Sorry to say that the last release does not fix the guiding calibration issue for my AP400GTO (a recent answer of the ZWO team said it was fixed for the Celestron mounts).
As mention some weeks ago, it is exactly the same as @matt s reported.
I had, many weeks ago, sent logs to ZWO team for that issue, and did it again this night.
Just for the record,I tried the latest release tonight on my Ipad. Everything went right (PA, goto, manual moves of the mount..) except the guiding calibration process: the stars continue to move on the screen when the soft does the different steps and backlash tests. The conclusion is a "time out to settle... " message, The soft pretends guiding but of course does not.
I was told that AP uses the Meade protocols, so I don't understant why this issue could not be fixed.
I just have now to go back to the 1.6 version (and restore the original firmware on the ASIAR...) which works fine, but on a small Iphone and without the sky atlas feature.
To bad!
I really hope that this issue will be fixed one day!
