So all was going along fine on the focus offsets until I hit Ha. I had already lengthened the exposure and total focus time but I still got this error - I'm guessing that it took to long to find Focus so it killed it? Not sure maybe some one knows. I see at the top of the script kill FM if more than 600 sec. Can I safely change it to 900 sec? I only need a few more minutes to complete the narrowband filters.
