The main event last Thursday in the IUSB Observatory was an attempted exoplanet detection with students Emilee Edmonds, Phillip Derrickson, and Liz Turpin — data still to be analyzed. But I stuck around afterward for a while and took this photo of M57, the Ring Nebula. It’s a 120-second exposure with active guiding, after adjusting the focus with a Bahtinov mask. I’m pretty happy with it.
