Worked with Focuser Max to explore the effects of being out of focus. Varied focus by +-5000 of origional position to see effects of being too out of focus (stars take on donut like shape). Fine tuning steps of 500 were taken in and out of focus to produce a sharper image.

Observation showing out of focus and in focus m39 are attatched to this log.
