There is certainly a lot of unpacking to do in what is going on in M106, including...
1) It has an active black hole
2) It is a Seyfert galaxy
3) It has a Water Megamaser (but I hope, no Dr. Evil)
4) It's black hole is "sunken" into the its "donut hole" core and its bar appears to be at an angle to the spiral disk.
5) One side (the right) of the donut hole is raised, while the opposite one is not
6) There are tendrils of Halpha emissions that don't seem to lie flat in the spiral disc.... or do they?
7) The overall disc is bent in the middle and the outer part of the spiral arms on the RHS appear to create "mouse ears" that I am sure would make the galaxy appear like Mickey mouse if viewed face on. The outer arms appear pretty star-forming active too.
8) The stellar bulge creates a fog covering half of its visible radius.
Other than that, M106 is just a typical galactic spiral. At some point I am hoping to document the reasons for these characteristics at APRealSpace.com, but I have to admit, this is some time out still - there are a lot more basic concepts to cover first.
In the meantime, please visit the website for some technical, and even sometimes controversial, interpretations on galactic and other deep space goings on that might give you insights into your astrophotography. (I am getting closer to an official launch).
