M33 was one of the first objects I photographed three years ago. Due to its brightness, I took advantage of a moonless evening to capture it.
Session Analysis
The session was overall quite unspectacular, but with slightly below-average seeing, which is clearly visible in the guiding performance here. It remained relatively stable throughout the evening, ranging between 0.5″ and 0.8″. I had reduced the automated refocusing from the previous 1°C to 0.75°C. I think I will stick with this value.
