Description

This image captures two galaxies in the northern constellation of Draco. Although they appear to be close to each other and similar in size, they are not. NGC 5963 (left) is 100,000 light years in diameter and 85 million light years away, while NGC 5965 (right) is much larger and more distant, at 240,000 light years in diameter and 160 million light years away.

Although both of these galaxies are spiral in structure, their appearances to us are vastly different. Bluish NGC 5963 is face-on to our apparent view. I like the diffuse nature of the faint blue spiral arms of this galaxy, which is classified as a low surface brightness galaxy.

NGC 5965, seen nearly edge-on, is yellowish in the core and middle regions, but bluish towards the outer edges. Note that the galaxy is not perfectly symmetric, with a longer arm on the left side. The end of this left arm is distorted slightly and appears slightly more bluish. This galaxy may be interacting with the small spiral galaxy seen just below it.

Shortly after I imaged these objects, Andrea Alessandrelli posted a request/challenge on Astrobin to obtain a "decent" image of them. If I had known of his request, I would have collected twice as much data in order to obtain a better quality image. These objects are difficult to process, particularly because of the diffuse arms of NGC 5963.
