On many objects I get very good Auto Focus results. For example here is an AF curve from the other night while imaging NGC 2903:
However, on some objects; particularly globular clusters or bright galaxies the AF process exhibits significantly distorted curves and fails to obtain a good focus. Here is an example from the same night while imaging M51:
Are there setting in the AF panel that I should adjust for different objects?
