Background info was impressive in the fact that this galaxy has a visible diameter similar to our own.
I was expecting this one to be bigger.
Appears to be more compact & massive than ours.
M77 is not quite face on (appears to be about 25 to 20 degrees tilted and may be a foreshortened barred spiral).
The impressive bit is the degree of resolution as most of the photos seen previously showed a bright central blob and a fuzzy outer set of arms with little structure.
No sign of an interacting companion, but there is a more distant spiral seen through the left quadrant of the outer spiral arm (shows as a small amber spiral).
Have a nice day: Ag
