon chased us across the sky each night. We collected 169 6-minute Luminance subexposures (just under 17 hours) and another 11 hours of RGB. Processed in Pixinsight and Photoshop.
