A couple of days ago, I experienced a strange issue in the middle of the night and put up a post here about it www.cloudynights.com/topic/699024-can-someone-take-a-look-at-my-logs-and-explain-what-went-wrong/ in which Wade kindly suggested PHD lost the guide star and focused on a pixel....reasonable assumption.
Last night, I was capturing more data and the issue repeated at almost the same part of the night. Guiding just goes nuts (see log and image) and when I try to recover the sequence, SGP refuses to plate solve. Don't think it's an issue with my mount which has been flawless since buying it, I have no snagging cables as they are all hooked into an Eagle and the mount is well balanced. Any ideas? Keen to do another imaging running tonight as it is clear but I'm not thinking the problem is going to replicate. Images to follow
