Description

Shot on a cloudy night that turned out to be more clear than I hoped for, especially in the early hours. I shot the Owl nebula again as I didn't want to start a new project on this telescope and it's one of the few narrowband targets that are bright enough to see clearly in 1 sub. With every image, I am more amazed at the enormous difference in light-gathering capability of the Quattro after spending 1 year on an f/9.
