After going back inside the observatory I prepared the D850 DSLR to image some more Herschel 400 Catalog galaxies. Mounted the D850 at prime focus, focused on the star Regulus, and locked the mirror.

2018 MST: High Precision ON.

2019 MST: StarLock ON.

Seeing was not very good this night, making accurate autoguiding a challenge. I was able to get these StarLock autoguided images (ISO 3200, 3, 2, and 5 minutes exposures, respectively).
