Ken - One thing I discovered about the ASIAIR version of PhD guiding is that you have to set the guiding rate to 1X in TWO places - on the AP hand controller keypad (or on AP mount software if using that) and on the ASIAIR pull-out tab (it pulls out to the left from the right-side vertical control panel).  This ASIAIR pull-out tab is the same one you use to select your target and direct a GOTO.  The guiding rate needs to be set at 1X in both places or the guiding is all over the place.   Kevin

Hmm I wonder if there is something wrong with my setup. I use a 250 mm fl guide scope with an ASI 1290 cam as guidecam

Hi Kenneth

I've had very unpredictable guiding performance with AsiAir Pro until the latest version with multi star guiding. 

I haven't had too many chances to test it out but the guiding was very good when I did. Better then the best with the previous version. And seemingly more stable. I just started it up and it worked. No tweaking.

Subject: [ap-gto] Problems using ASI air pro and AP mounts

I have a strange problem. I am using a c925 on a AP 1600 . I can run it without guiding for about 30 s with fairly round stars.  The moment i try to guide with the phd on the asiair pro, it is all over the place. Unpredictable spikes in both axes.  Has anyone encountered this problem? I will try with phd proper the next time.
