NGC 3184 is a spiral galaxy in the constellation Ursa Major, approximately 40M light-years distant. Notice that the spiral arms are not distinct and separate, but have inter-arm stars and gas. The blue hues are contributed by bright, young blue stars while the red knots and streaks are generated by ionize hydrogen gas.
Nearby bright stars (1 is obvious in the image) and the intervening Integrated Flux Nebula (IFN) make processing of the image difficult. They impart streaks, noise, and glare/flare to the images.
