M106 and Friends

About 22-25 million light-years away in the constellation Canes Venatici, you’ll find M106, a large spiral galaxy with a black hole in the center. There’s several other galaxies in this image, the most prominent of which is NGC 4217, which is about 60 million light-years away!

Last night I was able to spend a good amount of time imaging the region of galaxies around M 106. One plus to having a wide-field scope is you can see the cosmic neighborhood of just about any object. Here we've got M106 at the center of the image, and a generous handful of other galaxies appearing as well. The second most prominent galaxy just to the lower left of M106 is NGC 4217. The Small Galaxy just below M106 is NGC 4248, and the one further toward the bottom of the image is NGC 4220. Toward the top of the image, just to the right of center is NGC 4346, and the faint galaxy just left of center is NGC 4288, and the faint one in the top left, I believe is UGC 7408. And that's only the most prominent ones! There's dozens of other galaxies in this image that are small and faint, and hundreds more that are simply too faint to see or otherwise got lost in processing. Some day I do plan to add a longer focal length telescope to my arsenal so I can better capture these objects in more detail.
