NGC 4394 (2014)

Nice dataset other than the slight cut off on the right. Very obvious bar on this one. There is a spiral of dust that comes in from the top and goes all the way to the center clockwise but it’s hard to see unless you zoom in closely. The arms are wound tightly enough that they’ve run into one another. Almost makes it look like a one armed galaxy.

This galaxy was imaged as part of a study (Proposal 10515) on its neighbor, M85, which is a very nice elliptical shell galaxy. This is slightly weird, because that study had to do with the star clusters in M85. I wouldn’t guess that you’d want to include NGC 4394 in any of them. Nonetheless, I am grateful it happened.

The chip gap was filled with older WFPC2 data in the center. Near the edges where that didn’t reach, it was interpolated.
