M106 is a spiral galaxy located in the Canes Venatici constellation.

This galaxy was surprisingly easy to photograph from the city. Normally face-on or nearly face-on galaxies are quite dim compared to the local light pollution. However M106 seems to be quite bright even though its apparent magnitude is only listed as 9.1. It also frames well in the MN190 telescope and the reddish coloration works well with the spectral response of the STF-8300M camera.

Besides having a well defined core, this galaxy also has a fairly large halo surrounding it. The halo barely shows up in this image. But it is at least faintly visible and I think that if I were to photograph it from a proper dark site it could be more prominent.

Just above M106 and a bit to the left is another galaxy, NGC 4248. And for those with a keen eye, above NGC 4248 are two more galaxies NGC4231 (left) and NGC 4232 (right). Besides these three, there are a few more small faint galaxies in this image as well.
