I saw a video on YouTube where an astronomically inclined couple chronicled their adventures capturing the Owl Nebula. It’s an object I never tried observing, and I was intrigued. It’s quite an interesting nebula. I took eleven, 10-minute exposures. These are the longest exposures I’ve done successfully so far.
