Summary edit
| Description |
Another (pre?)planetary nebula. Not the most visually appealing, but hey, it's bipolar and I haven't seen it before. The ACS' HRC seems to take lovely pictures of super bright objects, but when it comes to darker ones it gets pretty noisy. I guess the culprit would be exposure time. F814W ended up being especially noisy. These data were collected as part of proposal 9463: Are OH/IR stars the youngest post-AGB stars?
