Description

This is the second processed image from my first two nights with the new Takahashi FSQ-106EDX4 scope. I chose to spend a little bit of time on five different scenes of Messier galaxies. My joke that I keep repeating is that this was not a Messier Marathon, but more of a Messier Mini-Meander.

I really enjoy looking at galaxy fields, particularly when accompanied by annotations. And it was doubly fun to acquire and prepare this field. M101 was the very first image that I made 6 years ago with my first dedicated astrophotography system, so making this one was a bit nostalgic for me.

In the annotated image you can see the tremendous number of background galaxies. When I have the time I will investigate them further and maybe update the annotations with red-shift data where available.
