| Description | At only 1.4x1 arc-minute, this is the smallest "Vera Rubin" galaxy I've captured to date. It is relatively bright and regular, and nearly face-on, which may have made it an acceptable target for Rubin's measurements. Structurally, at least at the resolution I can perceive through my telescope, it's not terribly inspiring, so I judged 30m of integration enough and moved on to the next target on my list. |
