Another success story.

For those who have not yet availed themselves of this brilliant script, I can highly recommended it. [Not so] hidden away in the ACP Scripts folder (or accessible from the Web / Utilities page), it takes the hassle out of computing filter focus offsets, and does it beautifully. If you have gone to all of the trouble of setting up your focuser in FocusMax, and have your autofocus working reliably and repeatably, and have a filterwheel full of non-parfocal filters, this script is for you. It even creates and populates the FilterInfo.txt automatically at completion.

Thanks to Bob for making life just that little bit easier.
